Trends in binge drinking, marijuana use, illicit drug use, and polysubstance use by sexual identity in the United States (2006-2017)

Substance Use Over Time Among Sexual and Gender Minority People: Differences at the Intersection of Sex and Gender

Purpose: Sexual and gender minority (SGM) people are at greater risk for substance use than heterosexual and cisgender people, but most prior work is limited by cross-sectional analyses or the examination of single substance use. This study examined substance use over time among SGM people to identify patterns of polysubstance use at the intersection of sex and gender. Methods: Data were collected annually over 4 years from SGM respondents (n = 11,822) in The Population Research in Identity and Disparities for Equality (PRIDE) Study. Differences in substance use patterns (any prior 30-day use of 15 substances) by gender subgroup were examined with latent class analysis, and multinomial regression models tested relationships between gender subgroup and substance use. Results: Eight classes of substance use were observed. The three most common patterns were low substance use (49%), heavy episodic alcohol use (≥5 alcoholic drinks on one occasion) with some cannabis and tobacco use (14%), and cannabis use with some tobacco and declining heavy episodic alcohol use (13%). Differences observed included lower odds of patterns defined by heavy episodic alcohol use with some cannabis and tobacco use in all gender subgroups relative to cisgender men and persons with low substance use (odds ratios [ORs] 0.26-0.60). Gender expansive people assigned female at birth, gender expansive people assigned male at birth, and transgender men had greater odds of reporting cannabis use with small percentages of heavy episodic alcohol and tobacco use (ORs: 1.41-1.60). Conclusion: This study suggests that there are unique patterns of polysubstance use over time among gender subgroups of SGM people.

Comparing Repeated (Annual) Couples HIV Testing and Counseling to Individual HIV Testing and Counseling Among Male Couples at High Risk of HIV Infection: Protocol for a Randomized Control Trial

BACKGROUND

Couples HIV testing and counseling (CHTC) is now a standard of care prevention strategy recommended by the Centers for Disease Control and Prevention for sexual minority men (SMM) in relationships. Despite standard recommendations that couples complete CHTC every 6-12 months, no study has empirically evaluated the effects associated with CHTC retesting.

OBJECTIVE

This study aims to understand the benefits associated with continued dyadic engagement in the HIV prevention continuum through routine CHTC retesting, which is of particular importance for emerging-adult SMM in relationships who use drugs.

METHODS

Eligible couples for this CHTC retesting trial must already be enrolled in the 4Us trial, where they completed a CHTC session after their baseline survey. The purpose of the original 4Us trial was to test the efficacy of 2 intervention components for CHTC: a communication skills training video and a substance use module. Couples were eligible for the original 4Us trial if they identified as cisgender male, were in a relationship for 3 months or longer, were aged 17 years or older, and communicated in English. At least 1 partner had to be aged 17-29 years, report HIV negative or unknown serostatus, report use of at least 1 drug (cannabis, cocaine or crack, crystal methamphetamine, ketamine, gamma-hydroxybuterate [GHB], psychedelics, ecstasy, prescription medication misuse, opiates, and nitrates) use, and engage in condomless anal sex (CAS) acts with a casual partner or have a main partner who is nonmonogamous or serodiscordant. Those who complete the 4Us 12-month follow-up and remain in a relationship with the partner they participated in 4Us with are offered the opportunity to participate in this CHTC retesting trial. Those consenting are randomized to either CHTC retesting or individual HIV testing. Follow-up assessments are conducted 3 and 6 months after randomization to evaluate the effects of repeat CHTC on 2 primary outcomes: (1) CAS with a casual partner in the absence of preexposure prophylaxis (PrEP), and (2) CAS with a serodiscordant main partner who is not virally suppressed or concurrent CAS between main and casual partners in the absence of PrEP.

RESULTS

The CHTC retesting trial launched in January 2023, and enrollment is ongoing. As of February 2024, the study had enrolled 106 eligible participants (n=53 couples).

CONCLUSIONS

Findings from this CHTC retesting study will contribute to knowledge about the benefits associated with regular (repeated) CHTC testing versus routine individual HIV testing for SMM in relationships. The results of this trial will inform CHTC retesting guidance.

An Examination of Pregaming Behavior and Motives among Sexual and Gender Minority College Students

Introduction: Pregaming is a popular but high-risk drinking behavior common among college students. Although sexual and gender minority (SGM) college students are a vulnerable population with regards to hazardous alcohol use and alcohol consequences, there is currently limited research investigating the pregaming behavior of this group. The present study aimed to (1) examine mean level differences in pregaming behaviors and motives between SGM and non-SGM college students and (2) explore how SGM status was associated with pregaming behaviors and if SGM status moderated the association between motives and pregaming behaviors. Methods: The sample consisted of 485 college student drinkers in the US, with 19% (n = 93) identifying as SGM. All participants completed measures of past 30-day pregaming frequency and quantity (yielding a total pregaming drinks outcome) and drinking consequences experienced on pregaming days. Results: SGM participants consumed significantly fewer pregaming drinks than non-SGM participants, but did not significantly differ on alcohol-related consequences or drinking motives. The pregaming motive of intimate pursuit moderated the association between SGM status and total pregaming drinks, such that non-SGM participants with high intimate pursuit motives drank the heaviest. Conclusions: Our findings suggest that SGM students consume significantly fewer pregaming drinks than their non-SGM counterparts. However, they may be at a similar risk of experiencing pregaming consequences as non-SGM students. SGM students were less susceptible to the effect of intimate pursuit motives on pregaming drink consumption. This study offers support for past research regarding the effects of certain pregaming motives on pregaming drink consumption and consequences.

Are you thinking what I'm thinking? Defining what we mean by "polysubstance use."

The rise in drug overdoses and harms associated with the use of more than one substance has led to increased use of the term "polysubstance use" among researchers, clinicians, and public health officials. However, the term retains no consistent definition across contexts. The current authors convened from disciplines including sociology, epidemiology, neuroscience, and addiction psychiatry to propose a recommended definition of polysubstance use. An iterative process considered authors' formal and informal conversations, insights from relevant symposia, talks, and conferences, as well as their own research and clinical experiences to propose the current definition. Three key concepts were identified as necessary to define polysubstance use: (1) substances involved, (2) timing, and (3) intent. Substances involved include clarifying either (1) the number and type of substances used, (2) presence of more than one substance use disorder, or (3) primary and secondary substance use. The concept of timing is recommended to use clear terms such as simultaneous, sequential, and same-day polysubstance use to describe short-term behaviors (e.g., 30-day windows). Finally, the concept of intent refers to clarifying unintentional use or exposure when possible, and greater attention to motivations of polysubstance use. These three components should be clearly defined in research on polysubstance use to improve consistency across disciplines. Consistent definitions of polysubstance use can aid in the synthesis of evidence to better address an overdose crisis that increasingly involves multiple substances.

Prenatal Substance Use Among Young Pregnant Sexual Minority People

Purpose: Sexual minority (SM) youth have higher rates of substance use and pregnancy but are absent from the prenatal substance use literature. We modeled the impact of SM identity and syndemic factors on prenatal substance use among 14- to 21-year-olds. Methods: Pregnant people completed an online survey (n = 357). Prenatal substance use was regressed on SM identity, controlling for other syndemic factors (e.g., depressive symptoms, intimate partner violence) and household substance use. Results: Pregnant SM participants (n = 125) were primarily bisexual and were more likely to use tobacco and illicit drugs than heterosexual participants (n = 232). The association between SM identity and prenatal tobacco use was not attenuated by syndemic factors, prenatal cannabis use, or household tobacco use. Conclusion: SM people need increased support for smoking cessation to redress health inequities in tobacco use, prevent prenatal exposures to tobacco, and limit the long-term consequences of tobacco use on health.

COVID-19 Concerns, Coping and Perceived Peer Norms: Correlates of Increased Alcohol and Marijuana Use Among Sexual Minority Women

This study explored the impact of COVID-related concerns and other characteristics on alcohol and marijuana use among sexual minority women (SMW). Survey data from a racially/ethnically diverse sample of 338 SMW participants in the Chicago Health and Life Experiences of Women (CHLEW) study were used to examine correlates of three substance use outcomes: frequent intoxication (once a month or more), perceived increase in alcohol use, and perceived increase in marijuana use. Coping motives for alcohol use was positively associated with each of the substance use outcomes. Belief that peers (in terms of age, sexual identity, and gender) used alcohol often to cope was associated with higher odds of frequent intoxication. COVID-19 related financial concerns were positively associated with both frequent intoxication and increased marijuana use. Health and mental health concerns were associated with lower odds of frequent intoxication. Findings underscore the importance of enhancing coping skills, addressing perceived peer coping norms, and providing both economic and social support in intervention efforts.

Trends in Cannabis and Alcohol Use by Sexual Identity in the 2015-2019 National Survey on Drug Use and Health

OBJECTIVE

Sexual minority individuals are at substantially elevated risk for both cannabis use disorder (CUD) and alcohol use disorder (AUD). Although recent increases in the legalization of cannabis have been linked to increases in cannabis use among the general population, few studies have examined if changes in cannabis use and CUD vary by sexual identity. The purpose of the current study was to examine sexual identity differences in trends for CUD and compare them to trends for AUD.

METHOD

We used data from 2015-2019 National Survey on Drug Use and Health to examine annual prevalence and year-specific disparities in cannabis use, CUD, heavy episodic drinking, and AUD. We also examined sex-specific sexual identity differences in linear trends for these substance use outcomes over this 5-year period.

RESULTS

All groups except lesbian females experienced significant increases in cannabis use rates from 2015 to 2019. Heterosexual males, heterosexual females, and bisexual females also experienced significant increases in CUD rates. In contrast, no group exhibited significant increases in heavy episodic drinking or AUD rates. Bisexual women exhibited some of the largest year-specific disparities in cannabis use and CUD as well as the largest growth in disparities across time.

CONCLUSIONS

The few changes in heavy episodic drinking and AUD alongside numerous changes in cannabis use and CUD suggest that changes in cannabis use may be attributable to legalization of cannabis use in many states during this period. Given profound disparities and increasing rates of CUD affecting bisexual females, further research is needed to identify factors that may explain their disproportionate burden.

High-risk polysubstance use among LGBTQ+ people who use drugs in the United States: An application of syndemic theory

BACKGROUND

Compared to heterosexual and cisgender people, lesbian, gay, bisexual, transgender, queer, and other sexual and gender minority (LGBTQ+) people are more likely to develop problems with high-risk polysubstance use. According to syndemic theory, this disparity in high-risk polysubstance use is produced by the LGBTQ+ community's increased vulnerability to experiencing psychosocial (e.g., discrimination, unwanted sex) and structural (e.g., food insecurity, homelessness) conditions, greater likelihood of coping with concurrent health problems (e.g., human immunodeficiency virus [HIV]), and decreased opportunities to develop protective factors (e.g., social support, resilience).

METHODS

Data from 306 LGBTQ+ participants living in the United States (U.S.) with a lifetime history of alcohol and drug use were analyzed; 21.2% reported lifetime problems with 10 different drugs. Bootstrapped hierarchical multiple regression was used to test demographic correlates and syndemic predictors of high-risk polysubstance use. One-way ANOVA and post-hoc comparison tests were used to test subgroup differences by gender.

RESULTS

Results indicated that income, food insecurity, sexual orientation-based discrimination, and social support were associated with high-risk polysubstance use, explaining 43.9% of the variance of high-risk polysubstance use. Age, race, unwanted sex, gender identity-based discrimination, and resilience were not significant. Group comparison tests revealed that, compared to nonbinary people and cisgender sexual minority men and women, transgender individuals experienced significantly higher levels of high-risk polysubstance use and sexual orientation-based discrimination but significantly lower levels of homelessness and social support.

CONCLUSION

This study provided further evidence for conceptualizing polysubstance use as an adverse outcome of syndemic conditions. Harm reduction strategies, anti-discrimination laws, and gender-affirming residential treatment options should be considered in U.S. drug policy. Clinical implications include targeting syndemic conditions to reduce high-risk polysubstance use among LGBTQ+ people who use drugs.

Malignant mesothelioma tumours: molecular pathogenesis, diagnosis, and therapies accompanying clinical studies

The pathetic malignant mesothelioma (MM) is a extremely uncommon and confrontational tumor that evolves in the mesothelium layer of the pleural cavities (inner lining- visceral pleura and outer lining- parietal pleura), peritoneum, pericardium, and tunica vaginalis and is highly resistant to standard treatments. In mesothelioma, the predominant pattern of lesions is a loss of genes that limit tumour growth. Despite the worldwide ban on the manufacture and supply of asbestos, the prevalence of mesothelioma continues to increase. Mesothelioma presents and behaves in a variety of ways, making diagnosis challenging. Most treatments available today for MM are ineffective, and the median life expectancy is between 10 and 12 months. However, in recent years, considerable progress has already been made in understanding the genetics and molecular pathophysiology of mesothelioma by addressing hippo signaling pathway. The development and progression of MM are related to many important genetic alterations. This is related to NF2 and/or LATS2 mutations that activate the transcriptional coactivator YAP. The X-rays, CT scans, MRIs, and PET scans are used to diagnose the MM. The MM are treated with surgery, chemotherapy, first-line combination chemotherapy, second-line treatment, radiation therapy, adoptive T-cell treatment, targeted therapy, and cancer vaccines. Recent clinical trials investigating the function of surgery have led to the development of innovative approaches to the treatment of associated pleural effusions as well as the introduction of targeted medications. An interdisciplinary collaborative approach is needed for the effective care of persons who have mesothelioma because of the rising intricacy of mesothelioma treatment. This article highlights the key findings in the molecular pathogenesis of mesothelioma, diagnosis with special emphasis on the management of mesothelioma.

Associations Between Latent Classes of Trauma Exposure and Minority Stressors and Substance Use Among Cisgender Sexual Minority Women

Psychosocial stressors (e.g., minority stressors, trauma exposure) profoundly impact sexual minority women's (SMW's) risk of alcohol and other drug (AOD) use. However, research has not examined whether there are distinct typologies (i.e., patterns) of psychosocial stressors and whether these vary based on sociodemographic characteristics or are differentially associated with AOD outcomes (e.g., alcohol dependence) among SMW. This study aimed to identify latent classes of SMW reporting distinct typologies of psychosocial stressors and examine predictors and outcomes of latent classes of psychosocial stressors among SMW. Participants included a community sample of 602 SMW (M_age = 39.9, SD = 14.0; 74.0% lesbian; 37.4% White, 36.6% Black, 22.3% Latinx; 26.6% annual income ≤$14,999). Latent class analysis was used to identify typologies of psychosocial stressors. Regression analyses were employed to examine sociodemographic predictors and AOD outcomes of class membership. Three classes of psychosocial stressors emerged. Participants in Class 1 were likely to report relatively low adversity. SMW in Class 2, who reported childhood physical abuse (CPA), severe childhood sexual abuse, and adult physical assault, were vulnerable to discrimination and stigma consciousness. A distinct subgroup of SMW (Class 3) was at heightened risk of CPA, adult sexual assault (ASA), and stigma consciousness. Older SMW, Black SMW, and SMW with lower social support were more likely to be in classes characterized by higher adversity. Older SMW were at disproportionate risk of CPA and ASA. Different combinations of psychosocial stressors were uniquely associated with AOD outcomes. Findings underscore the importance of considering within-group heterogeneity in SMW's differential risk of psychosocial stressors and AOD outcomes. Routine screening of psychosocial stressors across several dimensions, brief interventions targeting AOD outcomes, and policies mitigating structural drivers of SMW's increased risk of trauma and minority stressors may be especially important for older SMW, Black SMW, and SMW who lack social support.

Substance Use and Relationship Functioning Among Young Male Couples

Research shows that, for different sex couples, individual levels of substance use are deleterious for relationship quality (e.g., satisfaction, intimate partner aggression), whereas dyadic concordance is usually protective. However, there has been no research on these effects among male couples, even though they show increased risk for substance use and certain indices of relationship distress (e.g., intimate partner aggression) compared to different sex couples. Male partners also display distinct similarity patterns and norms surrounding substance use, suggesting that there might be unique effects of substance use on relationship quality among this population. We conducted actor-partner interdependence models of substance use on relationship quality (intimate partner aggression, satisfaction) among a large sample of male dyads (N = 934 individuals, N = 467 dyads). Results suggested that there are novel actor, partner, and similarity effects that imply unique pathways to relationship well-being for male couples. These results are discussed in light of future clinical and empirical efforts. [NCT03186534 - 6/12/2017; NCT03284541 - 6/23/2017].

Seeking order in patterns of polysubstance use

PURPOSE OF REVIEW

This review provides an overview of recent developments in understanding polysubstance use patterns across the lifespan, and advances made in the prevention and treatment of harm arising from polysubstance use.

RECENT FINDINGS

A comprehensive understanding of the patterns of polysubstance use is hampered by heterogeneity across study methods and types of drugs measured. Use of statistical techniques such as latent class analysis has aided in overcoming this limitation, identifying common patterns or classes of polysubstance use. These typically include, with decreasing prevalence, (1) Alcohol use only; (2) Alcohol and Tobacco; (3) Alcohol, Tobacco, and Cannabis; and finally (4) a low prevalence, Extended Range cluster that includes other illicit drugs, Novel Psychoactive Substances (NPS), and nonmedical prescription medications.

SUMMARY

Across studies, there are commonalities present in clusters of substances used. Future work that integrates novel measures of polysubstance use and leverages advances in drug monitoring, statistical analysis and neuroimaging will improve our understanding of how and why drugs are combined, and more rapidly identify emerging trends in multiple substance use. Polysubstance use is prevalent but there is a paucity of research exploring effective treatments and interventions.

Digital interventions for substance use disorders in young people: rapid review

BACKGROUND

Young people are disproportionately more likely than other age groups to use substances. The rise in substance use and related harms, including overdose, during the Covid-19 pandemic has created a critical need for more innovative and accessible substance use interventions. Digital interventions have shown effectiveness and can provide more engaging, less stigmatizing, and accessible interventions that meet the needs of young people. This review provides an overview of recent literature on the nature of recently published digital interventions for young people in terms of technologies used, substances targeted, intended outcomes and theoretical or therapeutic models employed.

METHODS

Rapid review methodology was used to identify and assess the literature on digital interventions for young people. An initial keyword search was conducted using MEDLINE the Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects (DARE), Health Technology Assessment Database (HTA) and PROSPERO for the years 2015-2020, and later updated to December 2021. Following a title/abstract and full-text screening of articles, and consensus decision on study inclusion, the data extraction process proceeded using an extraction grid developed for the study. Data synthesis relied on an adapted conceptual framework by Stockings, et al. that involved a three-level treatment spectrum for youth substance use (prevention, early intervention, and treatment) for any type of substance.

RESULTS

In total, the review identified 43 articles describing 39 different digital interventions. Most were early interventions (n = 28), followed by prevention interventions (n = 6) and treatment interventions (n = 5). The identified digital technologies included web-based (n = 14), game-based (n = 10), mobile-based (n = 7), and computer-based (n = 5) technologies, and virtual reality (n = 3). Most interventions targeted alcohol use (n = 20) followed by tobacco/nicotine (n = 5), cannabis (n = 2), opioids (n = 2), ketamine (1) and multiple, or any substances (n = 9). Most interventions used a personalized or normative feedback approach and aimed to effect behaviour change as the intended outcome. Interestingly, a harm reduction approach guided only one of the 39 interventions.

CONCLUSIONS

While web-based interventions represented the most common type of technology, more recently developed immersive and interactive technologies such as virtual reality and game-based interventions call for further exploration. Digital interventions focused mainly on alcohol use, reflecting less concern for tobacco, cannabis, co-occurring substance use, and illicit drug use. Specifically, the recent exacerbation in the opioid crisis throughout North American underlines the urgent need for more prevention-oriented digital interventions for opioid use. The uptake of digital interventions among youth also depends on the incorporation of harm reduction approaches.

Predictors of Empirically Derived Substance Use Patterns Among Sexual and Gender Minority Populations of a Rural Midwestern State

Purpose: The study purpose was to (1) identify latent classes of substance use behaviors among a sample of sexual and gender minority (SGM) adults living in a predominantly rural midwestern state and (2) determine the association between SGM-related discrimination and the empirically derived substance use classes. Methods: We conducted a latent class analysis on 494 responses to a state-wide survey, followed by a multinomial logistic regression to test predictors of class membership, including distal experiences of discrimination and sociodemographic variables. Results: A three-class model fit best and included (1) polysubstance use, (2) binge drinking, and (3) no/low use classes. In the adjusted model, polysubstance class membership was positively associated with cisgender male identity and negatively associated with being 60 years of age or older and college educated. Binge drinking class membership was negatively associated with bisexual/pansexual identity and non-White race/ethnicity. In contrast to hypothesized outcomes guided by the Minority Stress Model, experiences of discrimination were not associated with membership in substance-using classes. Likewise, bisexual/pansexual individuals were not more likely to be members of polysubstance use or binge drinking classes, despite published reports of greater risk of substance use. Conclusion: These contradictions warrant intersectional approaches to advance substance use research, which may provide important evidence for targeted prevention/treatment interventions, particularly among polysubstance users.

Adverse Childhood Experiences and Adult Tobacco Use Among Sexual and Gender Minority Populations: Examining the Role of Mental, Social, and Community Health

Purpose: We sought to evaluate the relationship between adverse childhood experiences (ACEs) and tobacco use, to assess the intersection of sexual orientation or gender identity (SOGI), and to explore risk and protective aspects of mental, social, and community health. Methods: This was a secondary analysis of the sexual and gender minorities (SGM) subsample (n = 1102) from a 2019 Community Health Needs Assessment. Nested binary logistic regression models were created to evaluate associations between ACEs and type of tobacco use: (1) cigarette use versus no cigarette or electronic nicotine delivery systems (ENDS) use, (2) ENDS use versus no cigarette or ENDS use, and (3) dual use versus use of either cigarettes or ENDS. Results: The sample population that reported four or more ACEs and ENDS use had statistically significant adjusted odds ratios (aORs) when adjusting the models for sociodemographic variables (aOR = 2.55; 95% confidence intervals [CIs]: 1.54-4.22), SOGI (aOR = 2.44; 95% CI: 1.46-4.10), current mental health (aOR = 2.23; 95% CI: 1.32-3.75), and social and community health (aOR = 2.19; 95% CI: 1.30-3.71). The sample population that reported poor mental health had statistically significant aORs when adjusting the models for sociodemographic variables, SOGI, and mental health (aOR = 2.26; 95% CI: 1.32-3.89) and social and community health (aOR = 2.06; 95% CI: 1.17-3.54). There was no statistically significant finding related to the other tobacco use variables (tobacco use and dual use). Conclusion: We found that high-risk ACEs were positively associated with cigarette use and ENDS use. SGM populations have differing experiences when considering community and social support.

Perceived Substance Use Risks Among Never Users: Sexual Identity Differences in a Sample of U.S. Young Adults

INTRODUCTION

Lower perceived risk is a well-established risk factor for initiating substance use behaviors and an integral component of many health behavior theories. Established literature has shown that many substance use behaviors are more prevalent among individuals who identify as lesbian, gay, or bisexual than among those who identify as heterosexual. However, potential differences in perceived risk by sexual identity among individuals with no lifetime use have not been well characterized to date.

METHODS

Data on 111,785 adults aged 18-34 years (including 11,377 lesbian, gay, and bisexual adults) were from the 2015-2019 National Survey on Drug Use and Health. Perceived risks (classified as great risk versus less than great risk) were assessed with 11 National Survey on Drug Use and Health survey items regarding 6 different substances (alcohol, cigarettes, marijuana, cocaine, lysergic acid diethylamide, and heroin). Survey-weighted and sex-stratified logistic regression models were used to estimate sexual identity differences regarding perceived great risk among those reporting no lifetime use. Analyses were conducted in 2021-2022.

RESULTS

Gay men, bisexual men, lesbian/gay women, and bisexual women were all significantly less likely than heterosexual peers to perceive great risk associated with specific marijuana, cocaine, lysergic acid diethylamide, and heroin use behaviors. Bisexual men and women were also significantly less likely than heterosexual peers to perceive great risk associated with binge drinking behaviors and smoking ≥1 packs of cigarettes daily.

CONCLUSIONS

This novel investigation among never users provides evidence that lesbian, gay, and bisexual adults perceive significantly lower risks associated with multiple substance use behaviors than heterosexual adults, which may indicate important sexual identity differences in susceptibility to substance use initiation.

Examining the differential protective effects of women's spirituality and religiosity on alcohol and marijuana use by sexual identity

The current study explored how religiosity and spirituality may differentially influence substance use by sexual identity based on a sample of adult sexual minority women (SMW; n = 437 lesbian; n = 323 bisexual) relative to a heterosexual comparison sample (n = 636). We examined three questions: (1) whether spirituality was differentially associated with alcohol and marijuana use by sexual identity; (2) whether religiosity was differentially associated with alcohol and marijuana use by sexual identity; (3) whether observed differences between spirituality or religiosity and substance use by sexual identity persisted after adjusting for religious environment. Measures included spirituality (importance of spirituality), religiosity (importance of religion, attending religious services), and past year substance use (alcohol use disorder [AUD], any marijuana use, and regular marijuana use). Higher levels of spirituality were associated with increased odds of AUD among both lesbian and bisexual respondents relative to heterosexuals. Higher levels of religiosity among lesbian participants were associated with increased odds of AUD relative to heterosexuals with higher levels of religiosity. Consistent with theories of minority stress, findings suggest that spirituality and religiosity are less protective for SMW than heterosexual women and, in some cases, may contribute to greater risk of substance use.

A Review of Disparities in Cannabis Use and Cannabis Use Disorder Affecting Sexual and Gender Minority Populations and Evidence for Contributing Factors

Purpose of Review

Sexual and gender minorities (SGM) appear to be at elevated risk for cannabis use (CU) and cannabis use disorder (CUD) compared to cisgender heterosexuals. However, risk factors remain understudied among SGM. This review aims to summarize evidence for disparities in CU and CUD affecting SGM and factors contributing to these disparities.

Recent Findings

We found strong evidence that sexual minorities are at elevated risk for CU and CUD is elevated for sexual minority women. Evidence supports a concurrent association between minority stress and CUD symptoms. There is robust support for coping motives as a mechanism linking minority stress to subsequent CU and CUD. Studies also point to CU norms and contexts as potential risk factors.

Summary

SGM are at high risk for CU and CUD, and minority stress, CU norms, and contextual factors are implicated. Additional research is needed on CU among gender minorities, prospective effects of risk factors, and interventions for SGM.

Risk and protective factors for heavy episodic drinking among college students: Influence of mental health service use

Objective: This study was designed to assess the relationship between mental health service utilization and heavy episodic drinking (HED) after controlling for demographic and student-level variables. Participants: A national sample of college undergraduate respondents to the 2017-2018 Healthy Minds Study survey (n = 67,427). Methods: Hierarchical logistic regression entering all variables on a single step. Subsequent logistic regression was used to assess interactions between mental health service variables and select demographic and student level variables. Results: Twenty-two demographic and student-level variables were associated with current HED (9 protective and 11 risk factors). Current mental health therapy was associated with a lower risk of current HED while mental health medication use in the past 12 months (but not currently) was associated with a higher risk of HED. Conclusions: Findings provide guidance to college/university community professionals given the responsibility of designing and implementing programs for mitigation of alcohol misuse on their campus.
