Substance Use as a Mechanism for Social Inclusion among Gay, Bisexual, and Other Men Who Have Sex with Men in Vancouver, Canada

Implementation opportunities and challenges to piloting a community-based drug-checking intervention for sexual and gender minority men in Vancouver, Canada: a qualitative study

BACKGROUND

In response to the overdose crisis, a collaborative group of two community-based organizations, a health authority and a research institute in Vancouver, Canada, implemented a pilot community-based drug checking (CBDC) intervention for sexual and gender minority (SGM) men. This study identified key factors that influenced the implementation of the CBDC intervention, including opportunities and challenges.

METHODS

We conducted semi-structured interviews with seven pertinent parties involved in the CBDC, including policymakers, researchers and representatives from community-based organizations. These interviews were coded and analyzed using domains and constructs of the Consolidated Framework for Implementation Research.

RESULTS

While drug-related stigma was identified as a challenge to deliver drug checking services, participants described the context of the overdose crisis as a key facilitator to engage collaboration between relevant organizations (e.g., health authorities, medical health officers, community organizations) to design, resource and implement the CBDC intervention. The implementation of the CBDC intervention was also influenced by SGM-specific needs and resources (e.g., lack of information about the drug supply). The high level of interest of SGM organizations in providing harm reduction services combined with the need to expand drug checking into community spaces represented two key opportunities for the CBDC intervention. Here, SGM organizations were recognized as valued partners that fostered a broader culture of harm reduction. Participants' emphasis that knowing the composition of one's drugs is a "right to know", particularly in the context of a highly contaminated illicit drug market, emerged as a key implementation factor. Lastly, participants emphasized the importance of involving SGM community groups at all stages of the implementation process to ensure that the CBDC intervention is appropriately tailored to SGM men.

CONCLUSIONS

The context of the overdose crisis and the involvement of SGM organizations were key facilitators to the implementation of a drug checking intervention in SGM community spaces. This study offers contextualized understandings about how SGM knowledge and experiences can contribute to implement tailored drug checking interventions.

Racial/Ethnic Disparities in Club Drug Use, Situational Club Drug Use during Sex, and Sexual Risk Behaviors among Alcohol-Using Men Who Have Sex with Men (MSM) in San Francisco

BACKGROUND

Club drug use-including 3,4-Methylenedioxymethamphetamine, ketamine, crack/cocaine, hallucinogens, gamma hydroxybutyrate, volatile nitrites, and methamphetamine-has been linked to sexual risk behaviors among MSM. Few studies examine how the use of club drugs and the association between club drug use during sex and sexual risk may differ by race/ethnicity.

METHODS

Using data from a cross-sectional study among alcohol-using MSM in San Francisco (n = 252), we examined the associations between the interaction of race/ethnicity and club drug use during sex, and the following behavioral outcomes: any condomless anal intercourse (CAI), insertive CAI, receptive CAI, and any serodiscordant sex in the past six months. All models controlled for income, HIV status, relationship status, age, and current use of a biomedical HIV prevention tool (i.e., Pre-Exposure Prophylaxis [PrEP] or antiretroviral therapy).

RESULTS

There were significant racial differences in club drug use (p < 0.001) and club drug use during sex (p = 0.01). Asian/Pacific Islander (API) and Latino participants reported using club drugs the most at 78.8% and 79%, respectively. Among users of club drugs, club drug use during sex was most common among Black (100%), and Latino MSM (93%). Significant interactions between race/ethnicity and club drug use during sex were observed for CAI (p = 0.02), insertive CAI (p = 0.01), and receptive CAI (p = 0.01). API participants who used club drug during sex had higher odds of reporting CAI (aOR = 15.27, CI = 1.50-155.34), insertive CAI (aOR = 21.11, CI = 2.04-218.10), and receptive CAI (aOR = 21.11, CI = 2.04-218.10).

CONCLUSIONS

Given the differing rates of club drug use during sex by race/ethnicity and the role race/ethnicity plays in modifying the relationships between club drug use during sex and sexual risk behaviors, culturally-tailored interventions may be needed to address the needs of ethnically-diverse, club drug-using MSM.

Attitudes of Gay, Bisexual, and Other Men Who Have Sex with Men (GBM) toward Their Use of Amphetamine-Type Stimulants and Relation to Reducing Use in Three Canadian Cities

BACKGROUND

We explored attitudes of gay, bisexual, and other men who have sex with men (GBM) toward their amphetamine-use and associations with reduced use over time.

METHODS

We recruited sexually-active GBM aged 16+ years in Montreal, Toronto, and Vancouver, Canada, from 02-2017 to 08-2019, with follow-up visits every 6-12 months until November 2020. Among participants who reported past-six-month (P6M) amphetamine-use at enrollment, we used logistic regression to identify demographic, psychological, social, mental health, other substance-use, and behavioral factors associated with reporting needing help reducing their substance-use. We used mixed-effects logistic regression to model reduced P6M amphetamine-use with perceived problematic-use as our primary explanatory variable.

RESULTS

We enrolled 2,449 GBM across sites. 15.5-24.7% reported P6M amphetamine-use at enrollment and 82.6 - 85.7% reported needing no help or only a little help in reducing their substance use. Reporting needing a lot/of help or completely needing help in reducing substance-use was associated with group sex participation (AOR = 2.35, 95%CI:1.25-4.44), greater anxiety symptomatology (AOR = 2.11, 95%CI:1.16-3.83), greater financial strain (AOR = 1.35, 95%CI:1.21-1.50), and greater Escape Motive scores (AOR = 1.07, 95%CI:1.03-1.10). Reductions in P6M amphetamine-use were less likely among GBM who perceived their amphetamine-use as problematic (AOR = 0.17 95% CI 0.10 - 0.29).

CONCLUSIONS

Most amphetamine-using GBM did not feel they needed help reducing their substance use, and many reported reduced amphetamine-use at subsequent visits. Those who perceived their use as problematic were less likely to reduce their use. Further interventions to assist GBM in reducing their use are needed to assist those who perceive their use as problematic.

Characterizing Social Connectedness and Associated Mental Health Symptoms among Sexual Minority Men Enrolled in a Substance Use Recovery Support Program

BACKGROUND

Sexual minority men (SMM; gay, bisexual, and other men who have sex with men) report higher rates of substance use compared to other populations. Social connectedness is a critical component for promoting and maintaining recovery from substance use disorders. However, the degree of social connectedness among SMM who report substance use is largely unknown.

OBJECTIVES

We examined substance use, social connectedness (past 30-d participation in formal recovery support, past 30-d interaction with supportive family/friends, relationship satisfaction, and types of support) and mental health among SMM at the time of their enrollment in a behavioral substance use program from September 2019 to October 2021.

RESULTS

Of the107 SMM, 80% of the sample reported past 30-d illicit substance use, with methamphetamine representing the most commonly reported drug used (53%). Participants used a variety of social connections for support, including self-help groups (44% voluntary; 5% religious-affiliated; 20% other) and family/friends (81%). Importantly, 15% reported they had no one to turn to when having trouble and 36% were either dissatisfied or very dissatisfied with their relationships. Participants who endorsed significant depressive (58%) and anxiety (70%) symptoms were more likely to endorse relationship dissatisfaction than participants who did not endorse symptoms (p < 0.01).

CONCLUSIONS

One-third of SMM enrolled in a substance use recovery program expressed relationship dissatisfaction, particularly those struggling with depression or anxiety. Future research and programming should examine ways of leveraging existing social connectedness or forging new social supports to enhance mental health and substance use recovery for SMM using substances.

Gender, sexual orientation identity, and initiation of amphetamine injecting among people who inject drugs: Examination of an expanding drug era in Montreal, Canada, 2011-19

BACKGROUND

Amphetamine injection is expanding in North America and has been associated with male homosexuality among people who inject drugs (PWID). Applying subcultural evolution theory, we examined overall and gender-stratified trends in amphetamine injection and assessed sexual orientation as a gender-specific predictor of initiation among PWID in Montreal, Canada.

METHODS

Data were from HEPCO, an open prospective cohort of PWID. Gender and sexual orientation were self-identified at enrolment. Interviewer-administered questionnaires at three-monthly (HCV RNA-negative participants) or yearly (RNA-positive) intervals captured past three-month amphetamine injection and covariates. Annual prevalence and linear trends in amphetamine injection were estimated using GEE. Incidence was computed among naïve individuals and hazard ratios for initiation estimated using gender-stratified, time-varying Cox regression models.

RESULTS

803 participants contributed 8096 observations between March 2011 and December 2019. Annual prevalence of amphetamine injecting increased from 3.25% [95%CI: 2.06-4.43%] to 12.7% [9.50-16.0] (trend p<0.001). Bivariate Cox regression models suggested similar and divergent predictors of initiation by gender. Incidence was 3.27 per 100 person-years [95%CI: 2.51-4.18] among heterosexual men, 7.18 [3.50-13.2] among gay/bisexual men, 1.93 [0.78-4.02] among heterosexual women and 5.30 [1.69-12.8] among gay/bisexual women. Among men, gay/bisexual identity doubled risk of initiation after adjusting for age, ethnicity, calendar year (aHR 2.16 [1.07-4.36]) and additional covariates (2.56 [1.24-5.30]). Among women, evidence for an association with gay/bisexual identity was inconclusive (aHR 2.63 [0.62-11.2]) and sample size precluded further adjustment CONCLUSIONS: Prevalence of amphetamine injection among PWID increased four-fold from 2011 to 2019, with elevated risk of initiation in gay and bisexual men.

Comparing Factors Associated with Increased Stimulant Use in Relation to HIV Status Using a Machine Learning and Prediction Modeling Approach

Stimulant use is an important driver of HIV/STI transmission among men who have sex with men (MSM). Evaluating factors associated with increased stimulant use is critical to inform HIV prevention programming efforts. This study seeks to use machine learning variable selection techniques to determine characteristics associated with increased stimulant use and whether these factors differ by HIV status. Data from a longitudinal cohort of predominantly Black/Latinx MSM in Los Angeles, CA was used. Every 6 months from 8/2014-12/2020, participants underwent STI testing and completed surveys evaluating the following: demographics, substance use, sexual risk behaviors, and last partnership characteristics. Least absolute shrinkage and selection operator (lasso) was used to select variables and create predictive models for an interval increase in self-reported stimulant use across study visits. Mixed-effects logistic regression was then used to describe associations between selected variables and the same outcome. Models were also stratified based on HIV status to evaluate differences in predictors associated with increased stimulant use. Among 2095 study visits from 467 MSM, increased stimulant use was reported at 20.9% (n = 438) visits. Increased stimulant use was positively associated with unstable housing (adjusted [a]OR 1.81; 95% CI 1.27-2.57), STI diagnosis (1.59; 1.14-2.21), transactional sex (2.30; 1.60-3.30), and last partner stimulant use (2.21; 1.62-3.00). Among MSM living with HIV, increased stimulant use was associated with binge drinking, vaping/cigarette use (aOR 1.99; 95% CI 1.36-2.92), and regular use of poppers (2.28; 1.38-3.76). Among HIV-negative MSM, increased stimulant use was associated with participating in group sex while intoxicated (aOR 1.81; 95% CI 1.04-3.18), transactional sex (2.53; 1.40-2.55), and last partner injection drug use (1.96; 1.02-3.74). Our findings demonstrate that lasso can be a useful tool for variable selection and creation of predictive models. These results indicate that risk behaviors associated with increased stimulant use may differ based on HIV status and suggest that co-substance use and partnership contexts should be considered in the development of HIV prevention/treatment interventions.

Considerations and recommendations for mHealth interventions for substance use among Sexual and Gender Minority (SGM) individuals: A narrative review of the past 5 years

Purposeof Review

The prevalence of problematic substance use is disproportionately higher among sexual and gender minority (SGM) adults compared to adults in the general population. mHealth as a treatment modality could reduce barriers to accessing substance use treatments among SGM populations. Through a qualitative literature search, the current narrative review aimed to understand the lived experiences of SGM individuals who use substances and to synthesize recommendations made in the literature to inform future mHealth interventions.

Recent Findings

Positive and negative reinforcement motives were prominent reasons for substance use, which included SGM identity expression and conformity motives. Individual- and system-level treatment barriers included a lack of safe and nonjudgmental environment, shame and stigma, and limited knowledge about treatment options. Barriers were directly linked to the reported substance use treatment needs in this population.

Summary

On-demand app features, real-time intervention and assessment, and anonymity should be considered in future mHealth trials.

Patterns of Event-Level Concurrent Substance Use During Sex Among Gay, Bisexual, and Other Men Who Have Sex with Men in Metro Vancouver

This study identified patterns of sexualized substance use among gay, bisexual, and other men who have sex with men (gbMSM) and examined associated risk factors for sexually transmitted and blood borne infections (STBBI). Data were from a longitudinal cohort recruited using respondent-driven sampling between Feb-2017 and Feb-2019. Participants reported on events with up to five of their most recent sexual partners. Latent class analysis examined patterns of concurrent substance use 2 h prior to or during sex. Multinomial regression identified demographic, partner-level, and event-level factors associated across 11,877 sexual events reported by 757 participants. Most combinations of substance use were rare, but most drugs were frequently combined with other drugs when they were used prior to or during a sexual event. Six latent classes of concurrent event-level substance use were identified. The referent class (58.8% of events) was characterized by limited use of any drugs. The Common Drug Use class (12.1%) was characterized by use of alcohol, cannabis, and poppers and the Licit Drug Use class (21.6%) was characterized by use of alcohol alone. The Party 'N' Play (PnP) class (2.3%) was characterized by use of crystal methamphetamine GHB, Poppers, and Erectile Drugs; The Multi-use (3.5%) class was characterized by the PnP substances plus alcohol and ecstasy; and the Cannabis + class was characterized by use of Cannabis, Erectile Drugs, and Ecstasy. Relative to the referent class, all other classes were associated with events with more behavioural and network risk factors for STBBIs-highlighting the need for harm reduction interventions for gbMSM who use these drugs.

Chemsex and incidence of sexually transmitted infections among Canadian pre-exposure prophylaxis (PrEP) users in the l'Actuel PrEP Cohort (2013-2020)

OBJECTIVES

Use of illicit substances during sex (chemsex) may increase transmission of HIV and other STIs. Pre-exposure prophylaxis (PrEP) is highly effective at preventing HIV transmission, providing an important prevention tool for those who practise chemsex. However, it does not prevent acquisition of other STIs. We aim to examine the impact of chemsex on STI incidence among gay, bisexual and other men who have sex with men (gbMSM), and transgender women using PrEP in Montréal, Canada.

METHODS

We linked baseline sociodemographic and behavioural data with follow-up STI testing from 2013 to 2020 among PrEP users in the l'Actuel PrEP Cohort (Canada). Focusing on the 24 months following PrEP initiation, we estimated the effect of chemsex reported at baseline on cumulative incidence of gonorrhoea and chlamydia using Kaplan-Meier curves and survival analyses. We investigated the role of polysubstance use and effect modification by sociodemographic factors.

RESULTS

There were 2086 clients (2079 cisgender gbMSM, 3 transgender gbMSM, 4 transgender women) who initiated PrEP, contributing 1477 years of follow-up. There were no incident HIV infections among clients on PrEP. Controlling for sociodemographic confounders, clients reporting chemsex at baseline had a 32% higher hazard of gonorrhoea/chlamydia diagnosis (adjusted HR=1.32; 95% CI: 1.10 to 1.57), equivalent to a risk increase of 8.9 percentage points (95% CI: 8.5 to 9.4) at 12 months. The effect was greater for clients who reported polysubstance use (adjusted HR=1.51; 95% CI: 1.21 to 1.89). The strength of the effect of chemsex on STI incidence varied by age, education and income.

CONCLUSION

Among PrEP users, chemsex at baseline was linked to increased incidence of gonorrhoea and chlamydia. This effect was stronger for people reporting multiple chemsex substances. The high STI incidence among gbMSM who report chemsex highlights the importance of PrEP for this population and the need for integrated services that address the complexities of sexualised substance use.

"White, Tall, Top, Masculine, Muscular": Narratives of Intracommunity Stigma in Young Sexual Minority Men's Experience on Mobile Apps

What forms of intracommunity stigma do young sexual minority men narrate as they participate in communities through mobile apps? In a content analysis of 32 interviews with a racially diverse sample of young sexual minority men (ages 19-25; 84.4% non-White) from four regions of the USA, a majority of men (62.5%) spontaneously discussed mobile apps (e.g., Grindr, Scruff) when asked about their experience of community more broadly. Men's narratives revealed engagement with intracommunity stigma related to body size, race/ethnicity, gender expression, and sexual position (e.g., bottom). Stigma related to HIV status, substance use, and social class were not spontaneously narrated in response to questions about men's experience in communities. Expressions of stigma were frequently experienced intersectionally, particularly regarding racialized stereotype expectations (e.g., "Asian men are twinks, effeminate"). We discuss the ways in which sexual minority men reproduce dominant ideologies related to racism, misogyny, and masculine body ideals as they engage with one another on mobile apps. To the extent that many young men rely on mobile apps for community connection, their experiences of community might serve to exacerbate, rather than ameliorate, the deleterious impact of stigma.

Risk Behaviors Associated with Patterns of Sexualized Stimulant and Alcohol Use among Men Who Have Sex with Men: a Latent Class Analysis

Substance use during sexual encounters (sexualized substance use) is an important driver of HIV and sexually transmitted infection (STI) disparities that are experienced by men who have sex with men (MSM). This analysis aimed to identify patterns of sexualized substance use and their associations with HIV risk behaviors. We utilized visit-level data from a longitudinal cohort of predominantly Black/Latinx MSM, half with HIV and half with substance use in Los Angeles, California. Every 6 months from 8/2014 to 3/2020, participants underwent STI testing and completed surveys on demographics, sexualized substance use (stimulant and/or alcohol intoxication during oral sex, receptive anal intercourse [RAI] and/or insertive anal intercourse [IAI]), transactional sex, biomedical HIV prevention (pre-/post-exposure prophylaxis use or undetectable viral load), and depressive symptoms. Latent class analysis was used to identify patterns of sexualized substance use. Multinomial logit models evaluated risk behaviors associated with latent classes. Among 2386 study visits from 540 participants, 5 classes were identified: no substance use, sexualized stimulant use, sexualized alcohol use, sexualized stimulant and alcohol use, and stimulant/alcohol use during oral sex and RAI. Compared to the no sexualized substance use class, sexualized stimulant use was associated with transactional sex, current diagnosis of STIs, not using HIV biomedical prevention, and depressive symptoms. Sexualized alcohol use had fewer associations with HIV risk behaviors. Patterns of sexual activities, and the substances that are used during those activities, confer different risk behavior profiles for HIV/STI transmission and demonstrate the potential utility of interventions that combine substance use treatment with HIV prevention.

"It's how we get to know each other": Substance use, connectedness, and sexual activity among men who have sex with men who are living with HIV

BACKGROUND

Among MSM, substance use increases risk for acquiring HIV and is associated with sub-optimal engagement in HIV-related care. Most research related to substance use and sexual activity among MSM focuses on identifying and reducing risk of HIV acquisition and transmission rather than pleasure and agency. However, substance use may also facilitate sexual pleasure and build community, which could be particularly meaningful for individuals who cope with intersecting stigmas related to the disease, sexual identity, and drug use.

METHODS

To explore the ways in which substance use both promotes and hinders positive sexual expression and healthy sexual relationships, we conducted a secondary analysis of 33 semi-structured qualitative interviews with MSM living with HIV who were poorly engaged in care and reported recent substance use.

RESULTS

Thematic analysis revealed that substance use was perceived as: (1) a potential pathway to intimacy and enhanced sexual experiences; (2) a tool to help access partners and gain entry to a community; and (3) a source of empowerment, though some noted that it sometimes came at the cost of sexual disempowerment and unbalanced relationships.

CONCLUSIONS

Clinically, our results suggest that the complex motivations for substance use during sexual activity need to be carefully considered and discussed with patients, especially when attempting to decrease problematic use as a pathway to improved HIV self-care.

Factors associated with chemsex in Portugal during the COVID-19 pandemic

Objective:

to investigate the factors associated with the practice of sex under the influence of drugs (chemsex) among Portuguese men who have sex with men during the period of social distancing to prevent the COVID-19.

Method:

online survey applied in May 2020 to a sample of 1,301 participants living in Portugal, recruited according to Respondent Driven Sampling and via social media Facebook^®. Descriptive and bivariate analyses were performed along with logistic regression to calculate adjusted Odds Ratio (ORa).

Results:

the prevalence of chemsex was 20.2%. The likelihood of practicing chemsex increased with group sex (ORa: 28.4, 95%CI 16.93–47.49); unprotected sex (ORa: 7.1 95%CI 4.57–10.99); the use of pre-exposure prophylaxis (PrEP) to prevent COVID-19 (ORa: 4.2, 95%CI 2.71–6.39) and COVID-19 testing (ORa: 1.9, 95%CI 1.15–3.10).

Conclusion:

the practice of chemsex among men who have sex with men during the COVID-19 pandemic in Portugal was very frequent and may support greater understanding of the role and impact of sexual behavior on the COVID-19 transmission rates and the current pandemic situation in Portugal.

Experimental (Re)structuring: The Clinical Trial as Turning Point Among Medical Research Participants

Amid the growth of addiction medicine randomized controlled trials (RCTs), scholars have begun examining participants' study experiences, highlighting facilitators and barriers to enrollment. However, this work can overlook the interplay between trial participation and social-structural dimensions among people with substance use disorders linked to the social nature of use, socioeconomic marginalization, and time demands of substance procurement and use. To effectively conduct RCTs with this unique population, it is necessary to examine the broader social context of study participation. We conducted nested qualitative interviews with 22 participants involved in an RCT testing a treatment for alcohol and opioid use disorders in HIV clinics. Thematic analyses revealed social-structural circumstances shaping RCT participation as well as how participation constitutes a turning point, prompting individuals to reconfigure social networks, reorient to spatial environments, and reorganize day-to-day life-with implications for how substance use disorder RCTs should be approached by researchers.

‘I was just doing what a normal gay man would do, right?’: The biopolitics of substance use and the mental health of sexual minority men

Drawing on 24 interviews conducted with gay, bisexual, queer and other men who have sex with men (GBM) living in Toronto, Canada, we examined how they are making sense of the relationship between their mental health and substance use. We draw from the literature on the biopolitics of substance use to document how GBM self-regulate and use alcohol and other drugs (AODC) as technologies of the self. Despite cultural understandings of substance use as integral to GBM communities and subjectivity, GBM can be ambivalent about their AODC. Participants discussed taking substances positively as a therapeutic mental health aid and negatively as being corrosive to their mental wellbeing. A fine line was communicated between substance use being self-productive or self-destructive. Some discussed having made ‘problematic’ or ‘unhealthy’ drug-taking decisions, while others presented themselves as self-controlled, responsible neoliberal actors doing ‘what a normal gay man would do’. This ambivalence is related to the polarizing binary community and scientific discourses on substances (i.e. addiction/healthy use, irrational/rational, uncontrolled/controlled). Our findings add to the critical drug literature by demonstrating how reifying and/or dismantling the coherency of such substance use binaries can serve as a biopolitical site for some GBM to construct their identities and demonstrate healthy, ‘responsible’ subjectivity.

Use of "Poppers" among Adults in the United States, 2015-2017

We sought to estimate the prevalence as well as demographic and drug use-related correlates of poppers use among adults in the United States. Data were analyzed from adult participants (ages 18-64) in the 2015-2017 National Survey on Drug Use and Health (N = 115,744), a nationally representative survey of non-institutionalized adults in the US. An estimated 3.3% of adults have ever used poppers. Over a third (35.1%) of gay men are estimated as having ever used poppers. Estimates were lower for heterosexual (3.7%) and bisexual males (11.3%), and for heterosexual (1.8%), bisexual (4.8%), and lesbian women (6.3%). In the multivariable model, compared to male heterosexuals, gay men were at increased odds for reporting lifetime popper use (aOR = 24.64, p<.001), and bisexual men (aOR = 3.55, p <.001), lesbian women (aOR = 1.86, p =.010), and bisexual women (aOR = 1.33, p =.049) were at increased odds for lifetime use. Having a college degree was associated with increased odds for use, and lifetime use of marijuana, ecstasy/MDMA/Molly, cocaine, LSD, methamphetamine, tranquilizers, and/or opioids were associated with higher odds for use. Gay men in particular are at high risk for use. Results can help inform prevention efforts, particularly in sexual minority populations.
