Adverse Childhood Experiences and Cannabis Use Among US Adults: Do Poor Health and Disability Influence Types of Cannabis Use?

Background: Research suggests that individuals who experience four or more adverse childhood experiences (ACEs) have increased rates of cannabis use. However, most prior research does not separate recreational and medical usage. Medical cannabis is used legally in many states to treat a variety of health conditions, many of which are also associated with ACEs. Objectives: Therefore, we explore the extent to which medical cannabis users differ from recreational cannabis users and whether medical use is associated with ACEs, poor health, or disability. Accordingly, we ask the following questions: Are ACEs associated with any cannabis use when controlling for measures of poor health and disability? Are ACEs associated with medical cannabis use? Are associations between ACEs and medical cannabis use explained by poor health and/or disability? Results: Using 2019 BRFSS data, we find that ACEs are significantly associated with cannabis use, but that disability and poor health fully account for the effect of ACEs on medical cannabis use. Conclusions: We conclude that practitioners screen for ACEs and disability status when prescribing medical cannabis.

Using Medical Cannabis for Chronic Pain: A Social-Ecological Framework

Early studies suggest medical cannabis (MC) has the potential to benefit people who suffer from chronic pain by offering a less addictive alternative to opioids; however, most investigators agree more research is indicated. Today, in 2023, cannabis remains a Schedule I drug and is an illegal substance in the United States under the Controlled Substances Act of 1970. Despite this designation, as of February 2022, 37 states, three territories, and the District of Columbia allowed using cannabis products to treat certain painful medical conditions. The contradictory status of federal and state legislation regarding cannabis use has resulted in delays and restrictions on relevant research. As a result, an inadequate foundation of knowledge exists needed to inform policy, program, and practice decisions concerning MC to treat pain. Implementing and controlling access to MC is influenced by overlapping individual, interpersonal, community, and organizational influences that all fall under the umbrella of federal and state policies. Increasingly, the legalization and expanded access to MC necessitates the integration of evidence, policy, and social-ecological reality. To adequately delineate these complex factors to anticipate and plan future interventions at multiple levels, we propose a social-ecological framework (SEF) for using MC to treat pain. This SEF assumes the transactional relationship between the individual and the environment and that no single factor can predict behavior or health outcomes. Our framework illustrates five dynamic levels of analysis that interact between dimensions. Key elements and intersections are discussed at the intrapersonal, interpersonal, institutional, community, and policy levels.

"Every Time It Comes Time for Another Shot, It's a Re-Evaluation": A Qualitative Study of Intent to Receive COVID-19 Boosters among Parents Who Were Hesitant Adopters of the COVID-19 Vaccine

COVID-19 vaccine coverage remains low for US children, especially among those living in rural areas and the Southern/Southeastern US. As of 12 September 2023, the CDC recommended bivalent booster doses for everyone 6 months and older. Emerging research has shown an individual may be vaccine hesitant and also choose to receive a vaccine for themselves or their child(ren); however, little is known regarding how hesitant adopters evaluate COVID-19 booster vaccinations. We used an exploratory qualitative descriptive study design and conducted individual interviews with COVID-19 vaccine-hesitant adopter parents (n = 20) to explore COVID-19 parental intentions to have children receive COVID-19 boosters. Three primary themes emerged during the analysis: risk, confidence, and intent, with risk assessments from COVID-19 and COVID-19 vaccine confidence often related to an individual parent's intent to vaccinate. We also found links among individuals with persistent concerns about the COVID-19 vaccine and low COVID-19 vaccine confidence with conditional and/or low/no intent and refusal to receive recommended boosters for children. Our findings suggest that healthcare providers and public health officials should continue making strong recommendations for vaccines, continue to address parental concerns, and provide strong evidence for vaccine safety and efficacy even among the vaccinated.

Reasonable access: important characteristics and perceived quality of legal and illegal sources of cannabis for medical purposes in Canada

BACKGROUND

Throughout the past two decades of legal medical cannabis in Canada, individuals have experienced challenges related to accessing legal sources of cannabis for medical purposes. The objective of our study was to examine the sources of cannabis accessed by individuals authorized to use medical cannabis and to identify possible reasons for their use of illegal sources.

METHODS

Individuals who participated in the Cannabis Access Regulations Study (CANARY), a national cross-sectional survey launched in 2014, and indicated they were currently authorized to use cannabis for medical purposes in Canada were included in this study. We assessed differences between participants accessing cannabis from only legal sources versus from illegal sources in relation to sociodemographic characteristics, health-related factors, and characteristics of medical cannabis they considered important. A secondary analysis assessed differences in satisfaction with various dimensions of cannabis products and services provided by legal versus illegal sources.

RESULTS

Half of the 237 study participants accessed cannabis from illegal sources. Individuals accessing cannabis from illegal sources were significantly more likely to value pesticide-free products, access to a variety of strains, ability to select strain and dosage, ability to observe and smell cannabis, availability in a dispensary, and availability in small quantities than did individuals accessing cannabis from only legal sources (all p < 0.05). Additionally, participants gave significantly higher satisfaction scores to illegal sources than to legal sources on service-related dimensions of cannabis access (all p < 0.05).

CONCLUSION

Our findings contribute to an understanding of reasonable access to medical cannabis from a patient perspective and how to assess whether it has been achieved. Characteristics of cannabis products and services valued by patients and appropriate to their needs should be incorporated into legal medical cannabis programs to promote the use of legal medical sources. While pertaining specifically to medical use of cannabis in Canada, the findings of this study may also be instructive for understanding the use of illegal cannabis sources for non-medical purposes in Canada and provide insight for other jurisdictions implementing cannabis regulations for both medical and non-medical purposes.

Medical cannabis identity and public health paternalism

Objectives

State-dependent and variable lists of medical conditions granting access to medical cannabis in the United States may be an example of public health paternalism. While purporting to ensure that medical use is clearly defined, the variability of approved conditions has created an atmosphere of ambiguity and medical precarity. The purpose of this study is to examine the relationship between "state" and "self" medical cannabis user identities and the ways non-medical users understand their cannabis consumption.

Study design

This is a mixed methods study consisting of semi-structured interviews and survey data.

Methods

In Phase 1, we examined the relationship between self and state-sanctioned cannabis identity, drawing on the 2022 New Frontier Data Consumer Survey of current cannabis consumers (N = 4682). In Phase 2, we conducted eight semi-structured interviews with a separate sample of adults who use cannabis regularly but do not consider themselves "medical consumers".

Results

Self-reported cannabis identity was significantly related to the adoption of a cannabis consumer identity. Those who self-identified as solely medical or recreational consumers were more likely to reject the identity of "cannabis consumer" than those who identified as both. Self-medical identity was overshadowed by use for "wellness" among interviewees. Most interviewees, despite not identifying as medical users, report therapeutic benefit. Their identity as a cannabis consumer, is tied to the definition of "medical cannabis patient" where they live as well as the fluctuating role of cannabis related to their well-being across their lifespan.

Conclusions

The designation of medical vs. nonmedical use of cannabis varies from state to state, which is not the case for other medicine. This highly variable designation may be paternalistic in nature as governments attempt to differentiate between "legitimate" and "illegitimate" use in the context of federal cannabis prohibition. As a result, lines between medical use and wellness are blurred, which impacts consumer self-identity.

Qualitative Research on Cannabis Use Among Youth: A Methodological Review

Recreational cannabis legalization has encouraged research regarding cannabis use among youth, especially the use of qualitative approaches. In fact, alcohol and drug use journals have recently encouraged qualitative submissions and provided criteria to ensure “high-quality” research. This study provides an objective account of the qualitative approaches used by researchers in this field and discusses implications for future research. A methodological review was conducted for studies published between January 2010 and November 2019. Targeted keyword searches in four research databases returned 1956 unique records. Pairs of reviewers independently screened records against eligibility criteria and charted data for study philosophical positioning, methodology, study aims, sampling, sample, data collection, and data analysis. 23 studies met the inclusion criteria. Several gaps in study quality criteria are observed: less than half of the studies specified the overarching methodology and just two stated philosophical positioning, with some methods unjustified. Implications for future research are discussed.

“I Feel Validated”: Participation in a Medical Cannabis Program in the Context of Legalized Recreational Use

We examined the effects of California’s 2016 law legalizing cannabis for recreational use among young adult medical cannabis patients (MCP) and non-patient users (NPU). Three groups of young adult cannabis users ( n = 30) were qualitatively interviewed in Los Angeles between 2020-21: current MCP ( n = 3), who always had a medical cannabis recommendation, NPU ( n = 6), who never had a recommendation, and MCP-to-NPU ( n = 21), who had a recommendation in the past. MCP remained MCP due to greater acceptance of cannabis and lower prices afforded to MCP. MCP-to-NPU and NPU remained NPU due to increased acceptance of cannabis use within their community, greater legal security, and no compelling need for a medical cannabis recommendation. Price increases drove many to purchasing cannabis from unregulated black-market dispensaries. The legalization of cannabis for recreational use led to decisions to transition out of MCP status, destigmatization of cannabis use, increased prices of cannabis, and increased sourcing of cannabis from the black-market.

Use and Perceptions of Opioids Versus Marijuana among Cancer Survivors

Public health concerns regarding opioids and marijuana have implications for their medical use. This study examined use motives and perceived barriers in relation to opioid and marijuana use and interest in use among US adult cancer survivors. Self-administered surveys were distributed using social media to assess use motives and perceived barriers among participants living with cancer. Overall, 40.9% of cancer survivors reported current (past 30-day) use of opioids, 42.5% used marijuana, and 39.7% used both. The most common use motives for either/both drugs were to cope with pain and stress/anxiety (>70%). Highest-rated barriers to using either/both drugs were missing symptoms of worsening illness and not wanting to talk about their symptoms. Controlling for sociodemographics, binary logistic regression indicated that current opioid use was associated with reporting greater barriers to use (OR = 1.17, p = .011; Nagelkerke R-square = .934) and that current marijuana use was associated with reporting greater barriers to use (OR = 1.37, p = .003; Nagelkerke R-square = .921). Cancer survivors report various use motives and barriers to use regarding opioids and marijuana. While use motives and barriers for both drugs were similar, these constructs were differentially associated with use and interest in use across drugs. Understanding patients' perceptions about opioids and marijuana is an essential component to effectively manage symptoms related to a cancer diagnosis and improve quality of life for cancer survivors.

COVID-19’s Impact on Substance Use and Well-Being of Younger Adult Cannabis Users in California: A Mixed Methods Inquiry

Few qualitative studies have examined the impact of COVID-19 on cannabis and alcohol use, and overall well-being among cannabis users. Cannabis users (aged 26-32) were surveyed quantitatively (n=158) and interviewed qualitatively (n=29) in April 2020–May 2021 in Los Angeles. 63.3% of the quantitative sample reported increasing use of either cannabis (29.1%) or alcohol (15.2%) or both (19.0%) following the COVID-19 outbreak. Qualitative data revealed that increases in cannabis and alcohol use were largely attributed to changes in employment and staying at home resulting in fewer impediments and boredom. Themes of loneliness and utilization of various coping strategies were more pronounced among those who increased cannabis and/or alcohol use. For some, increases in cannabis/alcohol use were temporary until participants adjusted to “a new normal” or embraced more adaptive coping strategies. Results suggest monitoring cannabis/alcohol use trends and identifying coping strategies to reduce the pandemic’s impact on substance use and mental health.

An Exploration of Self-Reported Medicinal Cannabis Use Among a Sample of Eastern Canadian Postsecondary Students

In October 2018, prior to the legalization of cannabis in Canada, a survey was completed by 1050 Memorial University of Newfoundland students. Both descriptive quantitative and thematic qualitative data analyzes were used. Approximately 16% of the sample reported ever using cannabis for medicinal purposes (n=175), with only 16.6% of medicinal users reporting authorization by a healthcare provider (HCP). The majority (80.2%) were aware of possible side effects of cannabis. Prior personal experience (65.3%) and peer influence (59.5%) informed participants' medicinal use. Approximately 40% reported having replaced/reduced prescribed medication. Roughly 60% of medicinal users had not disclosed their use to their HCP. Consistent with previous studies, medicinal cannabis use among postsecondary students appears to be largely motivated for mental health related conditions and is grounded in personal experience versus evidence-based guidelines. There is a need for increased communication between HCPs and patients to promote lower-risk use among medicinal cannabis users.

Changes in Medical Cannabis Patient Status before and after Cannabis Legalization in California: Associations with Cannabis and Other Drug Use

It is unknown how patterns of cannabis and other drug use changed among young adult cannabis users as they became, exited or stayed medical cannabis patients (MCPs) after California legalized cannabis for adult use in 2016. A cohort of 18-26 year-old cannabis users was recruited in Los Angeles in 2014-15 (64.8% male; 44.1% Hispanic/Latinx). Based on wave 1 (pre-legalization) and wave 4 (post-legalization) MCP status, four transition groups emerged: MCP, Into MCP, Out of MCP and NPU (non-patient user). Relationships between self-reported medical cannabis use, transition group membership, and cannabis/other drug use outcomes were examined. Changes in cannabis practices were consistent with changes in MCP status. Cannabis days, concentrate use, self-reported medical cannabis use and driving under influence of cannabis were highest among MCP, increased for Into MCP, and decreased for Out of MCP in wave 4. A majority of drug use outcomes decreased significantly by wave 4. Self-reported medical cannabis use was associated with more frequent cannabis use but less problematic cannabis and other drug use. Future studies should continue to monitor the impact of policies that legalize cannabis for medical or recreational use, and medical motivations for cannabis use on young adults' cannabis and other drug use.

"When they say weed causes depression, but it's your fav antidepressant": Knowledge-aware attention framework for relationship extraction

With the increasing legalization of medical and recreational use of cannabis, more research is needed to understand the association between depression and consumer behavior related to cannabis consumption. Big social media data has potential to provide deeper insights about these associations to public health analysts. In this interdisciplinary study, we demonstrate the value of incorporating domain-specific knowledge in the learning process to identify the relationships between cannabis use and depression. We develop an end-to-end knowledge infused deep learning framework (Gated-K-BERT) that leverages the pre-trained BERT language representation model and domain-specific declarative knowledge source (Drug Abuse Ontology) to jointly extract entities and their relationship using gated fusion sharing mechanism. Our model is further tailored to provide more focus to the entities mention in the sentence through entity-position aware attention layer, where ontology is used to locate the target entities position. Experimental results show that inclusion of the knowledge-aware attentive representation in association with BERT can extract the cannabis-depression relationship with better coverage in comparison to the state-of-the-art relation extractor.

Use and Perceptions of Opioids versus Marijuana among People Living with HIV

Objectives: In this study, we examined use of and interest in using opioids and marijuana, particularly in relation to use motives and perceived barriers to use, among people living with HIV (PLWH). Methods: We analyzed online survey data from 304 PLWH in the United States recruited via social media in Summer 2018. Results: In this sample (Mage = 30.86, 40.5% male, 64.5% white), 16.1% reported current (past 30-day) use of opioids, 18.1% marijuana, and 15.8% both. Participants reported more use motives and fewer barriers to using marijuana versus opioids (p's < .001). The most frequently endorsed motive for using either/both drugs were to cope with pain and stress/anxiety. Highest-rated barriers to using either/both drugs were missing symptoms of worsening illness and addiction concerns. Regression analyses indicated that current opioid use correlated with reporting greater opioid use motives; among past-month opioid nonusers, greater interest in using opioids correlated with greater opioid use motives. Current marijuana use correlated with reporting greater marijuana use motives and greater barriers; among past-month marijuana nonusers, greater interest in using marijuana correlated with greater marijuana use motives and fewer barriers. Conclusions: Use motives and barriers differentially correlated with use and interest in use across drugs, thereby indicating different intervention approaches to address appropriate use.

Developmental trajectories of illicit drug use, prescription drug misuse and cannabis practices among young adult cannabis users in Los Angeles

INTRODUCTION AND AIMS

Young adults have the highest rates of drug use and contribute significantly to the growing population of medical cannabis patients (MCP). This study examined relationships between longitudinal patterns of illicit/prescription drug use/misuse and cannabis practices among young adult cannabis users.

DESIGN AND METHODS

In 2014-2015, 210 young adult MCP and 156 nonpatient users were recruited in Los Angeles and surveyed annually over four waves. The analytical sample was limited to completers of all four waves (n = 301). Distinct developmental trajectories of illicit drug use and prescription drug misuse were identified. Fixed effects regression analysis evaluated changes in cannabis practices by trajectory groups.

RESULTS

Results supported two-trajectory solutions (high/low) for illicit drug use and prescription drug misuse. Decreases in use within all four trajectories occurred by wave 4. Low illicit drug use trajectory members were more likely to self-report medical cannabis use. Membership in both types of high-use trajectories was associated with use of concentrates and edibles. The prevalence of MCP, edibles use and cannabis days decreased significantly by wave 4.

DISCUSSION AND CONCLUSIONS

While alternative cannabis forms use was associated with membership in high drug use trajectories, self-reported medical cannabis use (not MCP) was negatively associated with high illicit drug use trajectory membership. Reductions in the prevalence of MCP, cannabis days, edibles use and other drug use by wave 4 alongside stable levels of self-reported medical cannabis use might reflect the changing legal status of cannabis in California, maturing out phenomenon and safer patterns of cannabis use.

The Role of Life Events/Contextual Factors and Cannabis Use in Patterns of Other Drug Use Among Young Adult Cannabis Users in Los Angeles: A Qualitative Inquiry

This analysis examined the role of impactful life events/stressful contextual factors and cannabis use in the patterns of illicit drug use. It utilized semi-structured qualitative interviews with 40 young adult medical cannabis patients and 22 non-patient users collected in Los Angeles during 2014-2015. Three patterns of illicit drug use emerged based on participants' narratives: regular/problematic, recreational/occasional, and never users. Among regular/problematic users, a common theme was the lasting impact of traumatic life events or stressful contextual factors on transition to and away from problematic drug use, and using cannabis to cope with negative after effects of drug use. In contrast, most recreational/occasional and never users, who reported impactful life events or stressful contextual factors, used cannabis to cope with those experiences. Family history of addiction and acceptance of cannabis use within a family as protective factors against illicit drug use among some recreational/occasional and never users was an unexpected finding.

Marijuana sources in a medical marijuana environment: dynamics in access and use among a cohort of young adults in Los Angeles, California

While a range of sources exist for marijuana users to acquire marijuana for medical or personal use, prior research on marijuana sources primarily focused on single sources. In this analysis, we longitudinally examined characteristics of multiple sources selected by marijuana users, motivations to use sources, and how a blend of marijuana sources accommodated users' needs. Young adult marijuana users (n=60) in Los Angeles, CA, where marijuana has been legal for medical use since 1996, completed two annual qualitative interviews on marijuana use practices and sources between 2014 and 2016. Approximately two-thirds were medical marijuana patients and one-third were non-patient users. Participants reported acquiring marijuana from the following primary sources across two interviews: dispensaries and delivery services, private sellers in the illicit market, friends and family, and marijuana events/conferences. While patients with legal medical access to marijuana typically purchased marijuana from dispensaries or delivery services, they often supplemented from other illicit sources. Non-patients often accessed marijuana through dispensary diversion but also other sources. As patients became non-patients and vice versa during the study period, source type changed too. Broad access to marijuana via legal and illicit sources in this sample is indicative of societal trends towards normalization of marijuana use.
