J Int AIDS Soc 2024; 27:e26323. [PMID: 38982574 PMCID: PMC11233270 DOI: 10.1002/jia2.26323] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Accepted: 06/10/2024] [Indexed: 07/11/2024] Open
Abstract
INTRODUCTION Chemsex, the use of psychotropic drugs before or during sexual intercourse, is associated with various HIV risk factors, including condomless sex and reduced adherence to pre-exposure prophylaxis or antiretroviral therapy (ART). In the Philippines, there are still limited studies exploring the associations between chemsex, HIV status and ART adherence. This study aims to compare recent and lifetime chemsex engagement in association with self-reported HIV status among Filipino men who have sex with men (MSM). We further explored the association between chemsex and ART adherence among people living with HIV engaged in chemsex. METHODS A cross-sectional online survey of 479 Filipino MSM was conducted from 3 August to 1 December 2019. Demographic profiles, sexual behaviours, drug use, history of sexually transmitted infections (STIs), chemsex engagement and HIV status were collected and analysed. Bivariable and multivariable logistic regression were employed to assess the association between self-reported HIV status and chemsex engagement. RESULTS Among the 479 respondents, Filipino MSM engaged in drug use and chemsex were generally older compared to those not engaged in drug use and chemsex (average age 31-33 vs. 29 years old; p<0.05). Methamphetamine was the most common drug for people who reported using drugs. An HIV-positive status was associated with recent chemsex engagement (aOR = 5.18, p<0.05) and a history of STIs (aOR = 2.09, p<0.05). The subgroup analysis showed that 79% (166/200) of persons living with HIV were adherent to ART. There was no significant association found between chemsex and ART adherence in the logistic regression analyses. CONCLUSIONS Chemsex behaviour, particularly recent chemsex engagement, is significantly associated with self-reported HIV status. The emerging data on MSM engaged in chemsex require integration of a more person-centred, comprehensive and robust harm reduction programmes into the existing combination prevention strategies in the country. Health education for Filipino MSM engaged in chemsex should prioritize raising awareness about methamphetamine effects and overdose risks, alongside proper medical management.

Lodge W, Kelly PJA, Napoleon S, Plezia S, Mimiaga MJ, Biello KB. Prevalence of methamphetamine use among gay, bisexual and other men who have sex with men: A systematic review and meta-analysis. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2024; 123:104271. [PMID: 38061224 DOI: 10.1016/j.drugpo.2023.104271] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Revised: 11/09/2023] [Accepted: 11/16/2023] [Indexed: 01/17/2024]
Abstract
BACKGROUND International efforts have reduced the availability of methamphetamine precursors, but its distribution and use continue to rise. Methamphetamine use can lead to short- and long-term adverse effects, including addiction, physical and psychosocial health problems, socioeconomic troubles, incarceration, overdose, and death. Gay, bisexual, and other men who have sex with men (MSM) have been shown to have an elevated prevalence of methamphetamine use. METHODS We conducted a systematic review and meta-analysis to estimate the prevalence of methamphetamine use among MSM. We searched electronic databases, such as PubMed, for peer-reviewed literature published between 2011 and 2022. Data on methamphetamine use were extracted, including study features, location, study design, sampling method, recruitment period, specific MSM subgroups, prevalence period, and demographics. Employing a random-effects model, we computed the pooled prevalence of methamphetamine use among MSM across two prevalence periods: recent use (i.e., one month, three months, six months, one year) and lifetime use. RESULTS The systematic review included 56 studies with a total of 25,953 MSM who use methamphetamine. Most studies were conducted in Europe, with the highest prevalence reported in the United Kingdom. The studies primarily used cross-sectional or cohort study designs with convenience sampling. The pooled prevalence rates across recent use (i.e., past month, past three months, past six months, and past year) was 15% (95% CI [11-19%]). Additionally, we pooled lifetime use, which was 23% (95% CI [9-38%]). High heterogeneity (I2 > 99%) was observed, indicating significant variation. CONCLUSION This systematic review and meta-analysis provide a pooled prevalence of methamphetamine use among MSM. The analysis accounts for study design, prevalence period, specific MSM subgroups, and geographical areas to estimate methamphetamine use in diverse settings and populations. The review highlights the need for targeted interventions and harm reduction strategies focused on prevention, education, healthcare access, and stakeholder collaboration to address the multifaceted challenges of methamphetamine use among MSM.

THE INTERNATIONAL JOURNAL OF DRUG POLICY 2022; 110:103879. [PMID: 36265327 PMCID: PMC9886012 DOI: 10.1016/j.drugpo.2022.103879] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2022] [Revised: 09/21/2022] [Accepted: 09/30/2022] [Indexed: 11/05/2022]
Abstract
BACKGROUND Crystal methamphetamine use has substantially increased among people who use opioids in recent years, yet the impact of opioid agonist therapy (OAT) on crystal methamphetamine use remains poorly characterized. Therefore, we sought to examine the relationship between OAT engagement and crystal methamphetamine use and to assess if this relationship differs according to the ongoing use of unregulated opioids. METHODS Data was collected from two harmonized ongoing prospective cohorts of people who use drugs in Vancouver, Canada, between December 2005 and March 2020. We employed multivariable generalized estimating equations to study the relationship between OAT engagement and crystal meth use stratified by ongoing unregulated opioid use. RESULTS Of 1742 participants who reported frequent opioid use at baseline, the median age was 42 years, and 61.3% were male. Multivariable analyses showed that compared to those who had not received OAT for at least one year: in the absence of ongoing unregulated opioid use, individuals who recently discontinued (adjusted Odds Ratio [aOR] = 0.47, 95% CI = 0.27-0.79), newly initiated (aOR = 0.52, 95% CI = 0.31-0.89), or were retained on OAT (aOR = 0.48, 95% CI = 0.31-0.72) reported a lower frequency of crystal methamphetamine use; in the presence of ongoing unregulated opioid use, individuals who newly initiated OAT reported a greater crystal methamphetamine use frequency (aOR = 1.24, 95% CI = 1.02-1.51). CONCLUSIONS We demonstrated a differential relationship between OAT engagement and crystal methamphetamine use that was conditional on the ongoing use of unregulated opioids. Our findings highlight the complexity of OAT implementation and suggest that polysubstance use patterns should be an important consideration for care providers when devising comprehensive treatment strategies and prognosticating treatment effects.

Event-level patterns of methamphetamine and poly-drug use among millennial sexual minority men: The P18 Cohort Study. Addict Behav 2021; 117:106831. [PMID: 33588290 DOI: 10.1016/j.addbeh.2021.106831] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2020] [Revised: 01/08/2021] [Accepted: 01/09/2021] [Indexed: 11/23/2022]
Abstract
INTRODUCTION Knowledge on methamphetamine use among a new generation of sexual minority men (SMM) is limited. This study describes the event-level patterns of methamphetamine use and characteristics of methamphetamine users across time among Millennial SMM emerging into adulthood. METHODS A prospective cohort study was conducted in two waves: 2009-2014 (Wave I) and 2014-2019 (Wave II) in the New York City metropolitan area. A total of 600 Millennial SMM ages 18-19 years were recruited for Wave I. A total of 665 SMM ages 22-23 years were recruited for Wave II, of which 41.2% (n = 274) were retained from Wave I. The Timeline Followback assessment was conducted every six months to record event-level drug use in the 30 days prior to the visit. RESULTS A total of 5.4% of participants of between the ages of 18-27 reported methamphetamine use throughout the study period. The average number of days of methamphetamine use was significantly higher among racial/ethnic minority men in Wave II (F = 4.34, p = 0.0029). We found methamphetamine use occurred more often on weekend days and same-day use of methamphetamine occurred most often with cannabis and gamma-hydroxybutyrate. Usage of methamphetamine was significantly greater among SMM in Wave II who by design were older than Wave I. CONCLUSION We have identified differences in methamphetamine use by race/ethnicity. Weekend use and poly-drug use were common among methamphetamine-using SMM. Data indicate differential use in the population and that attempts to address this addictive behavior must be linked to other drug use and socialization among young SMM.

The Effects of Methamphetamine Use on the Sexual Lives of Gender and Sexually Diverse People in Dhaka, Bangladesh: A Qualitative Study. ARCHIVES OF SEXUAL BEHAVIOR 2021; 50:479-493. [PMID: 32239362 PMCID: PMC7529687 DOI: 10.1007/s10508-020-01674-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/03/2019] [Revised: 02/26/2020] [Accepted: 02/27/2020] [Indexed: 06/11/2023]
Abstract
Methamphetamine use has increased among gender and sexually diverse people in several countries, including Bangladesh. This study aimed to explore the effects of methamphetamine on the sexual lives of these people in Dhaka, Bangladesh. An exploratory qualitative study was conducted, comprising 30 in-depth interviews with gender and sexually diverse people including males having sex with males, male sex workers, and transgender women (hijra) under HIV intervention coverage. Ten key informant interviews were also conducted with individuals who have expertise in relevant disciplines such as drug use, harm reduction, and HIV and AIDS. Digitally recorded data were manually analyzed under the thematic analysis framework. Findings indicated that many participants reported that methamphetamine brought changes in their sexual lives such as increased sexual drive, engagement in group sex, the increased ability to perform serial sex, transactional sex, impulsive and coercive sex, initiation and switching of male-to-male sexual practices, and limited condom use. Key informants noted that there is a dearth of methamphetamine-related services in Bangladesh. Methamphetamine use was found to lead to diverse effects on the sexual lives of gender and sexually diverse people, thus making it a driving force for shaping sexual practices and, hence, sexual risks. Therefore, it is essential for policy-level stakeholders and program managers to consider the risks of methamphetamine use due to their negative ramifications on sexual health, including HIV risks.

Correlates and subgroups of injecting drug use in UK gay and bisexual men: Findings from the 2014 Gay Men's Sex Survey. Drug Alcohol Depend 2018; 187:292-295. [PMID: 29702337 DOI: 10.1016/j.drugalcdep.2018.03.014] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2017] [Revised: 02/20/2018] [Accepted: 03/11/2018] [Indexed: 11/20/2022]
Abstract
BACKGROUND Evidence to understand which gay and bisexual men (GBM) inject drugs remains scant, especially in the UK. We describe correlates of last-year injecting in UK GBM, and characterise subgroups of GBM who inject drugs by types of drugs used. METHODS Using data from the 2014 Gay Men's Sex Survey, an opportunistic internet-based survey conducted of GBM living in the UK, we examined via logistic regression correlates with any injecting of six drugs (amphetamine/speed, crystal methamphetamine, heroin, mephedrone, GHB/GBL, and ketamine) in the last year. We estimated latent class models to understand underlying subgroups of injecting drug use among GBM reporting injecting drug use in the last year. RESULTS Injecting was most common in GBM who were of middle age, who were HIV seropositive, and who lived in London, and was significantly associated with sexual risk with multiple partners in the last year, whether steady or non-steady. Most GBM who engaged in injecting either injected crystal methamphetamine, mephedrone or both (class 1, chemsex, 88.6% of injectors), whereas a smaller group had a focus on opiates (class 2, opiate, 7.9%). A small but identifiable subgroup (class 3, eclectic, 3.5%) engaged in injecting across the range of drugs examined. CONCLUSIONS This is the first epidemiological analysis to describe subgroups of injecting, and to describe correlates of injecting drug use, in UK GBM. Implications for design of harm reduction services include a need to focus on injecting drug use beyond opiates, currently the focus of most harm reduction services.

Abstract
BACKGROUND Sexualised drug use (SDU) refers to the use of drugs in a sexual context. This includes 'Chemsex'- the use of drugs (specifically crystal methamphetamine, GHB/GBL and mephedrone) before or during planned sexual activity to sustain, enhance, disinhibit or facilitate the experience. Here we aimed to synthesise available UK prevalence data for Chemsex, SDU and the use of Chemsex drugs in an undefined context (CDU) in men who have sex with men (MSM). METHODS Papers published between January 2007 and August 2017 reporting Chemsex, SDU and/or Chemsex drug use (CDU) prevalence in MSM were identified through PubMed. Citations were searched for further eligible publications. We also conducted a review of national surveillance data, extracting prevalence data for Chemsex, SDU or CDU. Synthesized data were then assessed to determine the time at which these drugs were taken, in this case just prior to or during sexual activity (event-level). RESULTS Our search identified 136 publications, of which 28 were included in the final data synthesis. Three of the four surveillance systems assessed provided SDU or CDU data in MSM. Few publications included event-level data for Chemsex (n = 4), with prevalence estimates ranging from 17% among MSM attending sexual health clinics (SHC) to 31% in HIV-positive MSM inpatients. Prevalence estimates for SDU (n = 7 publications) also varied considerably between 4% in MSM receiving HIV care to 41% among MSM attending SHC for HIV post-exposure prophylaxis (PEP). Eighteen publications provided data for CDU. CONCLUSION Prevalence estimates varied considerably due to differences in the definition used and population assessed. Standardised definitions and studies with representative national samples of MSM are required to improve our understanding of the extent of Chemsex and its associated risks. Longitudinal event-level data for SDU and Chemsex are needed to monitor impact of interventions.

Abstract
BACKGROUND Treatment as Prevention (TasP) leading to increased HIV treatment optimism among men who have sex with men (MSM) has been previously associated with behavioural risk compensation, though not yet via crystal methamphetamine (CM) use. Among HIV-negative MSM in a TasP environment, this study aimed to investigate the prevalence of recent CM use over time, examine the association between HIV treatment optimism and CM use and initiation, and identify correlates of recent CM use and predictors of CM initiation. METHODS Using data from a prospective behavioural cohort study of sexually active MSM in the Vancouver area, we used multi-level generalized mixed effect models to evaluate temporal trends in CM use, univariable and multivariable logistic regression to identify covariates of recent CM use, and univariable and multivariable survival analysis to identify predictors of CM initiation. RESULTS Of 497 HIV-negative cohort participants, 10.3% reported any recent CM use at enrollment. From 2012-2016, there were no statistically significant temporal trends in overall CM use or with routes of administration. In multivariable logistic regression analyses, HIV treatment optimism was not associated with recent CM use (not retained in final model) or CM initiation (aHR = 1.06, 95% CI:0.98-1.15). Significant correlates of CM use include recent gamma-hydroxybutyrate (GHB) and ecstasy use, and having received/given drugs for sex. CONCLUSIONS Among HIV-negative MSM in Vancouver, HIV treatment optimism does not appear to be independently associated with CM use or initiation of use, though use of CM was both prevalent and stable over time.

Abstract
BACKGROUND The term "chemsex" was coined to indicate the voluntary intake of psychoactive and non psychoactive drugs in the context of recreational settings to facilitate and/or to enhance sexual intercourses mostly among men who have sex with other men (MSM). OBJECTIVE The authors aimed to review the mechanisms of action, the toxicity and the pattern of use and abuse of substances involved in "chemsex" practice together with the sociocultural background underlying it and the health-related consequences that they may have. RESULTS Gamma-hydroxybutyrate, gamma-butyrolactone,1,4-butanediol, mephedrone, methamphetamine, sildenafil, tadalafil, vardenafil and alkyl nitrites have been described in their role of "chemsex drugs" including pharmacological action and in their implication to impair capacities to chose sexual partners and consensual sex. Moreover, it has been demonstrated that sexual activity over protracted length of time under the influence of chemsex drugs can result in rectal trauma or penile abrasions and a significant increase of the risk of transmission of sexual transmitted diseases, especially in case of condomless intercourses, which are frequent in this context, representing therefore a serious health threat. CONCLUSION One of the major problems to establish health policy priority interventions for chemsex is the lack of available epidemiological data on the issue. Finally, social actions should be taken in order to break down the barriers that currently exist among chemsex drug users in accessing services, including the shame and stigma often associated with drug use. In conclusion, more specific resources to face high risks of infections and HIV transmission are required in bisexual and homosexual individuals having SUID: sex under the influence of drugs.

THE INTERNATIONAL JOURNAL OF DRUG POLICY 2016; 38:29-35. [PMID: 27842251 DOI: 10.1016/j.drugpo.2016.10.007] [Citation(s) in RCA: 75] [Impact Index Per Article: 9.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2016] [Revised: 10/03/2016] [Accepted: 10/19/2016] [Indexed: 11/28/2022]
Abstract
BACKGROUND 'Chemsex' refers to the combining of sex and illicit drugs, typically mephedrone, GHB/GBL, and crystal methamphetamine. While numerous studies have examined the role of illicit drugs in sexual risk taking, less attention has been paid to the broader social context and structures of their use among gay men. Given their established role in influencing health related behaviour, this study sought to examine the nature and operation of social norms relating to chemsex among gay men residing in South London. METHODS In-depth interviews were conducted with thirty self-identifying gay men (age range 21-53) who lived in three South London boroughs, and who had used either crystal methamphetamine, mephedrone or GHB/GBL either immediately before or during sex with another man during the previous 12 months. Data were subjected to a thematic analysis. In addition, two focus groups (n=12) were conducted with gay men from the community to explore group-level perceptions of drug use and chemsex. RESULTS Chemsex was perceived as ubiquitous amongst gay men by a majority of participants, who additionally described a variety of ways it is arranged (including mobile apps) and a variety of settings in which it occurs (including commercial and private settings). Chemsex was associated with unique sexual permissions and expectations, although participants also described having personal boundaries with respect to certain drug and sex practices, suggesting within-group stigmatisation. CONCLUSION This study clearly documents exaggerated beliefs about the ubiquity of chemsex, shifts in the perceived normativity of certain settings and means to facilitate chemsex, and attitudes revealing stigma against certain types of chemsex and men who engage in it. There is a need for health promotion interventions to challenge social norms relating to drug use generally, and chemsex specifically, and for such interventions to make use of the online settings in which chemsex is often facilitated.

Illicit drug use among gay and bisexual men in 44 cities: Findings from the European MSM Internet Survey (EMIS). THE INTERNATIONAL JOURNAL OF DRUG POLICY 2016; 38:4-12. [PMID: 27788450 DOI: 10.1016/j.drugpo.2016.09.007] [Citation(s) in RCA: 162] [Impact Index Per Article: 20.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2016] [Revised: 08/28/2016] [Accepted: 09/28/2016] [Indexed: 12/21/2022]
Abstract
BACKGROUND Anecdotal evidence suggests that men who have sex with men (MSM) are increasingly combining sex and illicit drugs (an activity referred to as 'chemsex'), in particular GHB/GBL, ketamine, crystal meth, or mephedrone (here called 4-chems). Use of such drugs has been associated with mental health and sexual health harms. We aim to compare patterns of illicit drug use among MSM in 44 European urban centres. METHODS In 2010, EMIS recruited 174,209 men from 38 countries to an anonymous online questionnaire in 25 languages. As harm reduction services for drugs and sex are organised at a local level, we chose to compare cities rather than countries. We defined 44 cities based on region/postal code and settlement size. For multivariable regression analyses, three comparison groups of MSM not living in these cities were applied: MSM living in Germany, the UK, and elsewhere in Europe. RESULTS Data from 55,446 MSM living in 44 urban centres were included. Use of 4-chems (past 4 weeks) was highest in Brighton (16.3%), Manchester (15.5%), London (13.2%), Amsterdam (11.2%), Barcelona (7.9%), Zurich (7.0%) and Berlin (5.3%). It was lowest in Sofia (0.4%). The rank order was largely consistent when controlling for age, HIV diagnosis, and number of sexual partners. City of residence was the strongest demographic predictor of chemsex-drug use. CONCLUSION Use of drugs associated with chemsex among MSM varies substantially across European cities. As city is the strongest predictor of chemsex-drug use, effective harm reduction programmes must include structural as well as individual interventions.
