Abstract
Background: In 2016, California transitioned from legalized medical cannabis use to adult-use. Little is known about how this policy change affected medicinal cannabis use among young adults.Objectives: To identify longitudinal groups of medicinal cannabis users and concurrent changes in health- and cannabis use-related characteristics among young adults in Los Angeles between 2014 and 2021.Methods: Cannabis users (210 patients and 156 non-patients; 34% female; ages 18-26 at baseline) were surveyed annually across six waves. Longitudinal latent class analysis derived groups from two factors - cannabis patient status and self-reported medicinal use. Trajectories of health symptoms, cannabis use motives, and cannabis use (daily/near daily use, concentrate use, and problematic use) were estimated across groups.Results: Three longitudinal latent classes emerged: Recreational Users (39.3%) - low self-reported medicinal use and low-to-decreasing patient status; Recreational Patients (40.4%) - low self-reported medicinal use and high-to-decreasing patient status; Medicinal Patients (20.3%) - high self-reported medicinal use and high-to-decreasing patient status. At baseline, Medicinal Patients had higher levels of physical health symptoms and motives than recreational groups (p < .05); both patient groups reported higher level of daily/near daily and concentrate use (p < .01). Over time, mental health symptoms increased in recreational groups (p < .05) and problematic cannabis use increased among Recreational Patients (p < .01).Conclusions: During the transition to legalized adult-use, patterns of medicinal cannabis use varied among young adults. Clinicians should monitor increases in mental health symptoms and cannabis-related problems among young adults who report recreational - but not medicinal - cannabis use.

Ghandour L, Slim A, Abbas N, El-Khoury J. Patterns of cannabis use, perception of harm, and perceived impact of legislative change in an online sample of young adults from Lebanon: insight on recreational users versus dual motive users. Harm Reduct J 2024; 21:41. [PMID: 38360652 PMCID: PMC10868015 DOI: 10.1186/s12954-024-00958-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Accepted: 02/06/2024] [Indexed: 02/17/2024] Open
Abstract
BACKGROUND Lebanon remains as one of the major sources of cannabis worldwide. In 2020, its government passed a legislation enabling the cultivation of local medicinal cannabis. This first study following the legislative change examines the overlapping use of cannabis for recreational/medicinal purposes and characteristics of the distinct cannabis user types. METHODS A total of 1230 young adults (18-24 years) filled an anonymous online survey in early 2020. RESULTS Young adults in the sample were distributed as follows: 33% 18-20 years; 60% males; 94% Lebanese; 75% students; and 89% living with family. The older young adults (21-24), males, those employed, living with non-family members, and who perceived themselves as being a little/lot richer than most were statistically significantly more present in the cannabis user subtypes (recreational only or recreational/medicinal) than non-cannabis users. When dual recreational/medicinal users are compared to recreational users only, the latter seemed to have a more conservative profile of behaviours, attitudes, and perceptions and acts of harm. The prevalence ratio comparing the prevalence of users supporting consuming cannabis "once or twice" in dual motive users vs. recreational users only was 1.13 for "once or twice", 1.25 for "occasionally", 1.64 for "regularly", and 2.4 for "daily". Any other illicit drug use was reported by 1% of the non-cannabis users, 36% of the recreational users only, and 58% of the recreational/medicinal users (p-value < 0.01). Similarly, any prescription drug use was reported by 3% of the non-cannabis users, 16% of the recreational users only, and 28% of both recreational/medicinal users (p-value < 0.01). CONCLUSION The interface between recreational and medicinal cannabis use is complex. Dual motive users may warrant special attention as a subpopulation of cannabis users. This is relevant to contexts experiencing medicinal cannabis legislation changes, such as Lebanon, as policymakers and implementers should be sensitized to the emerging evidence for more data-informed policy changes.

Abstract
Cannabis was legalized for adult use in California in 2016 for individuals 21 and older. Among 18-20-years-olds, who can possess cannabis legally as medical cannabis patients (MCP) but not as non-patient cannabis users (NPU), the impact of adult use legalization (AUL) on cannabis and other substance use is unknown. Two cohorts of 18-20-year-old cannabis users (MCP and NPU) were surveyed, one in 2014-15 (n = 172 "pre-AUL") and another in 2019-20 (n = 139 "post-AUL"), using similar data collection methods in Los Angeles, California. Logistic and negative binomial regressions estimated cohort and MCP differences for cannabis and other drug use outcomes based on past 90-day use. In both pre- and post-AUL cohorts, MCP were more likely to self-report medical cannabis use (p < .001) while the post-AUL cohort reported greater use of edibles (p < .01), but fewer mean days of alcohol (p < .05) and cigarette (p < .01) use in multivariate models. Notably, frequency of cannabis use (days or hits per day) did not significantly differ between the pre- and post-AUL cohorts, except for greater use of edibles, despite potentially greater access to cannabis.

Abstract
PURPOSE Since October 2022, a total of 21 states have enacted both medical-use and adult-use cannabis legalization, each with their own unique set of laws, regulations, implementation, structures, and enforcement ("policies"). Unlike adult-use programs, medical-use programs often represent a safer and affordable option for patients with diverse needs; however, current evidence suggests that medical-use program activity decreases after implementation of adult-use retail. The current study compares medical patient registration data and medical- and adult-use retail data from 3 distinct medical- and adult-use states (Colorado, Massachusetts, and Oregon) in the time after adult-use retail implementation in each state. METHODS To investigate changes in medical cannabis programs with simultaneous adult-use legalization, correlation and linear regression analyses were used to assess outcome measures: (1) medical-use retail sales; (2) adult-use retail sales; and (3) number of registered medical patients in all fiscal quarters after adult-use retail sales were implemented in each state to September 2022. FINDINGS Adult-use cannabis sales increased significantly over time in all 3 states. However, both medical-use sales and number of medical patients registered in the states increased only in Massachusetts. IMPLICATIONS Results indicate that states' preexisting medical-use programs may undergo critical changes after adult-use cannabis legalization is enacted and implemented. Key policy and program differences, such as regulatory differences in the implementation of adult-use retail sales, may have differential impacts on medical-use programs. For continued patient access, it is critical that future research assess the differences within and between states' medical-use and adult-use programs that permit sustainability of medical-use programs alongside adult-use legalization and implementation.

Abstract
Background Recreational cannabis legalization has become more prevalent over the past decade, increasing the need to understand its impact on downstream health-related outcomes. Although prior reviews have broadly summarized research on cannabis liberalization policies (including decriminalization and medical legalization), directed efforts are needed to synthesize the more recent research that focuses on recreational cannabis legalization specifically. Thus, the current review summarizes existing studies using longitudinal designs to evaluate impacts of recreational cannabis legalization on cannabis use and related outcomes. Method A comprehensive bibliographic search strategy revealed 61 studies published from 2016 to 2022 that met criteria for inclusion. The studies were predominantly from the United States (66.2%) and primarily utilized self-report data (for cannabis use and attitudes) or administrative data (for health-related, driving, and crime outcomes). Results Five main categories of outcomes were identified through the review: cannabis and other substance use, attitudes toward cannabis, health-care utilization, driving-related outcomes, and crime-related outcomes. The extant literature revealed mixed findings, including some evidence of negative consequences of legalization (such as increased young adult use, cannabis-related healthcare visits, and impaired driving) and some evidence for minimal impacts (such as little change in adolescent cannabis use rates, substance use rates, and mixed evidence for changes in cannabis-related attitudes). Conclusions Overall, the existing literature reveals a number of negative consequences of legalization, although the findings are mixed and generally do not suggest large magnitude short-term impacts. The review highlights the need for more systematic investigation, particularly across a greater diversity of geographic regions.

Abstract
INTRODUCTION There is substantial debate concerning the impact of cannabis decriminalization and legalization on road safety outcomes. METHODS Seven databases were systematically searched: Embase, MEDLINE, and PsycINFO through Ovid as well as Web of Science Core Collection, SafetyLit, Criminal Justice Database (ProQuest), and Transport Research International Documentation (from inception to June 16, 2021). Eligible primary studies examined group-level cannabis decriminalization or legalization and a road safety outcome in any population. RESULTS A total of 65 reports of 64 observational studies were eligible, including 39 that applied a quasi-experimental design. Studies examined recreational cannabis legalization (n=50), medical cannabis legalization (n=22), and cannabis decriminalization (n=5). All studies except 1 used data from the U.S. or Canada. Studies found mixed impacts of legalization on attitudes, beliefs, and self-reported driving under the influence. Medical legalization, recreational legalization, and decriminalization were associated with increases in positive cannabis tests among drivers. Few studies examined impacts on alcohol or other drug use, although findings suggested a decrease in positive alcohol tests among drivers associated with medical legalization. Medical legalization was associated with reductions in fatal motor-vehicle collisions, whereas recreational legalization was conversely associated with increases in fatal collisions. DISCUSSION Increased cannabis positivity may reflect changes in cannabis use; however, it does not in itself indicate increased impaired driving. Subgroups impacted by medical and recreational legalization, respectively, likely explain opposing findings for fatal collisions. More research is needed concerning cannabis decriminalization; the impacts of decriminalization and legalization on nonfatal injuries, alcohol and other drugs; and the mechanisms by which legalization impacts road safety outcomes.

Daily cannabis use, cannabis use disorder, and any medical cannabis use among US adults: Associations within racial, ethnic, and sexual minoritized identities in a changing policy context. Prev Med Rep 2022; 28:101822. [PMID: 35620050 PMCID: PMC9127402 DOI: 10.1016/j.pmedr.2022.101822] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Accepted: 05/09/2022] [Indexed: 11/05/2022] Open
Abstract
Daily cannabis use, disorder, and medical use were higher among sexual minoritized adults. Magnitudes of association were comparable across racial and ethnic subgroups. Associations with cross-sectional MCL status differed by racial, ethnic, and sexual minoritized subgroup. Cannabis outcome prevalences were generally higher in states with MCLs.
Differences in cannabis use patterns among racial, ethnic and sexual minoritized identity subgroups have been attributed to marginalized identity stressors. However, associations at the intersection of these minoritized identities remain underexplored in a changing medical cannabis law (MCL) context. We estimated medical cannabis and daily cannabis use, and cannabis use disorder (CUD) by intersecting racial, ethnic and sexual minoritized identity subgroups. We included 189,800 adults in the 2015–2019 National Survey on Drug Use and Health identifying as non-Hispanic white, non-Hispanic Black, or Hispanic and self-reported heterosexual, gay/lesbian, or bisexual sexual identity. We estimated the adjusted odds of past-year: (a) any medical cannabis, (b) daily cannabis use (i.e., 300 + days/year), and (c) DSM-5-proxy CUD by sexual identity, stratified by race and ethnicity. Cannabis measures were higher among sexual minoritized groups than heterosexual adults across racial and ethnic subgroups. Bisexual adults had higher odds of any medical cannabis use than their heterosexual counterparts: non-Hispanic white (6.4% vs. 1.8%; aOR = 2.6, 95% CI = [2.5–3.5]), non-Hispanic Black (4.1% vs. 1.7%; aOR = 2.7, 95% CI = [1.6–4.5]), and Hispanic adults (5.3% vs. 1.8 %; aOR = 2.6, 95% CI = [1.9–3.3]). We found heterogeneous associations with state MCL status across subgroups stratified by race and ethnicity. Bisexual adults in MCL states had higher odds of any medical cannabis use among non-Hispanic white (aOR = 2.0, 95% CI = [1.4–2.9]) and Hispanic (aOR = 3.6, 95% CI = [1.2–10.2]) adults compared to their non-MCL counterparts, but this was marginal among non-Hispanic Black bisexual adults (aOR = 1.6, 95% CI = [1.0–2.6]). Studies should assess intended and unintended cannabis policy effects among racial, ethnic, and sexual identity subgroups.

Abstract
Background Eleven states have instituted laws allowing recreational cannabis use leading to growing public health concerns surrounding the effects of cannabis intoxication on driving safety. We hypothesized that after the 2016 legalization of cannabis in California, the use among vehicular injury patients would increase and be associated with increased injury severity. Methods San Diego County’s five adult trauma center registries in were queried from January 2010 to June 2018 for motor vehicle or motorcycle crash patients with completed toxicology screens. Patients were stratified as toxicology negative (TOX−), positive for only THC (THC+), only blood alcohol >0.08% (ETOH+), THC+ETOH, or THC+ with any combination with methamphetamine or cocaine (M/C). County medical examiner data were reviewed to characterize THC use in those with deaths at the scene of injury. Results Of the 11,491 patients identified, there were 61.6% TOX−, 11.7% THC+, 13.7% ETOH+, 5.0% THC+ETOH, and 7.9% M/C. THC+ increased from 7.3% to 14.8% over the study period and peaked at 14.9% post-legalization in 2017. Compared with TOX− patients, THC+ patients were more likely to be male and younger. THC+ patients were also less likely to wear seatbelts (8.5% vs 14.3%, p<0.001) and had increased mean Injury Severity Score (8.4±9.4 vs 9.0±9.9, p<0.001) when compared with TOX− patients. There was no difference in in-hospital mortality between groups. From the medical examiner data of the 777 deaths on scene, 27% were THC+. Discussion THC+ toxicology screens in vehicular injury patients peaked after the 2016 legalization of cannabis. Public education on the risks of driving under the influence of cannabis should be a component of injury prevention initiatives. Level of evidence III, Prognostic
