Threeton EM, Morris PE, Buckner JD. Sexual orientation-based microaggressions and cannabis use outcomes among sexual minority individuals: The impact of negative affect and coping-motivated cannabis use. JOURNAL OF SUBSTANCE USE AND ADDICTION TREATMENT 2024; 160:209293. [PMID: 38272122 PMCID: PMC11060912 DOI: 10.1016/j.josat.2024.209293] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Revised: 10/02/2023] [Accepted: 01/11/2024] [Indexed: 01/27/2024]
Abstract
INTRODUCTION Sexual minority individuals report significantly more cannabis use and problems than their heterosexual peers, possibly due to their frequent experiences with sexual orientation-based microaggressions. As a result, sexual minority individuals may turn to cannabis use to cope with the negative affect associated with these experiences. No known studies have tested this hypothesis; therefore, the current study tested if sexual orientation microaggressions are positively associated with negative affect (anxiety and depression), cannabis coping motives, and cannabis-related outcomes (frequency, problems); if coping motives are positively associated with cannabis-related outcomes; and if negative affect and cannabis use to cope with negative affect serially mediate the relation between sexual orientation microaggressions and cannabis-related outcomes. METHODS Sexual minority undergraduate students who reported cannabis use in the past three months (N = 328; 71.3 % cis-female) completed an online survey. RESULTS Microaggressions were significantly positively correlated with anxiety, depression, coping-motivated cannabis use, cannabis-related problems, non-sexual orientation-related stress, and overt sexual orientation-based discrimination. Additionally, after controlling for non-sexual orientation-related stress and overt sexual orientation-based discrimination, microaggressions were indirectly positively related to cannabis use frequency and problems via the sequential effects of negative affect and coping motives. This relation remained significant when examining negative affect specific to sexual orientation microaggressions and cannabis use to cope with this microaggressions-specific negative affect. CONCLUSIONS Results highlight the adverse impact of sexual orientation microaggressions in terms of negative affect and negative cannabis-related outcomes.

Factors associated with the use of cannabis for self-medication by adults: data from the French TEMPO cohort study. J Cannabis Res 2024; 6:19. [PMID: 38600591 PMCID: PMC11005193 DOI: 10.1186/s42238-024-00230-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Accepted: 03/26/2024] [Indexed: 04/12/2024] Open
Abstract
BACKGROUND Medical cannabis, legalized in many countries, remains illegal in France. Despite an experiment in the medical use of cannabis that began in March 2021 in France, little is known about the factors associated with the use of cannabis for self-medication among adults. METHODS Data came from the French TEMPO cohort and were collected between December 2020 and May 2021. Overall, 345 participants aged 27-47 were included. Cannabis for self-medication was defined using the following questions: 'Why do you use cannabis?' and 'In what form do you use cannabis?'. The penalized regression method "Elastic net" was used to determine factors associated with the use of cannabis for self-medication, with the hypothesis that it is mainly used for pain in individuals who have already used cannabis. RESULTS More than half of the participants reported having ever used cannabis (58%). Only 10% used it for self-declared medical reasons (n = 36). All self-medication cannabis users, except one, were also using cannabis for recreational purposes. The main factors associated with cannabis use for self-medication vs. other reasons included cannabis use trajectories, the presence of musculoskeletal disorders, tobacco smoking, and parental divorce. CONCLUSIONS Engaging in cannabis use during adolescence or early adulthood may increase the likelihood of resorting to self-medication in adulthood. Due to the propensity of individuals with cannabis use during adolescence to resort to uncontrolled products for self-medication, this population should be more systematically targeted and screened for symptoms and comorbidities that may be associated with cannabis use.

Abstract
OBJECTIVES There is a paucity of population-level data on marijuana use and mental health and functioning in older adults. METHODS We analyzed cross-sectional data (n = 910) from a well-characterized cohort, the Monongahela-Youghiogheny Healthy Aging Team (MYHAT) study. MYHAT is an age-stratified random sample of the population age 65 years and older from a small-town in the USA. Half the sample was female and half were over 75 (Mean age = 77). Most participants were non-Hispanic White. Marijuana use was assessed by self-report and symptoms of mood disorders were screened using the modified Centers for Epidemiological Studies-Depression Scale and the Generalized Anxiety Disorder screener. Cognition was assessed by the Mini-Mental State Examination and a neuropsychological test battery; functioning using the OARS Activities of Daily Living and Instrumental Activities of Daily Living; and overall assessment using the Clinical Dementia Rating (CDR®). RESULTS One in five MYHAT participants had a history of marijuana use and 5% reported recent use, primarily for pain (41%) and recreation/relaxation (37%). Recent use was associated with cigarette and alcohol use, symptoms of depression or anxiety, and impairments in attention. CONCLUSIONS Twenty-percent of community-dwelling older adults living in a US state where recreational marijuana use is illegal had a history of marijuana use. Recent marijuana use was less common but, consistent with prior research, associated with other substance use and poorer mental health.

Abstract
Background: Cannabis use is increasing among middle-aged and older US adults, populations that are particularly vulnerable to the adverse effects of cannabis. Risks for adverse effects differ by cannabis use patterns, which have become increasingly heterogeneous. Nevertheless, little is known about age differences in such patterns.Objective: To investigate age differences in cannabis use patterns, comparing younger (age 18-49), middle-aged (age 50-64), and older adults (age ≥65).Methods: A total of 4,151 US adults with past 7-day cannabis consumption completed an online survey (35.1% male; 60.1% female; 4.8% identified as "other"). Regression models examined age differences in cannabis use patterns.Results: Compared to younger adults, middle-aged and older adults were more likely to consume cannabis during evening hours (50-64: adjusted odds ratio [aOR] = 2.98, 95% CI 2.24-3.96; ≥65: aOR = 4.23, 95 CI 2.82-6.35); by only one method (50-64: aOR = 1.67, 95% CI 1.34-2.09; ≥65: aOR = 3.38, 95 CI 2.24-5.09); primarily by smoking as the only method (50-64: aOR = 1.52, 95% CI 1.29-1.78; ≥65: aOR = 2.12, 95 CI 1.64-2.74); but less likely to consume concentrated cannabis products (concentrates) with extremely high %THC (50-64: aOR = 0.71, 95% CI 0.54-0.93; ≥65: aOR = 0.30, 95 CI 0.16-0.55). Age differences in cannabis use patterns were also observed between middle-aged and older adults.Conclusion: Findings suggest that middle-aged and older adults may engage in less risky cannabis use patterns compared to younger groups (e.g. lower likelihood of consuming highly potent concentrates). However, findings also underscore the importance of recognizing risks unique to these older demographics, such as smoking-related health events. Consequently, prevention strategies targeting such use patterns are needed.

Abstract
INTRODUCTION Adults over age 50 increasingly use cannabis, but few studies have examined co-occurring psychiatric and substance use disorders (SUDs) in this population. The current study utilized electronic health record (EHR) data to compare adults age 50 + with ICD-10 cannabis codes (cases) and matched controls on common psychiatric and SUDs from 2016 to 2020. METHOD Patients age 50 + from an integrated healthcare system in Hawai'i were identified using ICD-10 codes for cannabis (use, abuse, and dependence) from 2016 to 2018. In a matched cohort design, we selected non-cannabis-using controls (matched on sex and age) from the EHR (n = 275) and compared them to cases (patients with an ICD-10 cannabis code; n = 275) on depressive and anxiety disorders and SUDs (i.e., tobacco, opioid, and alcohol use disorders) over a two-year follow-up period. RESULTS Participants were 62.8 years (SD = 7.3) old on average; and were White (47.8 %), Asian American (24.4 %), Native Hawaiian or Pacific Islander (19.3 %), or Unknown (8.5 %) race/ethnicity. Conditional multiple logistic regression was used to estimate odds ratios comparing cases vs controls. Participants with an ICD-10 cannabis code had a significantly greater risk of major depressive disorder (OR = 10.68, p < 0.0001) and any anxiety disorder (OR = 6.45, p < 0.0001), as well as specific anxiety or trauma-related disorders (e.g., generalized anxiety disorder, PTSD) and SUDs (ORs 2.72 - 16.00, p < 0.01 for all). CONCLUSIONS Over a two-year period, diverse adults age 50 + in Hawai'i with ICD-10 cannabis codes experienced higher rates of subsequent psychiatric and SUDs compared to controls. These findings can guide efforts to inform older adults about possible cannabis-related risks.

Trends in Prevalence of Cannabis Use Disorder Among U.S. Veterans With and Without Psychiatric Disorders Between 2005 and 2019. Am J Psychiatry 2024; 181:144-152.

Abstract
OBJECTIVE Cannabis use disorder diagnoses are increasing among U.S. adults and are more prevalent among people with comorbid psychiatric disorders. Recent changes in cannabis laws, increasing cannabis availability, and higher-potency cannabis may have placed people with cannabis use and psychiatric disorders at disproportionately increasing risk for cannabis use disorder. The authors used Veterans Health Administration (VHA) data to examine whether trends in cannabis use disorder prevalence among VHA patients differ by whether they have psychiatric disorders. METHODS VHA electronic health records from 2005 to 2019 (N range, 4,332,165-5,657,277) were used to identify overall and age-group-specific (<35, 35-64, and ≥65 years) trends in prevalence of cannabis use disorder diagnoses among patients with depressive, anxiety, posttraumatic stress, bipolar, or psychotic spectrum disorders and to compare these to corresponding trends among patients without any of these disorders. Given transitions in ICD coding, differences in trends were tested within two periods: 2005-2014 (ICD-9-CM) and 2016-2019 (ICD-10-CM). RESULTS Greater increases in prevalence of cannabis use disorder diagnoses were observed among patients with psychiatric disorders compared to those without (difference in prevalence change, 2005-2014: 1.91%, 95% CI=1.87-1.96; 2016-2019: 0.34%, 95% CI=0.29-0.38). Disproportionate increases in cannabis use disorder prevalence among patients with psychiatric disorders were greatest among those under age 35 between 2005 and 2014, and among those age 65 or older between 2016 and 2019. Among patients with psychiatric disorders, the greatest increases in cannabis use disorder prevalences were observed among those with bipolar and psychotic spectrum disorders. CONCLUSIONS The findings highlight disproportionately increasing disparities in risk of cannabis use disorder among VHA patients with common psychiatric disorders. Greater public health and clinical efforts are needed to monitor, prevent, and treat cannabis use disorder in this population.

Abstract
Introduction: Legal access to and attitudes toward cannabis are changing rapidly. Most of the United States and territories allow adults to use medical and/or recreational cannabis. Recent trends demonstrate increasing cannabis use among older U.S. adults. However, little research has examined cannabis use among older adults since 2019, when the COVID-19 pandemic caused major changes in patterns of substance use. Methods: The National Poll on Healthy Aging is a nationally cross-sectional survey that asked U.S. adults ages 50-80 in January 2021 about their cannabis use in the past year. Multivariable logistic regression was used to identify demographic and health characteristics associated with cannabis use. Results: Among 2023 participants aged 50-80 (52.7% female), 12.1% reported cannabis use in the past year. Among those who reported cannabis use, 34.2% reported using cannabis products 4 or more days per week. In multivariable logistic regression, cannabis use was less likely among people who identified as Hispanic ethnicity or as "other" races compared with non-Hispanic white respondents. Cannabis use was more likely among unmarried/unpartnered and unemployed respondents. Those who consumed alcohol were more likely to use cannabis. Conclusions: More than one in 10 U.S. adults aged 50-80 used cannabis in the 1st year of the COVID-19 pandemic, and many used cannabis frequently. As access to and use of cannabis continue to increase nationally, clinicians and policymakers should monitor and address the potential risks among older adults.

Abstract
Importance Epidemiological studies have found that cannabis increases the risk of a motor vehicle collision. Cannabis use is increasing in older adults, but laboratory studies of the association between cannabis and driving in people aged older than 65 years are lacking. Objective To investigate the association between cannabis, simulated driving, and concurrent blood tetrahydrocannabinol (THC) levels in older adults. Design, Setting, and Participants Using an ecologically valid counterbalanced design, in this cohort study, regular cannabis users operated a driving simulator before, 30 minutes after, and 180 minutes after smoking their preferred legal cannabis or after resting. This study was conducted in Toronto, Canada, between March and November 2022 with no follow-up period. Data were analyzed from December 2022 to February 2023. Exposures Most participants chose THC-dominant cannabis with a mean (SD) content of 18.74% (6.12%) THC and 1.46% (3.37%) cannabidiol (CBD). Main outcomes and measures The primary end point was SD of lateral position (SDLP, or weaving). Secondary outcomes were mean speed (MS), maximum speed, SD of speed, and reaction time. Driving was assessed under both single-task and dual-task (distracted) conditions. Blood THC and metabolites of THC and CBD were also measured at the time of the drives. Results A total of 31 participants (21 male [68%]; 29 White [94%], 1 Latin American [3%], and 1 mixed race [3%]; mean [SD] age, 68.7 [3.5] years), completed all study procedures. SDLP was increased and MS was decreased at 30 but not 180 minutes after smoking cannabis compared with the control condition in both the single-task (SDLP effect size [ES], 0.30; b = 1.65; 95% CI, 0.37 to 2.93; MS ES, -0.58; b = -2.46; 95% CI, -3.56 to -1.36) and dual-task (SDLP ES, 0.27; b = 1.75; 95% CI, 0.21 to 3.28; MS ES, -0.47; b = -3.15; 95% CI, -5.05 to -1.24) conditions. Blood THC levels were significantly increased at 30 minutes but not 180 minutes. Blood THC was not correlated with SDLP or MS at 30 minutes, and SDLP was not correlated with MS. Subjective ratings remained elevated for 5 hours and participants reported that they were less willing to drive at 3 hours after smoking. Conclusions and relevance In this cohort study, the findings suggested that older drivers should exercise caution after smoking cannabis.

Abstract
Purpose of Review With the rapidly changing landscape of state level legalization of cannabis, older adults have become one of the fastest growing populations seeking medical cannabis (MC). However, research evidence on the risks and benefits of MC use in this population remains limited. This review aims to synthesize recent literature on the impacts of MC use in older adults and identify critical knowledge gaps to be addressed in future research. Recent Findings Recent literature showed that older adults often face financial and/or educational barriers and stigma associated with MC access. Emerging data showed that MC may have therapeutic effects on symptoms of conditions such as chronic pain, insomnia, anxiety/depression, dementia, nausea, and vomiting. However, available evidence is inconsistent and tends to rely on self-report and uncontrolled studies. While some adverse events associated with MC use were reported, it is generally well tolerated in older adults. Neurocognitive and psychological consequences and cardiovascular risks have been reported but again only in limited studies with inconsistent findings. Summary There is a need for more systematic and rigorous research on MC in older adults to determine its safety and efficacy. Research on dosing procedures and product characteristics, as well as how these may impact health outcomes, is crucial. More consistent evidence is needed to inform policy changes and patient/physician education to minimize potential risks and optimize benefits among older adults seeking MC as an alternative treatment.

Abstract
Introduction: Cannabis use to alleviate medical symptoms is increasing in middle-aged and older adults. Cognitive impairment associated with cannabis use may be especially detrimental to these understudied age groups. We hypothesized that among middle-aged and older adults who used cannabis for 12 months, frequent (≥3 days/week) compared with nonfrequent (≤2 days/week) use will be associated with cognitive impairment. Materials and Methods: We performed secondary analysis on data from a clinical trial of cannabis use for medical symptoms. Participants (n=62) were ≥45 years, and completed a baseline and at least one postbaseline visit. Cognitive domains were assessed through the Cambridge Neuropsychological Test Automated Battery. Cannabis use was assessed prospectively through daily smartphone diaries. Frequency of cannabis use was a binary predictor in a mixed-effects logistic regression model predicting cognitive impairment adjusted for baseline cognitive functioning. Results: At baseline, participants were primarily nonfrequent cannabis users; however, in all other time periods, most participants were frequent users (range: 55-58%). Cognitive outcomes did not differ between frequent and nonfrequent cannabis users. However, in sensitivity analyses, respondents with problematic cannabis use scored significantly worse on one cognitive domain compared to those without problematic cannabis use. Conclusions: In a clinical sample of adults aged ≥45 years, no longitudinal associations were found between cannabis use and cognitive functioning. However, a few significant associations were observed between problematic use and cognitive functioning. Further research is needed to assess the impact of cannabis use on adults, particularly those aged ≥65 years, and to investigate potential subtler influences of cannabis use on cognition.

Abstract
The goals of this study were to identify patterns of polysubstance use and their associations with stressful life events among U.S. late middle-aged and older adults and examine whether gender moderates these associations. Adults aged 50 and older (N = 14,738) from the National Epidemiological Survey on Alcohol and Related Conditions-III were included. Latent class analysis was conducted to identify patterns of polysubstance use. Weighted multinomial logistic regression was estimated with a generalized structural equation model. Three different polysubstance use patterns (non-users/low substance users; cannabis and excessive alcohol users; painkiller and sedative/tranquilizer misusers) were identified. Higher levels of stressful life events were associated with patterns of polysubstance use. Gender moderated the association between stressful life events and co-misusing painkillers and sedatives/tranquilizers (p < 0.05). Substance use prevention efforts should consider aging adults' patterns of polysubstance use and associated stressful life events when designing and implementing gender-specific polysubstance use prevention interventions.

Abstract
Introduction: Cannabis use among arthroplasty patients has dramatically increased throughout the United States. Despite this trend, knowledge remains particularly limited regarding the effects of cannabis use on perioperative outcomes in total hip arthroplasty (THA). Therefore, the goal of this research was to investigate how cannabis use affects risk of perioperative outcomes, cost and length of stay (LOS) after THA. Materials and Methods: The National Inpatient Sample was used to identify 331,825 patients who underwent primary THA between 2010 and 2014 using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9) procedure code 81.51. Patients with an ICD-9 diagnosis code correlating to history of thromboembolic events, cardiac events, or active substance use other than cannabis were eliminated. The ICD-9 diagnosis codes for cannabis use (304.3-304.32, 305.2-305.22) were used to identify 538 patients with active use. Cannabis users were matched 1:1 to nonusers on age, sex, tobacco use, and comorbidities. The chi-square test was used to determine risk of major and minor complications, whereas the Kruskal-Wallis H test was used to compare hospital charges and LOS. Results: A total of 534 (99.3%) patients with cannabis use were successfully matched with 534 patients without cannabis use. Risk of major complications among cannabis users (25, 4.68%) was similar to that of nonusers (20, 3.74%, p=0.446). Minor complications also occurred at similar rates between cannabis users (77, 14.4%) and nonusers (87, 16.3%, p=0.396). LOS for cannabis users (3.07±2.40) did not differ from nonusers (3.10±1.45, p=0.488). Mean hospital charges were higher for cannabis users ($17,847±10,024) compared with nonusers ($16,284±7025, p<0.001). Conclusion: Utilizing statistically matched cohorts within a nationally representative database demonstrated that cannabis use is not associated with increased risk of complications or prolonged LOS after primary THA. However, cannabis use is associated with higher hospital charges.

Cannabis Recreational Legalization and Prevalence of Simultaneous Cannabis and Alcohol Use in the United States. J Gen Intern Med 2023; 38:1493-1500. [PMID: 36451010 PMCID: PMC10160263 DOI: 10.1007/s11606-022-07948-w] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Accepted: 11/14/2022] [Indexed: 12/02/2022]
Abstract
BACKGROUND Simultaneous cannabis/alcohol use, using both substances within a short time interval so that their effects overlap, has a greater risk of potential negative consequences than single-substance use and is more common in younger age. Relationships between recreational cannabis laws (RCLs) and changes in simultaneous cannabis/alcohol use prevalence remain untested. OBJECTIVE To examine trends in simultaneous cannabis/alcohol use from 2008 to 2019, and investigate associations between implementation of RCLs (i.e., presence of active legal dispensaries or legal home cultivation) and simultaneous cannabis/alcohol use in the United States (U.S.). DESIGN Repeated cross-sectional samples from the 2008-2019 U.S. National Survey on Drug Use and Health (NSDUH). PARTICIPANTS Respondents (51% female) aged 12 and older. INTERVENTIONS Changes in simultaneous cannabis/alcohol use before and after RCL implementation (controlling for medical cannabis law implementation) were compared in different age groups (12-20, 21-30, 31-40, 41-50, 51+), using adjusted multi-level logistic regression with state random intercepts and an RCL/age group interaction. MEASUREMENTS Self-reported simultaneous cannabis/alcohol use. RESULTS From 2008 to 2019, the overall prevalence of simultaneous cannabis/alcohol use declined among those aged 12-20 but increased in adults aged 21+. Model-based simultaneous cannabis/alcohol use prevalence increased after RCL implementation among respondents aged 21-30 years (+1.2%; aOR= 1.15 [95%CI = 1.04-1.27]), 31-40 years (+1.0; 1.15 [1.04-1.27]), and 41-50 years (+1.75; 1.63 [1.34-1.98]), but not in individuals aged <21 or 51+ years. CONCLUSIONS Implementation of recreational cannabis policies resulted in increased simultaneous use of cannabis and alcohol, supporting the complementarity hypothesis, but only among adults aged 21+. Efforts to minimize harms related to simultaneous cannabis/alcohol use are critical, especially in states with RCLs. Future studies should investigate cultural norms, perceived harm, and motives related to simultaneous use.

Subst Use Misuse 2023; 58:858-870. [PMID: 37096682 DOI: 10.1080/10826084.2023.2188427] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 04/26/2023]
Abstract
Background: Substance use (SU) is associated with physical injury and mental health disorders in older persons, but recent research has scarcely examined SU in U.S. Vietnam-era veterans who are mostly in or near their eighth decade of life. Objectives: We compared the prevalence of self-reported lifetime and current SU and modeled current usage patterns in a nationally representative sample of veterans versus a matched nonveteran cohort. Methods: Cross-sectional, self-reported survey data were analyzed from the 2016-2017 Vietnam Era Health Retrospective Observational Study (VE-HEROeS) (n = 18,866 veterans, n = 4,530 nonveterans). We assessed lifetime and current alcohol and drug use disorders; lifetime and current use of cannabis, opioids, stimulants, sedatives, "other drugs" (psychedelics, prescription or over-the-counter drugs not prescribed/used as intended); and current SU patterns (alcohol-use-only, drug-use-only, dual-SU, no SU). Weighted descriptive, bivariable, and multivariable statistics were calculated. Covariates in multinomial modeling included sociodemographic characteristics, lifetime cigarette smoking, depression, potentially traumatic events (PTEs), and current pain (SF-8TM). Results: Prevalence of lifetime opioid and sedative use (p ≤ .01), drug and alcohol use disorders (p < .001), and current "other drug" use (p < .001) were higher in veterans versus nonveterans. Current use of alcohol and cannabis was high in both cohorts. In veterans, very severe/severe pain, depression, and PTEs were highly associated with drug-use-only (p < .001) and dual-SU (p < .01), but these associations were fewer for nonveterans. Conclusion: This research confirmed existing concerns over substance misuse in older individuals. Vietnam-era veterans may be at particular risk due to service-related experiences and later-life tribulations. Era veterans' unique perceptions toward healthcare assistance for SU may need greater provider focus to maximize self-efficacy and treatment.

Abstract
OBJECTIVE To assess the relationship between frequency of cannabis use and sleep duration across age in a large US population (235,667 people). METHODS Multinomial logistic regression was used to evaluate the association between the frequency of cannabis use and sleep duration using cross sectional data from the 2016-2018 Behavioral Risk Factor Surveillance System. RESULTS When adjusted for sociodemographic factors, health related variables, and stratified by age we found that young adults (18-44 years) who reported daily-use (≥16 uses a month) had an increased risk ratio (RR [95% CI]) for either short or long sleep (1.22 [1.06-1.40] and 1.52 [1.07-2.16]); midlife adults (45-64 years) who reported daily-use had an increased prevalence of long sleep (1.71 [1.03-2.82]); and older adults (≥65 years) who reported daily-use had an increased prevalence of short sleep (1.61 [1.05-2.49]). CONCLUSIONS Compared to those who reported no cannabis use, individuals who reported daily cannabis use demonstrated a greater prevalence for either short or long sleep duration.

Associations of cannabis use with motor vehicle crashes and traffic stops among older drivers: AAA LongROAD study. TRAFFIC INJURY PREVENTION 2023; 24:307-314. [PMID: 36939676 DOI: 10.1080/15389588.2023.2180736] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Revised: 02/10/2023] [Accepted: 02/11/2023] [Indexed: 05/23/2023]
Abstract
BACKGROUND Acute cannabis use is associated with a higher risk of motor vehicle crashes (MVC). This study aimed to determine if self-reported past-year cannabis use is associated with MVC or traffic stops among older drivers. METHODS This cross-sectional analysis used data from a multi-center study enrolling active drivers aged 65-79 years. Data regarding cannabis use, MVC, and traffic stops (i.e., being pulled over by police, whether ticketed or not) within the previous 12 months were collected through participant interviews. Log-binomial regression models examined associations of past-year cannabis use with MVC and traffic stops, adjusting for site and sociodemographic and mental health characteristics. RESULTS Of 2,095 participating older drivers, 186 (8.88%) used cannabis in the past year but only 10 (<0.5%) within an hour before driving in the last 30 days; 11.41% reported an MVC and 9.45% reported a traffic stop. Past-year cannabis users had a higher prevalence of MVC (adjusted prevalence ratio [aPR] = 1.38; 95%CI: 0.96, 2.00; p = 0.086) and traffic stops (aPR = 1.58; 1.06, 2.35; p = 0.024). CONCLUSIONS Past-year cannabis use was associated with increased traffic stops, which are correlated modestly with increased MVC in past studies and may indicate impaired driving performance. We did not find a statistically significant association of past-year cannabis use with MVC, which may indicate limited sustained effects on driving performance from periodic use among older adults, who report rarely driving immediately after use.

Impacts of medical and non-medical cannabis on the health of older adults: Findings from a scoping review of the literature. PLoS One 2023; 18:e0281826.

Abstract
BACKGROUND Cannabis legalization has enabled increased consumption in older adults. Age-related mental, physical, and physiological changes may lead to differences in effects of cannabis in older adults compared to younger individuals. OBJECTIVE To perform a scoping review to map the evidence regarding the health effects of cannabis use for medical and non-medical purposes in older adults. METHODS Electronic databases (MEDLINE, Embase, PsycINFO, Cochrane Library) were searched for systematic reviews (SRs), randomized controlled trials (RCTs) and non-randomized/observational studies (NRSs) assessing the health effects and associations of cannabis use (medical or non-medical) in adults ≥ 50 years of age. Included studies met age-related inclusion criteria or involved a priori identified health conditions common among older adults. Records were screened using a liberal accelerated approach and data charting was performed independently by two reviewers. Descriptive summaries, structured tables, effect direction plots and bubble plots were used to synthesize study findings. FINDINGS From 31,393 citations, 133 publications describing 134 unique studies (26 SRs, 36 RCTs, 72 NRSs) were included. Medical cannabis had inconsistent therapeutic effects in specific patient conditions (e.g., end-stage cancer, dementia), with a number of studies suggesting possible benefits while others found no benefit. For medical cannabis, harmful associations outnumbered beneficial, and RCTs reported more negative effects than NRSs. Cannabis use was associated with greater frequencies of depression, anxiety, cognitive impairment, substance use and problematic substance use, accidents/injuries, and acute healthcare use. Studies often were small, did not consistently assess harms, and did not adjust for confounding. DISCUSSION The effects of medical cannabis are inconsistent within specific patient conditions. For older adults, generally, the available evidence suggests cannabis use may be associated with greater frequencies of mental health issues, substance use, and acute healthcare use, and the benefit-to-risk ratio is unclear. Studies with a balanced assessment of benefits and harms may guide appropriate public health messaging to balance the marketing pressures of cannabis to older adults.

Abstract
The objective of this cross-sectional study was to identify cannabis-related features and other characteristics predictive of violence using a data-driven approach in patients with severe mental disorders (SMDs). A Least Absolute Shrinkage and Selection Operator regularization regression model was used on the database consisting of 97 patients with SMD who completed questionnaires measuring substance use and violence. Cannabis use, particularly related to patients' decision to consume or time spent using, was a key predictor associated with violence. Other patterns of substance use and personality traits were identified as strong predictors. Regular patterns of cannabis use and interpersonal issues related to cannabis/stimulant abuse were inversely correlated to violence. This study identified the effect of several predictors correlated to violence in patients with SMD using a regularization regression model. Findings open the door to better identify the profiles of patients that may be more susceptible to perpetrate violent behaviors.

Abstract
Consumption of cannabis is on the rise as public opinion trends toward acceptance and its consequent legalization. Specifically, the senior population is one of the demographics increasing their use of cannabis the fastest, but research aimed at understanding cannabis' impact on the aged brain is still scarce. Aging is characterized by many brain changes that slowly alter cognitive ability. One process that is greatly impacted during aging is axonal myelination. The slow degradation and loss of myelin (i.e., demyelination) in the brain with age has been shown to associate with cognitive decline and, furthermore, is a common characteristic of numerous neurological diseases experienced in aging. It is currently not known what causes this age-dependent degradation, but it is likely due to numerous confounding factors (i.e., heightened inflammation, reduced blood flow, cellular senescence) that impact the many cells responsible for maintaining overall homeostasis and myelin integrity. Importantly, animal studies using non-human primates and rodents have also revealed demyelination with age, providing a reliable model for researchers to try and understand the cellular mechanisms at play. In rodents, cannabis was recently shown to modulate the myelination process. Furthermore, studies looking at the direct modulatory impact cannabis has on microglia, astrocytes and oligodendrocyte lineage cells hint at potential mechanisms to prevent some of the more damaging activities performed by these cells that contribute to demyelination in aging. However, research focusing on how cannabis impacts myelination in the aged brain is lacking. Therefore, this review will explore the evidence thus far accumulated to show how cannabis impacts myelination and will extrapolate what this knowledge may mean for the aged brain.

Abstract
Abstract
Background
As of 2021, 21 US states and territories allowed recreational cannabis use. Although previous research has identified an overall increase in prevalence of cannabis use after legalization, it has been less clear how this change will affect different parts of the population, including older adults, and specifically Baby Boomers, born 1946–1964, given their historically higher rates of use and a higher prevalence of comorbid conditions that could be either exacerbated or addressed by cannabis use. In this study we assessed whether implementation of recreational retail sales in California was associated with increased prevalence of cannabis use among Baby Boomers.
Methods
We conducted a retrospective study of cannabis use prevalence one year before and after the implementation of recreational retail sales in California using the California Health Interview Survey (CHIS), a statewide public health surveillance dataset.
Results
We found that cannabis use prevalence did not change among Baby Boomers but increased among non-Baby Boomers. Most of the factors found to be predictive of cannabis use in past research did not predict cannabis use among Baby Boomers.
Conclusions
Baby Boomers did not change their consumption of cannabis in the first year after opening the retail market, despite previous research suggesting that cannabis consumption increases with access, and most previously identified predictors of use did not identify people who use cannabis in this generation. Further research is needed to determine whether these effects persist over time.

Abstract
BACKGROUND The health risks faced by older adults are diverse; however, little has been explored about the use and abuse of psychoactive substances in this population. The seclusion imposed by the situation that prevails due to SARS-CoV-2 has increased the feelings of loneliness, isolation and sadness associated with this age, which makes them a risk factor for drug use. OBJECTIVE To analyze the consumption of legal and illegal drugs in people over 60 years of age who are Facebook users and its relationship with symptoms of depression during the SARS-CoV-2 pandemic. MATERIAL AND METHODS Study carried out on 380 elderly people, Facebook users, who answered a questionnaire published online, which inquired about: sociodemographic data, frequency and amount of legal and illegal drug use, and depressive symptomatology. RESULTS 50.26% were women; the average age was 66.79 years (SD=5.81); 31.05% consumed alcohol in the last 30 days, 22.63% tobacco, tranquilizers without medical prescription 16.05% and marijuana 7.89%. The consumption of other illegal drugs did not exceed 2.6% of the population. When comparing between users and non-users, it turned out that consumption in the last 30 days was slightly higher in women, in single people and no differences were observed depending on the level of schooling. Mild and severe depressive symptoms were found to be associated with all drugs except tobacco and opiates. DISCUSSION AND CONCLUSIONS The results obtained demonstrate the need to make drug use visible among older adults and to develop strategies that reduce the mood disorders they may be experiencing, such as fear, anguish and depression. When comparing between users and non-users, it turned out that consumption in the last 30 days was slightly higher in women, in single people and no differences were observed depending on the level of schooling.

Abstract
BACKGROUND The prevalence of substance use disorders (SUDs) among adults ages 65 and older has been increasing at a notably high rate in recent years, yet little information exists on hospitalizations for SUDs among this age group. In this study we examined trends in hospitalizations for alcohol use disorders (AUDs) and opioid use disorders (OUDs) among adults 65 and older in the United States, including differences by gender and race/ethnicity. METHODS We used Medicare claims data for years 2007-2014 from beneficiaries ages 65 and older. We abstracted hospitalization records with an ICD-9 diagnostic code for an AUD or OUD. Hospitalization rates were calculated using population estimates from the United States Census. We examined trends in quarterly hospitalization rates for hospitalizations with AUD/OUD as primary diagnoses, and separately for those with these disorders as secondary diagnoses. We also examined comorbidities for those with a primary diagnosis of AUD/OUD. Analyses were conducted for all hospitalizations with AUD/OUD diagnoses, and separately by gender and race/ethnicity. RESULTS Between the last quarter of 2007 and the third quarter of 2014, AUD hospitalization rates increased from 485 to 579 per million (19%), and OUD hospitalization rates from 46 to 101 per million (120%) and varied by gender (for AUD) and race/ethnicity (for both AUD and OUD). Hospitalization rates were particularly high for Black older adults, as was the increase in hospitalization rates. The increase in hospitalization rates was substantially higher for hospitalizations with AUD (84%) and OUD (269%) as secondary diagnoses. CONCLUSIONS Hospitalizations for AUDs and OUDs among older adults increased at an alarming rate during the observation period, and disparities existed in hospitalization rates for these conditions. Interventions focusing on the needs of older adults with AUD and/or OUD are needed, particularly to address the needs of a growing racially/ethnically diverse older adult population.

Abstract
BACKGROUND Cannabis is among the most consumed psychoactive substances world-wide. Considering changing policy trends regarding the substance, it is crucial to understand more clearly its potential acute and residual adverse effects from a public health viewpoint. Cognitive function is one of the targeted areas with conflicting findings. This meta-review measured the magnitude of acute and residual effects of cannabis on cognition in adolescents and adults provided by meta-analyses and evaluated quality of evidence. METHODS A systematic search was performed in PubMed, PsycINFO, Web of Science and Google Scholar. Meta-analyses were included if they quantitatively examined the performances of users from the general population on cognitive tasks. RESULTS The search retrieved 10 eligible meta-analyses (71 effects sizes, n = 43 761) with evidence ranging from low to moderate quality, which were categorized into domains of cognitive functions: executive functions (k = 7), learning and memory (k = 5), attention (k = 4), processing speed (k = 5), perceptual motor function (k = 2) and language (k = 2). Verbal learning and memory displayed the most robust evidence and were most impaired by acute cannabis intoxication that persisted after intoxication passed. Small-to-moderate acute and residual adverse effects were reported for executive functioning. Cannabis use led to small deficits in inhibitory processes and flexibility, whereas small-to-moderate deficits were reported for working memory and decision-making. Evidence regarding processing speed and attention has shown that cannabis administration induced small-to-moderate adverse effects and residual neurocognitive deficits were observed in heavy cannabis-using youths. Results showed no significant difference between cannabis users and non-users on language, and small-to-moderate effects for simple motor skills. CONCLUSION Meta-analytical data on the acute effects of cannabis use on neurocognitive function have shown that cannabis intoxication leads to small to moderate deficits in several cognitive domains. These acute impairments accord with documented residual effects, suggesting that the detrimental effects of cannabis persist beyond acute intake.

Correlates of cannabis use disorder in the United States: A comparison of logistic regression, classification trees, and random forests. J Psychiatr Res 2022; 151:590-597. [PMID: 35636037 DOI: 10.1016/j.jpsychires.2022.05.021] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2021] [Revised: 05/11/2022] [Accepted: 05/19/2022] [Indexed: 10/18/2022]
Abstract
Although several recent studies have examined psychosocial and demographic correlates of cannabis use disorder (CUD) in adults, few, if any, recent studies have evaluated the performance of machine learning methods relative to standard logistic regression for identifying correlates of CUD. The present study used pooled data from the 2015-2018 National Survey on Drug Use and Health to evaluate psychosocial and demographic correlates of CUD in adults. In addition, we compared the performance of logistic regression, classification trees, and random forest methods in classifying CUD. When comparing the performance of each method on the test data set, classification trees (AUC = 0.84, 95%CI: 0.82, 0.85) and random forest (AUC = 0.83, 95%CI: 0.82, 8.05) performed similarly and superior to logistic regression (AUC = 0.77, 95%CI: 0.74, 0.79). Results of the random forests reveal that marital status, risk propensity, age, and cocaine dependence variables contributed most to node purity, whereas model accuracy would decrease significantly if county type, income, race, and education variables were excluded from the model. One possible approach to improving the efficiency, interpretability, and clinical insights of CUD correlates is the employment of machine learning techniques.

Chronic health conditions, acute health events, and healthcare utilization among adults over age 50 in Hawai'i who use cannabis: A matched cohort study. Drug Alcohol Depend 2022; 234:109387. [PMID: 35279458 DOI: 10.1016/j.drugalcdep.2022.109387] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2021] [Revised: 02/14/2022] [Accepted: 02/28/2022] [Indexed: 01/12/2023]
Abstract
BACKGROUND Research on cannabis-related health outcomes in diverse older adults is limited. The current study utilized a matched cohort study design to compare older adults in Hawai'i with identified cannabis diagnoses and matched controls on chronic health conditions, acute health events, and healthcare utilization from 2016 to 2020. METHOD Patients age 50 + were identified using ICD-10 diagnostic codes for cannabis use, abuse, and dependence using electronic health record data from an integrated health system (Kaiser Permanente Hawai'i). Those with cannabis diagnoses (n = 275) were compared to matched non-using controls (n = 275; based on age, sex) on chronic health conditions (coronary heart disease, hypertension, COPD, chronic non-cancer pain), acute health events (myocardial infarction, respiratory symptoms, stroke, persistent or cyclic vomiting, injuries), and healthcare utilization (outpatient, inpatient, and emergency department visits) following case identification for two years. RESULTS Participants were 19.3% Native Hawaiian/Pacific Islander, 24.4% Asian, 47.8% White, and 8.5% Other/Unknown, with an average age of 62.8 years (SD=7.3). Adjusting for covariates as possible, participants with a cannabis diagnosis had significantly greater risk of coronary heart disease, chronic non-cancer pain, stroke, myocardial infarction, cyclic vomiting, and injuries, over time, compared to controls. Cannabis use was associated with any and greater frequency of outpatient, inpatient, and emergency department visits. CONCLUSIONS In a diverse sample, older adults who used cannabis had worse health conditions and events and used more health services over a two-year period. Future studies should evaluate cannabis-related health outcomes, effects of cannabis problem severity, as well as implications for healthcare in aging populations.

J Am Geriatr Soc 2022; 70:1673-1684. [PMID: 35234291 DOI: 10.1111/jgs.17719] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2021] [Revised: 01/18/2022] [Accepted: 01/26/2022] [Indexed: 12/31/2022]
Abstract
OBJECTIVE To describe the reported prevalence of cannabis use and co-use with prescription medications among older adult patients attending primary care (PC) clinics in Los Angeles, CA. METHODS We used electronic health record (EHR) data from sixty PC clinics part of a university-based, urban healthcare system. Patients' ≥50 years of age with an annual physical examination between July 2019 and May 2020 were eligible for inclusion (n = 42,555). Cannabis use was assessed by clinic staff at the time of the visit and recorded in the EHR. We also used EHR data on clinical characteristics including current prescriptions and comorbidities. RESULTS The median age was 63 years (range: 50-101) and 56% were female. Recent cannabis use was reported by 7.6%, which was higher than tobacco use (4.0%; p < 0.01). Prevalence of cannabis use was higher among patients prescribed psychotropic medications. For instance, 10.9% of patients prescribed benzodiazepines reported cannabis use as compared with 7.3% among patients without a prescription for benzodiazepines (p < 0.01). Patients with neurologic/musculoskeletal medications such as antiepileptics also had a higher prevalence of cannabis use when compared with those without these prescriptions (13.6% vs. 7.6% respectively; p < 0.01) as did those who were prescribed muscle relaxants (10.3% vs. 7.5% respectively; p < 0.01). After adjusting for age, sex, race/ethnicity, and comorbidities those prescribed medications for psychiatric (adjusted OR = 1.5; 95% CI 1.4-1.7), respiratory (adjusted OR = 1.2; 95% CI 1.1-1.3), or neurologic conditions (adjusted OR = 1.4; 95% CI 1.2-1.5) had increased odds of cannabis use compared with those not prescribed these medications. DISCUSSION The prevalence of cannabis use among older adults attending PC clinics in a university-based healthcare system was higher among those prescribed medications, which may interact with cannabis. These findings suggest that key groups of older patients who may benefit from routine PC screening for cannabis use and brief advice.

Abstract
OBJECTIVES To describe the characteristics of U.S. mental health and substance use service programs dedicated/tailored for older adults (age 65+). METHODS Data came from the 2012 and 2019 National Mental Health Services Survey (N-MHSS) and the National Survey of Substance Abuse Treatment Services (N-SSATS). Using Pearson χ2 and Fisher's exact tests, we compared the numbers/proportions of older-adult programs in 2012 and 2019 and examined differences between facilities with or without an older-adult program in 2019. RESULTS From 2012 to 2019, the percent of all mental health and substance use service facilities for adults that had a dedicated/tailored program for older adults increased significantly, from 20.7% to 28.9% for mental health facilities and from 7.1% to 24.8% for substance use facilities, with 101 mental health facilities and 53 substance use facilities serving older adults exclusively in 2019. Compared to facilities without an older-adult program, higher percentages of facilities with such a program offered treatment for co-occurring mental and substance use disorders and supplemental health and social care services. CONCLUSIONS Given the rapidly aging society, more accessible and affordable programs dedicated/tailored for older adults are needed. To achieve this goal and better meet older adults' needs, more detailed data on facility characteristics are needed to build the knowledge base on improving the treatment environment. CLINICAL IMPLICATIONS Programs for older adults should be designed to meet the complex needs of those with mental health and/or substance use problems and incorporate innovative service delivery models that can improve older adults' access.

Abstract
Background and Objectives There is a need to know more about cannabis use among terminally diagnosed older adults, specifically whether it operates as a complement or alternative to palliative care. The objective is to explore differences among the terminal illness population within the Illinois Medical Cannabis Program (IMCP) by their use of palliative care. Research Design and Methods The study uses primary, cross-sectional survey data from 708 terminally diagnosed patients, residing in Illinois, and enrolled in the IMCP. We compared the sample on palliative care utilization through logistic regression models, examined associations between palliative care and self-reported outcome improvements using ordinary least squares regressions, and explored differences in average pain levels using independent t-tests. Results 115 of 708 terminally diagnosed IMCP participants were receiving palliative care. We find increased odds of palliative care utilization for cancer (odds ratio [OR] [SE] = 2.15 [0.53], p < .01), low psychological well-being (OR [SE] = 1.97 [0.58], p < .05), medical complexity (OR [SE] = 2.05 [0.70], p < .05), and prior military service (OR [SE] = 2.01 [0.68], p < .05). Palliative care utilization is positively associated with improvement ratings for pain (7.52 [3.41], p < .05) and ability to manage health outcomes (8.29 [3.61], p < .01). Concurrent use of cannabis and opioids is associated with higher pain levels at initiation of cannabis dosing (p < .05). Discussion and Implications Our results suggest that cannabis is largely an alternative to palliative care for terminal patients. For those in palliative care, it is a therapeutic complement used at higher levels of pain.

Abstract
Despite the adverse effects of substance use on health among individuals with preexisting cardiovascular disease (CVD), little is known about trends and correlates for substance use among individuals with CVD. We examined trends of use in tobacco, alcohol, and cannabis among US adults with heart disease. Using nationally representative data from the 2015–2019 National Survey on Drug Use and Health (N = 7339), we conducted survey-adjusted logistic regression analyses to test the significance of trends in substance use while controlling for sociodemographic factors and related correlates. Results showed that the prevalence of cannabis use among adults with a heart condition significantly increased. Notably, the prevalence of cannabis use increased by 91% among non-Hispanic Whites, while the increasing trends were not present among other racial/ethnic groups. Our results also showed that increase in cannabis use was associated with easier access, lower disapproval, and risk perceptions of cannabis. Special attention is needed to raise awareness of the risk associated with cannabis use among individuals with CVD and the implementation of an early screening and treatment strategy among those with CVD.

Abstract
Studies on criminal behaviors largely focus on youth and younger adults. While criminal engagement declines with age, the aging population and significant costs associated with older offenders warrant their increased clinical and research attention. The present study utilizes data from the 2002 to 2017 National Survey on Drug Use and Health to estimate the prevalence and explore the sociodemographic and psychosocial correlates of criminal behavior in adults aged 50 years and older. The overall prevalence of older adults engaging in criminal behaviors during this time was approximately 1.20%. There was no significant difference in crime involvement between adults aged 50 to 64 years and 65 years and older. Older individuals who committed crimes were more likely to be male and Black and earning low income. Criminality was also associated with use of illicit substances and depression as well as receipt of mental health treatment.

Abstract
Background Medical cannabis use is growing among older adults. In this retrospective study, we aimed to assess the characteristics of older medical cannabis users including the indications, type and amount of cannabis used, perceived changes in symptoms after cannabis use, change in dose of concurrent medications, and adverse effects. Methods Data were collected between October 2014 and October 2020 from patients who were consulting the Canada-wide network of clinics of a medical cannabis provider and who were willing to answer questionnaires based on their medical status. The current study included older adults (≥ 65 years) who completed questionnaires at intake and first follow-up visits. Data were summarized with descriptive statistics, which were compared between men and women with t tests or chi-squared tests. Tests of proportions assessed categorical responses for perceived effects after cannabis use. Logistic regression was used to assess trends in cannabis usage. Results Data included that from 9766 older adult users at intake (mean ± SD age = 73.2 ± 6.8 years, females = 60.0%), among whom 4673 (females = 61.4%) returned for follow-up after 90.6 ± 58 days. The most common primary indication for which medical cannabis was sought was pain (67.7%), which was more common in women, whereas oncological and neurological conditions were more common in men. At follow-up, cannabis oil was used by 81.0% of older adults, among whom compositions containing only or mostly cannabidiol (CBD) had been used by 83.6%. Adverse effects reported by older adults at the follow-up visit included dry mouth (12.8%), drowsiness (8.6%), and dizziness (4.0%). The majority of older adults reported improvements in pain (72.7%, z = 1482.6, p < 0.0001, compared to worsening or no change), sleep (64.5%, z = 549.4, p < 0.0001), and mood (52.8%, z = 16.4, p < 0.0001), with 35.6% reporting use of a reduced dose of opioids and 19.9% a reduced dose of benzodiazepines. Interpretation Among older adults, medical cannabis is used more often by women, with CBD-containing cannabis oils being the most commonly used. Users reported improved pain, sleep, and mood symptoms at follow-up after cannabis use. This study describes the patterns of use of medical cannabis by older adults and highlights the need for research to determine appropriate indications, precise doses of active ingredients, and short- and long-term outcomes among older adults. Supplementary Information The online version contains supplementary material available at 10.1007/s40266-021-00913-y.

Abstract
A large portion of the U.S. population is justice-involved, an important at-risk population with poor physical/mental health outcomes and increased rates of substance use. Using the 2018 National Survey on Drug Use and Health, the current study assesses marijuana use across level of community-based justice involvement (i.e., arrest, probation, and parole) among adults. Given increasing rates of marijuana use and a relative lack of research, the current study addresses an important gap in the literature. Findings from logistic regression analysis show that adults who had been arrested or were on probation were more likely to use marijuana compared to adults with no justice involvement, while adults on parole were less likely to use marijuana than those on probation. This study offers evidence of differences in marijuana use across level of justice involvement, which may be attributable to other substance use behaviors, and has important implications for criminal justice practice.

Abstract
Background Cannabis is one of the most widely used substances worldwide. Heavy use is associated with an increased risk of cannabis use disorders, psychotic disorders, acute cognitive impairment, traffic injuries, respiratory problems, worse pregnancy outcomes, and there are indications for genotoxic and epigenotoxic adverse effects. International regulation of medical and non-medical cannabis use is changing rapidly and substantially, highlighting the importance of robust public health monitoring. This study aimed to describe the trends of key public health indicators in European Union (27 member states + UK, Norway and Turkey) for the period 2010 to 2019, their public health implications, and to identify the steps required to improve current practice in monitoring of cannabis use and harm in Europe. Methods Data on four key cannabis indicators (prevalence of use, prevalence of cannabis use disorder [CUD], treatment rates, and potency of cannabis products) in Europe were extracted from the United Nations Office on Drugs and Crime, European Monitoring Centre for Drugs and Drug Addiction and the Global Burden of Disease study. For prevalence of use and CUD, the first and last available estimate in each country were compared. For treatment rates and cannabis potency, linear regression models were conducted. Findings Between 2010 and 2019, past-month prevalence of cannabis use increased by 27% in European adults (from 3·1 to 3·9%), with most pronounced relative increases observed among 35-64 year-olds. In 13 out of 26 countries, over 20% of all past-month users reported high-risk use patterns. The rate of treatment entry for cannabis problems per 100,000 adults increased from 27·0 (95% CI: 17·2 to 36·8) to 35·1 (95% CI: 23·6 to 46·7) and has mostly plateaued since 2015. Modest increases in potency were found in herbal cannabis (from 6·9% to 10·6% THC) while median THC values tripled in cannabis resin (from 7·6% to 24·1% THC). Interpretation In the past decade, cannabis use, treatment rates and potency levels have increased in Europe highlighting major concerns about the public health impact of cannabis use. Continued monitoring and efforts to improve data quality and reporting, including indicators of high-risk use and cannabis-attributable harm, will be necessary to evaluate the health impact of international changes in cannabis regulation. Funding This study received no specific funding.

Abstract
Substance misuse is prevalent among older adults involved in the criminal justice system. The different classes of older offenders, primarily defined as individuals 50 years and older, as well as their offending behaviors vary in their association with substance misuse. Most prison health care systems do not adequately integrate substance use services. Screening for and treatment of substance misuse should be part of comprehensive mental health programs tailored to older offenders. This article reviews different types of offenses among older offenders, their association with substance misuse, and available treatment services.

Substance use disorders among adults who are deaf or hard of hearing in the United States. Drug Alcohol Depend 2021; 228:109106. [PMID: 34610517 DOI: 10.1016/j.drugalcdep.2021.109106] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2021] [Revised: 08/31/2021] [Accepted: 09/22/2021] [Indexed: 11/21/2022]
Abstract
BACKGROUND There has been limited research on substance use disorders (SUDs) among individuals who are deaf or hard of hearing (DHH). This study explored associations among activities of daily living, instrumental activities of daily living, major depressive episode, risk perceptions for substance use, religiosity, and past-year SUDs within the DHH population. METHODS Data was drawn from the 2015-2019 National Survey on Drug Use and Health (N = 214,505) to compare rates of past-year SUDs between DHH (weighted % = 5.4) and non-DHH populations. SUD measures included were past-year alcohol, marijuana, pain reliever, and illicit drug use disorders. RESULTS SUDs are more prevalent among the DHH population than the non-DHH population. When adjusted for sociodemographic variables, DHH adults were more likely to report experiencing all four types of measured SUDs. Significant associations were also found between all four measured SUDs and disability status, major depressive episodes, and perception of risk. An association between regular religious service attendance and alcohol, marijuana, or illicit drug use disorders was also identified, as well as an association between peer religiosity and marijuana use disorders. CONCLUSION Given the high prevalence of SUDs and limited understanding of the mechanisms associated with the SUDs within the DHH population, more research is needed to address these issues.

Abstract
BACKGROUND Research shows significant associations of major depression with cannabis and binge alcohol use. However, despite increasing cannabis and binge alcohol use rates among the 50+ age group, research on this age group is scant. Methods: We used the 2015-2019 National Survey on Drug Use and Health data (n = 44,007 age 50+) and multinomial logistic regression models to examine associations of a major depressive episode (MDE) with cannabis and binge alcohol use and co-use and associations of binge alcohol use with nonmedical and medical cannabis use. Results: Of individuals age 50+, 89.6% had no history of MDE, 5.7% had prior-to-past-year MDE, and 4.7% had past-year MDE. The rates of past-month cannabis use were 4.3%, 7.7%, and 11.6% and binge alcohol use were 17.3%, 18.7%, and 19.9% among those with no MDE history, prior-to-past-year MDE, and past-year MDE, respectively. Compared to no MDE history, prior-to-past-year MDE (RRR = 1.70, 95% CI = 1.30-2.23) and past-year MDE (RRR = 1.80, 95% CI = 1.27-2.55) were significantly associated with past-month cannabis use (with or without binge alcohol use). However, MDE status was not associated with past-month binge alcohol use. Among cannabis users, binge alcohol use was significantly associated with nonmedical cannabis use only (RRR = 2.50, 95% CI = 1.95-3.21). Users of cannabis and/or binge alcohol also had a higher likelihood of using tobacco products and illicit drugs. Conclusions: Healthcare professionals treating individuals age 50+ with depression should screen for substance use, provide education on the potential adverse effects of polysubstance use, and help them access treatment for co-occurring depression and substance use problems.

Abstract
In response to the need of more rigorous data on medical cannabis and chronic pain, we conducted a 3-month prospective study incorporating ecological momentary assessment (EMA) to examine the effects of medical cannabis on pain, anxiety/depression, sleep, and quality of life. Data were collected from 46 adults (Mean age=55.7±11.9, 52.2% male) newly initiating medical cannabis treatment for chronic pain. Participants completed a baseline survey, EMA for approximately 1 week pre- and up to 3 weeks post- medical cannabis treatment, and a 3-month follow-up survey. The self-reported EMA data (2535 random and 705 daily assessments) indicated significant reductions in momentary pain intensity (b = -16.5, p < .001, 16.5 points reduction on 0-100 visual analog) and anxiety (b = -0.89, p < .05), and significant increase in daily sleep duration (b = 0.34, p < .01) and sleep quality (b = 0.32, p <.001) after participants initiated medical cannabis for a few weeks. At 3 months, self-reported survey data showed significantly lower levels of worst pain (t = -2.38, p < .05), pain interference (t = -3.82, p < .05), and depression (t = -3.43, p < .01), as well as increased sleep duration (t = 3.95, p < .001), sleep quality (t = -3.04, p < .01), and quality of life (t = 4.48, p < .001) compared to baseline. In our sample of primarily middle-aged and older adults with chronic pain, medical cannabis was associated with reduced pain intensity/inference, lower anxiety/depression, and improved sleep and quality of life.

Drug Alcohol Depend 2021; 225:108842. [PMID: 34186443 DOI: 10.1016/j.drugalcdep.2021.108842] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/22/2021] [Revised: 05/04/2021] [Accepted: 05/05/2021] [Indexed: 11/17/2022]
Abstract
BACKGROUND Despite increasing rates of nonmedical and/or medical cannabis use in the 50+ age group, scant research exists on the associations between cannabis use and prescription medication use. In this study, we examined associations of use of prescription tranquilizers, sedatives, stimulants, and pain relievers, tobacco products, any/binge/heavy alcohol, and illicit drugs with cannabis use and use characteristics among U.S. adults aged 50+ years with past-year mental illness (n = 6454). METHODS Data are from the 2015-2019 National Survey on Drug Use and Health (NSDUH). We used logistic regression models to examine associations of past-month use of each substance with (1) cannabis use among all those with past-year mental illness, and (2) cannabis use characteristics among cannabis users, controlling for severity of mental illness and sociodemographic and health characteristics. RESULTS Of individuals aged 50+, 14.1 % had any past-year mental illness, and 9.7 % of those with mental illness, compared to 4.0 % of those without, reported past-month cannabis use. Compared to nonusers, cannabis users had higher odds of using each substance except antidepressants, with adjusted odds ratios ranging from 1.3 (sedatives) to 3.6 (illicit drugs). Compared to nonmedical cannabis users, medical users had 2-2.5 times higher likelihood of co-use of tranquilizers, sedatives, and prescription pain relievers but lower odds of binge and heavy alcohol use. CONCLUSIONS Cannabis users, especially medical cannabis users, are significantly more likely to use prescription psychotropic or pain medications. Healthcare professionals should assess for poly-substance use and potential adverse effects among older adults with mental illness.

Abstract
BACKGROUND Tetrahydrocannabinol (THC) can alter the coagulation cascade resulting in hypercoagulability. The aim of our study is to evaluate the impact of THC use on thromboembolic complications (TEC) in geriatric trauma patients (GTP). METHODS This is a 2017 analysis of the TQIP database including all GTP (age ≥65 years). Patients were stratified based on THC use. Propensity score matching (1:2 ratio) was performed. RESULTS A total of 2,835 patients were matched (THC+: 945 and THC-: 1,890). Mean age was 70 ± 6 years, 94% sustained blunt injuries, and median ISS was 22[12-27]. Sixty-two percent of patients received thromboprophylaxis, with median time to initiation of 27 h from admission. Overall, the rate of TEC was 2.1% and mortality was 6.0%. THC + patients had significantly higher rates of TEC compared to THC- patients (3.0% vs. 1.7%; p = 0.01). Rates of DVT (2.2% vs 0.6%, p < 0.01) and PE (1.4% vs 0.4%, p < 0.01) were higher in the THC + group. CONCLUSION THC exposure increases the risk of TEC in GTP. Incorporation of THC use into risk assessment protocols merits serious consideration in GTP.

Abstract
Background The US national surveys and data from legal adult use cannabis states show increases in the prevalence of cannabis use among older adults, though little is known about their manner of cannabis consumption. Here, we examine cannabis use frequency, routes of cannabis administration, and co-use with alcohol, focusing on adults aged 50–64 and ≥65. Methods Data come from a general population survey conducted January 2014–October 2016 (N=5492) in Washington state. We first estimate prevalence and trends in cannabis frequency, routes of administration, and co-use with alcohol in gender by age groups (18–29, 30–49, 50–64, ≥ 65). To test associations between cannabis frequency, route of administration, and co-use with alcohol, we then use sample-weighted multinomial regression adjusted for gender, race/ethnicity, marital status, education, employment, and survey year. Sampling weights are used so results better represent the Washington state population. Regressions focus on the 50–64 and ≥65 age groups. Results Among men and women 50–64, the prevalence of no cannabis use in the past 12 months decreased significantly (84.2% in 2014 to 75.1% in 2016 for women, 76.8% in 2014 to 62.4% in 2016 for men). Among those who report past-year cannabis use, oral administration and vaping and other routes of administration increased by 70% and 94%, respectively each year. Almost one-third of women aged 50–64 and one-fifth of women aged ≥65 who use cannabis reported daily/near daily use, and more than one-third of men who use cannabis in all age groups reported daily/near daily use, including 41.9% of those ≥65. Among men, the prevalence of edibles, drinks, and other oral forms of cannabis administration went up significantly with age (6.6% among 18–29, 21.5% among ≥65). Vaping and other administration are more strongly related to regular and daily/near daily use than infrequent use among those ≥65. The pattern of associations between cannabis frequency and co-use with alcohol differed for women vs. men. Conclusions In a general population representative sample of adults living in a state with legal adult use cannabis, the prevalence of cannabis use increased among those aged 50–64 between 2014 and 2016, the prevalence of daily use is substantial, and oral administration and vaping are increasing.

Abstract
INTRODUCTION As cannabis use rises among adults in the U.S., driving under the influence of cannabis represents a public health concern. METHODS In 2020, public-use data from the National Survey on Drug Use and Health were examined, using an analytic sample of 128,205 adults interviewed between 2016 and 2018. The annual prevalence of driving under the influence of cannabis was computed overall, by state, by demographic group, and among cannabis users. Demographic, psychosocial, and behavioral correlates of driving under the influence were tested by multivariate logistic regression. RESULTS The self-reported annual prevalence of driving under the influence of cannabis was 4.5% (95% CI=4.3, 4.6) among U.S. adults, ranging from 3.0% (Texas) to 8.4% (Oregon) in individual U.S. states. Among cannabis users, 29.5% (95% CI=28.6, 30.3) reported driving under the influence of cannabis; the predicted probabilities of driving under the influence of cannabis were highest for those with more frequent use, with daily cannabis users evidencing a 57% predicted probability. Among individuals with symptoms suggestive of a cannabis use disorder, the prevalence of driving under the influence of cannabis was 63.8% (95% CI=60.8, 66.6). Among cannabis users, those reporting driving under the influence of cannabis had higher odds of driving under the influence of other illicit substances, using other illicit drugs, taking part in illegal behavior, and suffering from mental distress, after adjusting for demographic characteristics and psychosocial/behavioral correlates. CONCLUSIONS Findings suggest that prevention efforts should focus on frequent and problem cannabis users and should include content related to other illicit drug use and other drug-impaired driving.

Abstract
OBJECTIVES To examine: (1) correlates of use-to-nonuse (use 13-24 months ago, but no past-year use), initiation/reinitiation (no use 13-24 months ago, but past-year use), and continued use over a 24-month period; and (2) associations of past-year marijuana use disorder with use/nonuse among older adults. METHOD The 2015-2017 National Survey on Drug Use and Health provided data (N = 26,322 aged 50+). We used multinomial and binary logistic regression analyses to compare users-to-nonusers and initiators/reinitiators to continued users (N = 2304). RESULTS In the 50-64 age group, 2.1% were users-to-nonusers, 2.2% initiators/reinitiators, and 7.2% continued users. In the 65+ age group, the corresponding percentages were 0.7%, 0.7%, and 2.4%. Residence in states with medical marijuana laws, nicotine dependence, and other illicit drug use were associated with a lower likelihood of use-to-nonuse than continued use. Alcohol use disorder was associated with a higher likelihood of initiation/reinitiation. Parole/probation status was associated with higher likelihood of use-to-nonuse. Moderate/great marijuana risk perceptions were associated with a higher likelihood of both use-to-nonuse and initiation/reinitiation. The odds of marijuana use disorder did not differ between continued users and initiators/reinitiators or between medical and recreational users. CONCLUSION Most older users continued using over 24 months. Substantial numbers had marijuana and other substance use problems that require treatment.

Abstract
Background: Older Veterans may experience injuries that result in chronic pain and mental health conditions. Given the increasing availability of medical cannabis, it is important to examine if it serves as a viable or undesirable form of care relative to existing approaches.Objectives: We compared cannabis, prescription opioids, and benzodiazepines use between older Veteran and non-Veterans, and identified outcomes of cannabis use among Veterans. Because of the physical and mental conditions experienced by older Veterans we expected Veterans to report higher use of opioids and benzodiazepines compared to non-Veterans.Methods: We collected surveys from individuals aged 60 and older enrolled in the Illinois Medical Cannabis Patient Program and conducted logistic regression to identify factors associated with cannabis, opioids and benzodiazepines use between Veterans (N = 514, 90.2% male) and Non-Veterans (N = 2758, 41.1% male) across biopsychosocial factors.Results: Both groups reported similar levels of pain, quality of life, social satisfaction, and sleep quality. Veterans were more likely to use cannabis for mental health conditions (p = <.001) while they reported lower use for pain-related conditions (p = <.001) than non-Veterans. Veterans were less likely to use opioids (p = .013) and benzodiazepines (p < .01) compared to non-Veterans. Veterans also reported desirable health outcomes of cannabis use for pain, sleep quality, health conditions, and quality of life.Conclusions: Our work provides insights for clinicians and policy makers to consider whether cannabis can be a viable option to reduce or replace opioid and benzodiazepine use by older Veterans with chronic physical and mental health conditions.

Abstract
To develop personalized interventions and improve outcomes in substance-using populations, research is needed on the heterogeneity in substance use patterns and motivations that exists among adult substance users. This study took a person-centered approach to identify profiles of lifetime substance use and discern the psychosocial differences among them. To survey a spectrum of drug use severity, 1106 adults (43.4% women) were recruited from forensic and community samples. Participants reported on the frequency of lifetime substance use across multiple drug categories (sedatives, stimulants, marijuana, heroin, hallucinogens, misuse of prescription drugs) and alcohol use. Latent profile analysis was used to identify distinct profiles of substance use that were then compared on potential risk and maintenance factors for substance use. Four profiles of lifetime substance use emerged that diverged on severity of use and degree of mono vs. polysubstance use (Recreational Marijuana Use, Heavy Multidrug Intoxication, Heavy Marijuana Use, and Heavy Opioid and Polysubstance Use). The profiles differed on affective motivations for substance use (e.g., using to cope vs. using to seek a thrill), age of use onset, drug-related functional impairment, and experiences of childhood maltreatment. Cognitive functioning did not differentiate the heavy substance use profiles. Results provide compelling initial evidence that lifetime patterns of use can be used to identify groups of substance users with distinct risk and maintenance factors. Results highlight affective motivations for substance use and maltreatment history as potential treatment targets and underscore the importance of studying polysubstance use in the context of the opioid epidemic.

Abstract
Objectives: To examine rates and correlates of dual cannabis and prescription pain reliever (PPNR) use and misuse among U.S. individuals aged 50+ who reported past-year cannabis use. Methods: Using the 2015-2018 National Survey of Drug Use and Health, we examined cannabis nonuse/use and PPNR nonuse/use/misuse among all 35,229 respondents, and then focused on 2,632 past-year cannabis users to examine the risk of PPNR use but no misuse and the risk of PPNR misuse, compared to PPNR nonuse. Results: More than one-half of older cannabis users used PPNR in the past year. Multinomial logistic regression results show that the risks of PPNR use/no misuse and PPNR misuse were higher among those who had more chronic medical conditions and a major depressive episode. The risk of PPNR use/no misuse was also associated with high frequency and medical cannabis use. The risk of PPNR misuse was also associated with younger cannabis initiation age and cannabis and other illicit drug use disorders. Conclusions: Correlates of dual cannabis and PPNR use/misuse among older adults are poor physical and mental health problems and problematic cannabis use. Clinical Implications: Older adults with cannabis and PPNR misuse need access to evidence-based treatment, including medication-assisted treatment when needed.

Front Psychiatry 2021; 12:627479. [PMID: 33796032 PMCID: PMC8007792 DOI: 10.3389/fpsyt.2021.627479] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2020] [Accepted: 02/03/2021] [Indexed: 12/03/2022] Open
Abstract
Aims: To describe trends in cannabis use from 2010 to 2019 among Norwegian adolescents and relate these to individual- and municipal-level variables. Design: Data from nationwide repeated cross-sectional surveys collected in 2010-2013 (T1), 2014-2016 (T2), and 2017-2019 (T3) were used to describe secular trends in proportions of adolescent cannabis use. Setting: Cross-sectional surveys in 410 of the total 428 municipalities of Norway. Participants: A total of 628,678 survey responses from adolescents aged ~13-19 years of age, in which 566,912 survey responses were eligible for analyses, representing data from 340 municipalities. Measurements: Respondent's past year cannabis use, time, gender, school grade, municipality, geographical location, and municipality population. Findings: Boys reported overall higher cannabis use, with ~2:1 gender ratio for any past year cannabis use and a 3:1 gender ratio for frequent cannabis use. Adolescents in Eastern Norway reported higher cannabis use compared with other areas in the country, and adolescents from municipalities with a higher population size reported higher rates of cannabis use than smaller municipalities. A gradual increase in cannabis use from T1 to T3 was found in Eastern Norway and in the largest municipalities. More generally, proportions of past year cannabis use showed a marked increase from T2 to T3 across genders, grade/age groups, geographical location, and municipality population, with few exceptions. Conclusions: Our findings indicate that proportions of past year cannabis use have increased among Norwegian adolescents in recent years. Preventive interventions to hinder initiation of cannabis use, as well as measures to address frequent cannabis use among Norwegian adolescents, are needed.

Cannabis Use among Persons with Dementia and Their Caregivers: Lighting up an Emerging Issue for Clinical Gerontologists. Clin Gerontol 2021; 44:42-52.

Abstract
Objectives: Our goal is to illuminate cannabis use among persons with dementia (PwD) and their informal caregivers relative to the use of evidence-based as well as other complementary and alternative care practices. Methods: We analyzed focus group (FG) narratives provided by 26 caregivers of PwD and identified five themes concerning the provision of cannabis to PwD and caregivers' self-use. Results: Three of the 26 caregivers provided PwD cannabis and also used themselves, another 3 of the 26 used themselves only, and all but two of the remaining FG participants indicated they would consider providing cannabis to PwD or using for themselves. These caregivers expressed a desire to obtain more empirically-based information about cannabis and to discuss options with their clinical care providers. Conclusions: A small but significant proportion of caregivers are providing cannabis to PwD as a possible treatment for agitation, sleep disturbances and other problematic secondary symptoms and using for themselves as way to relieve stress. Many other caregivers may start using cannabis upon receiving information and guidance from a credible source. Clinical Implications: Notwithstanding the need for more research, clinical gerontologists and other dementia care specialists are being looked upon to provide information and guidance about the benefits and harms of cannabis use among PwD and their caregivers.

Abstract
OBJECTIVES To assess health-related outcomes associated with medical cannabis use among older patients in Colorado and Illinois enrolled in their home state's medical cannabis program. METHODS Cross-sectional data from anonymous surveys were collected from 139 persons over the age of 60 using medical cannabis in the past year. We used structural equation modeling (SEM) to confirm the hypothesized four-factor structure that includes health-related quality of life (HRQL), health-care utilization (HCU), symptom effects, and adverse events. We then examined associations between cannabis use and self-reported outcome changes using linear regression. RESULTS The four-factor model was the best fitting structure (X2(df) = 81.63 (67), p> X2 = 0.108) relative to reduced structures. We also found that using cannabis 1-4 times per week is associated with 3.30 additional points on the HRQL scale (p < .001), 2.72 additional points on the HCU scale (p < .01), and 1.13 points on pain (p < .001). The frequency of use reported at 5-7 times per week is associated with 4.71 additional HRQL score points (p < .001). No significant associations were observed between the frequency of use and adverse events. CONCLUSIONS We observed how cannabis use outcomes fall into four independent factors, and those using more frequently reported higher values on HRQL, HCU, and pain measures. However, we are cautious about the generalizability of our findings. CLINICAL IMPLICATIONS Clinicians should consider how older patients using medical cannabis can experience positive and negative outcomes simultaneously or separately and assess these outcomes directly along with considering patient self-reports.
