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

Cannabis use trajectories over time in relation to minority stress and gender among sexual and gender minority people

Substance use disparities among sexual and gender minority (SGM) people are attributed to minority stress, but few studies have examined minority stress and cannabis use over time or investigated differences in cannabis use trajectories by less-studied gender subgroups. We examined if longitudinal cannabis use trajectories are related to baseline minority stressors and if gender differences persisted after accounting for minority stress. Cannabis use risk was measured annually over four years (2017-2021) within a longitudinal cohort study of SGM adults in the United States (N = 11,813). Discrimination and victimization, internalized stigma, disclosure and concealment, and safety and acceptance comprised minority stress (n = 5,673). Latent class growth curve mixture models identified five cannabis use trajectories: 'low or no risk', 'low moderate risk', 'high moderate risk', 'steep risk increase', and 'highest risk'. Participants who reported past-year discrimination and/or victimization at baseline had greater odds of membership in any cannabis risk category compared to the 'low risk' category (odds ratios [OR] 1.17-1.33). Internalized stigma was related to 'high moderate' and 'highest risk' cannabis use (ORs 1.27-1.38). After accounting for minority stress, compared to cisgender men, gender expansive people and transgender men had higher odds of 'low moderate risk' (ORs 1.61, 1.67) or 'high moderate risk' (ORs 2.09, 1.99), and transgender men had higher odds of 'highest risk' (OR 2.36) cannabis use. This study indicates minority stress is related to prospective cannabis use risk trajectories among SGM people, and transgender men and gender expansive people have greater odds of trajectories reflecting cannabis use risk.

Young Adults' Experiences with Cannabis Retailer Marketing and Related Practices: Differences Among Sociodemographic Groups and Associations with Cannabis Use-related Outcomes

OBJECTIVES

Limited cannabis retail surveillance has been conducted, particularly assessing retailer practices in relation to consumer sociodemographic factors or use-related outcomes. This study examined young adults': exposure to promotions, health claims, warnings, and age restrictions at cannabis retailers; demographic correlates of retail exposures; and retail exposures in relation to use-related outcomes.

STUDY DESIGN

This study used the cross-sectional quantitative analysis.

METHODS

We analyzed 2023 survey data among 876 young adults in states with legal non-medical cannabis, reporting past-month cannabis use and past-year retailer visits.

RESULTS

In this sample (Mage = 27.1, 44.1% male, 31.7% sexual minority, 17.7% Black, 11.2% Asian, 25.1% Hispanic), 46.7% "at least sometimes" noticed free samples, 76.5% price promotions, 37.4% subpopulation-targeted promotions; 72.5% health claims on products/ads, 63.1% signage, and 70.5% from budtenders; 72.5% warnings on labels, 65.5% signage, and 38.9% from budtenders; and > 80% age verifications. Multivariable analyses identified sociodemographic correlates of exposure outcomes: greater promotion exposure was associated with Black race; greater health claim exposure with being heterosexual, Black, and less educated; less warning exposure with less education; and less age restriction exposure with being younger, male, and Black. Retail exposures were associated with use-related outcomes: more frequent cannabis use was associated with less health claim exposure; greater perceived social acceptability with greater promotion and age restriction exposure; greater perceived risk with greater warning and less age restriction exposure; more problematic use and driving after use with greater promotion and less age restriction exposure.

CONCLUSIONS

Cannabis retail exposure disparities and their associations with use-related outcomes highlight the importance of regulatory and prevention efforts.

Update on cannabis in human sexuality

RATIONALE

Sexuality is a central aspect of being human that encompasses many facets. Cannabis, a widely used psychoactive substance, has been associated with various effects on sexuality. The relationship between cannabis and sexuality is complex and multifaceted, involving physiological, psychological, and social factors.

OBJECTIVES

This review aims to provide an overview of the current literature on the effects of cannabis on several sexual functions, including sexual desire, arousal, orgasm, and sexual satisfaction. It also discusses the potential mechanisms underlying these effects, as well as the impact of dose and frequency of use.

RESULTS

This review has revealed a complex relationship between cannabis dosage and its influence on sexuality. It appears that the frequency of cannabis use in humans has been associated with the frequency of sexual activities. Individuals who use cannabis more frequently tend to report higher levels of sexual activity. Moreover, there is a notable gender difference in how cannabis affects sexuality. In addition, we found lower doses of cannabis to be linked to heightened sexual desire and enjoyment, whereas higher doses may lead to a decrease in sexual desire and performance.

CONCLUSIONS

Overall, the association between cannabis and sexuality is complex and warrants further research to better understand the psychological and neurological mechanisms that underlie the effect of cannabis on these sexuality functions and its implications for sexual health. To advance in this endeavor, a crucial step is establishing a precise measurement of dosage in human studies.

Distal and Proximal Minority Stressors on Patterns of Tobacco and Cannabis Use Among Young Bisexual Women

BACKGROUND

Bisexual women have high rates of tobacco and cannabis use, but few studies have examined co-use behavior in this population. Although the role of distal minority stressors (eg, discrimination) on substance use has been examined, fewer studies have examined proximal minority stressors (eg, negative sexual identity self-schemas). The current study was a secondary data analysis that examined patterns of tobacco and cannabis use, and the role of distal (instability of bisexuality, sexual irresponsibility of bisexual people, and hostility toward bisexual people) and proximal (illegitimacy of bisexuality, anticipated binegativity, internalized binegativity, and identity affirmation) bisexual-specific minority stressors among bisexual women.

METHODS

Participants were 224 young (aged 18-30 years old) self-identified bisexual women who reported on their past 30-day tobacco and cannabis use and completed measures of distal and proximal bisexual-specific minority stressors. Participants were categorized into one of 4 patterns: no use, tobacco use only, cannabis use only, and tobacco and cannabis co-use.

RESULTS

The most common pattern of past 30-day use was tobacco and cannabis co-use (39.1%). Results from a multinomial logistic regression revealed that bisexual women who reported higher illegitimacy of bisexuality, a proximal minority stressor, were significantly more likely to engage in tobacco and cannabis co-use, relative to no use.

DISCUSSION

Bisexual women have particularly high rates of substance use, with tobacco and cannabis co-use as the most common pattern. Incorporating the role of proximal minority stressors, and specifically, beliefs about the legitimacy of bisexuality, may be an important target of substance use interventions for bisexual women.

Disparities in Cannabis Use among Female and Male Sexual Minority Young Adults in the US: The Role of Parenting Behaviors

Introduction

Despite cannabis use disparities among sexual minority (SM; vs. heterosexual) young adults (SMYAs), little research has explored social influences contributing to these disparities. This study examined sexual identity subgroup differences in parenting behaviors and associations among parenting behaviors and cannabis use behaviors among YA subgroups.

Methods

Participants were female (N=416; 44.7% bisexual, 7.2% lesbian) and male (N=228; 11.0% bisexual, 13.2% gay) YAs (ages 18-29) recruited via social media from 6 US cities. Bivariate analyses examined differences in perceived parenting (psychological control, behavioral control, knowledge, autonomy support, warmth, communication, cannabis disapproval), any past-month (current) cannabis use, and current cannabis use frequency across sexual identity subgroups. Multivariable regression examined associations among sexual identity and parenting behaviors with cannabis use outcomes.

Results

Among female YAs, bisexual (vs. heterosexual) YAs had greater odds of cannabis use, reported more frequent use, and reported greater parental psychological control and less behavioral control, autonomy support, warmth, and communication; greater psychological control was associated with both outcomes; less autonomy support was associated with current use; and less warmth and communication were associated with use frequency. Among male YAs, gay and bisexual (vs. heterosexual) YAs had greater odds of current use and reported more frequent use and greater psychological control; gay (vs. heterosexual) YAs reported greater behavioral control and less autonomy support, warmth, and communication; and greater psychological control and less warmth and communication were associated with both outcomes.

Conclusions

Cannabis prevention/cessation programs should target specific parenting behaviors that differentially impact cannabis use outcomes among specific SMYA subgroups.

Examining Associations Between Cannabis Use Disorder and Measures of Weekly and Within-Day Cannabis Frequency, Quantity, and Potency in College Students

Background: College student cannabis use has increased significantly in recent years, and individuals aged 18-25 are at elevated risk for development of cannabis use disorder (CUD). While weekly cannabis use frequency is a commonly used measure of cannabis consumption, there is increasing scientific interest in exploring more nuanced measures of cannabis use. Currently, limited research exists examining the clinical utility of cannabis quantity, within-day frequency, and potency variables. Methods: We used cross-sectional survey data from a sample of 617 undergraduate students in the state of Colorado. A two-part model-building approach was leveraged to examine whether within-session cannabis quantity and within-day cannabis use frequency were associated with odds of experiencing any CUD symptoms and total number of CUD symptoms endorsed. We also examined whether cannabis flower potency was associated with odds of experiencing any CUD symptoms and total number of CUD symptoms endorsed among a subset (N=288) of the sample who reported knowledge of the cannabinoid content of their most frequently used products. Results: Weekly flower use frequency (odds ratio [OR]=1.27, p<0.001) and weekly concentrate use frequency (OR=1.10, p=0.044) were positively associated with increased odds of experiencing any CUD symptoms, but cannabis quantity and within-day frequency variables were not. In addition, no association was found between flower potency and odds of endorsing any CUD symptoms. Among individuals endorsing at least one symptom, weekly flower use frequency (incident rate ratio [IRR]=1.06, p<0.001) was positively associated with total symptom count, but weekly concentrate use frequency, cannabis quantity variables, and within-day frequency variables were not. Among individuals endorsing symptoms, a positive association was found between flower potency and total symptom count (IRR=1.01, p=0.008). Conclusion: Current methods of assessing within-session cannabis quantity and within-day cannabis use frequency may lack clinical utility in examining college student CUD symptoms over and above weekly cannabis use frequency. Cannabis flower potency may prove useful in assessment of CUD symptom severity, but further research is warranted.

The cumulative effects of stigma-related stress: Chronic stigma-related stress exposure exacerbates daily associations between enacted stigma and anxious/depressed affect

PURPOSE

Sexual and gender minority individuals are at elevated risk for mood and anxiety disorders compared to heterosexual and cisgender individuals. Ecological momentary assessments studies have implicated experiences of enacted stigma (i.e., biased treatment) by linking these experiences with elevations in anxious and depressed affect. The current study utilizes a theory from the broader stress and affect literature to determine whether chronic enacted stigma exposure amplifies individuals' negative affective reactions to experiences of enacted stigma at the daily level.

METHODS

We used data from a 30-day ecological momentary assessment study with 429 sexual minority women and gender diverse sexual minorities assigned female at birth (SMWGD) living in the US in 2020-21 to determine whether concurrent and prospective event-level associations between enacted stigma, anxious/depressed affect, and perceived coping efficacy were moderated by chronic enacted stigma exposure.

RESULTS

Results demonstrate that individuals with moderate to high chronic stigma exposure experience larger increases in anxious/depressed affect and larger decreases in perceived coping efficacy following daily experiences of enacted stigma. Further, these effects of daily stigma on anxious/depressed affect persist for longer among individuals with high chronic stigma exposure. Interestingly, chronic stigma exposure did not moderate associations between daily general stressors (i.e., those unrelated to identity) and affect or perceived coping efficacy, suggesting that these effects are specific to stigma-related stressors.

CONCLUSIONS

These results help to advance our understanding of both long-term and daily effects of exposure to enacted stigma, highlighting the potentially profound cumulative effects of stigma exposure and the need to intervene in this cycle.

Prospective examination of mechanisms linking minority stress and anxious/depressed affect at the event level: The roles of emotion regulation strategies and proximal minority stressors

BACKGROUND

While studies have linked sexual minority stress with anxious/depressed affect, few studies have prospectively examined how mechanistic processes linking minority stress and anxious/depressed affect unfold in near-real time. Furthermore, studies of mechanisms have focused exclusively on rumination and proximal minority stressors (e.g., internalized stigma). This limits our understanding of other potential mechanisms, such as decreases in the use of reappraisal and reflection, strategies associated with reducing anxious/depressed affect.

METHOD

We used data from a 30-day ecological momentary assessment study with 429 sexual minority women and gender diverse sexual minorities assigned female at birth to determine whether concurrent and prospective event-level associations between minority stress and anxious/depressed affect were mediated by changes in six emotion regulation strategies, perceived coping efficacy, and proximal stressors.

RESULTS

In partially lagged analyses, when individuals experienced enacted or internalized stigma, they reported increased rumination and expressive suppression on the same day, which predicted increases in anxious/depressed affect into the next day. Decreases in reappraisal also mediated partially lagged associations between internalized stigma and anxious/depressed affect. Fully lagged mediation was only demonstrated for rumination as a mechanism linking internalized stigma with anxious/depressed affect. We found concurrent evidence for other mechanisms (i.e., perceived coping efficacy, reflection, internalized stigma, and rejection sensitivity).

CONCLUSIONS

Results provided support for the roles of rumination and expressive suppression as mechanisms of linking minority stress and anxious/depressed affect. The concurrent evidence for other mechanisms suggests that future research with more temporal resolution is necessary to determine the temporality and directionality of these associations.

Evaluating age-related disparities in cannabis-related problems among LGBT+ versus non-LGBT+ adults

LGBT+ adults demonstrate greater cannabis-related problems (e.g., Cannabis Use Disorder [CUD]) compared to non-LGBT+ counterparts. No study has explored age-related disparities in cannabis problems across the adult lifespan, nor have studies identified specific CUD criteria that contribute to elevated CUD among LGBT+ adults. The purpose of this study was to examine associations between LGBT+ identity and age with endorsement of CUD criteria in a sample of regular cannabis consumers. An online sample of N = 4334 (25.1% LGBT+) adults aged 18-64 residing in the U.S. completed an online survey about cannabis use behaviors and CUD diagnostic criteria. Bivariate contrasts revealed significantly greater CUD criteria endorsement among LGBT+ respondents, largely driven by differences at younger ages. However, this effect disappeared in the majority of adjusted logistic regression models. LGBT+ identity was associated with greater probability of use in larger amounts (adjOR = 2.10, 95% CI: 1.22-3.60) and use despite physical/mental health problems (adjOR = 2.51, 95% CI:1.23-5.03). No age*LGBT+ identity interactions were detected. Plotted trends depict more pronounced disparities in outcomes among LGBT+ adults under 35 years. Several potential risk and protective factors including employment, education, and reasons for use were identified. There were age-related differences in these characteristics among LGBT+ and non-LGBT+ respondents. Initial findings highlight the need for LGBT+ research examining trends in health outcomes and sociodemographic and cannabis characteristics across the lifespan. The study also provides a substantive contribution regarding specific cannabis-related problems that young LGBT+ cannabis consumers may be more likely to endorse than their non-LGBT+ counterparts.

Recency of Cannabis Vaping in Sexual Minorities in Wave 5 of the Population Assessment of Tobacco and Health (PATH) Study

BACKGROUND

Cannabis vaping is increasing in the United States. Among populations at-risk are sexual minorities (SM) who are more likely to vape cannabis compared to their heterosexual counterparts. Cannabis vaping has been associated with negative health outcomes and concomitant use of other substances with increased risk with more recent use.

OBJECTIVES

This study examined the association between SM identification and recency of cannabis vaping (the last occasion that a participant used their vape device with cannabis) and number of puffs (the count of puffs that the participant took during their most recent use of their vape device with cannabis) using Wave 5 of the Population Assessment of Tobacco and Health (PATH) Study.

RESULTS

In a weighted sample of participants who reported ever vaping cannabis (N = 5,331), 15% identified as SM, about 60% vaped cannabis in the past 3 or more days, and the mean number of puffs was 2 (SE = 0.17). Using multinomial logistic regression and zero-inflated negative binomial regression, the results showed that compared to heterosexual adults who reported not recently vaping cannabis, SM had higher probabilities of vaping cannabis in the past 3 or more days, 1-2 days, and the day of interview.

CONCLUSION

SM individuals were more likely to recently vape cannabis, placing them at higher risk for respiratory diseases and use of other substances. Public health researchers and practitioners need to identify reasons for cannabis vaping in this population and implement targeted public health messaging to inform SM communities of the potential health effects of cannabis vaping.
