Drug use and sexual risk among gay and bisexual men who frequent party venues

The "Chemsex" Phenomenon and Its Relationship with Psychological Variables in Men Who Have Sex with Men

Chemsex is described as the use of psychoactive substances during sexual activity to sustain, enhance, disinhibit, or facilitate the sexual experience. It preferentially concerns men who have sex with men. The main objective of this study was to examine the relationship between participation in chemsex and the psychological variables impulsivity, sexual assertiveness, and hypersexuality. The sample was composed of 137 Spanish men. A total of 104 participants reported that they had engaged in chemsex, with ages ranging from 19 to 42 years (M = 31.41, SD = 4.83). A total of 33 participants reported that they had never participated in chemsex sessions. The participants were contacted and recruited at social centers, LGBT associations, and key informants. Results showed that men who participated in chemsex reported higher impulsivity, higher hypersexuality, and lower sexual assertiveness than those who have never participated in it. The frequency of participation in chemsex, as well as the number of substances consumed, was positively and significantly correlated with dimensions of impulsivity and hypersexuality. This frequency and this consumption were negatively and significantly correlated with sexual assertiveness. Findings showed significant differences in the psychological variables based on the number of consumed substances (polydrug use/consumption of one substance) and the time of consumption (before, during or before and during sex). In conclusion, the study demonstrates the existence of a clear relationship between the experience of chemsex and psychological factors such as being an impulsive person, presenting hypersexual behavior, and/or having low sexual assertiveness.

Prevalence of methamphetamine use among gay, bisexual and other men who have sex with men: A systematic review and meta-analysis

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.

Substance Use and Risky Sexual Behavior in the PrEP Outpatient Clinic at the University Hospital of Brasília

(1) Background: To evaluate the epidemiological profile of people who use drugs at the PrEP outpatient clinic of the University Hospital of Brasília; (2) Methods: Cross-sectional study with a review of data from medical records referring to the first medical consultation. The prevalence ratio was calculated using a Poisson regression model with robust variance; (3) Results: A total of 53% of subjects reported drug use in the last 3 months. The unadjusted prevalence ratio of drug use in trans women was PR: 9.0 (95%CI: 1.4-57.5). people who use drugs have a 1.9 times higher prevalence of STI diagnosis, and a 2.4 times higher prevalence of partners compared to non-users; (4) Conclusions: Substance use was associated with a higher STI prevalence ratio and number of sexual partners.

"It's not just the hit itself": the social practice of injecting drug use among gay and bisexual men in Australia

BACKGROUND

Injecting drug use is purportedly more common among gay and bisexual men (GBM) than the general Australian population. Approaches designed to support the wellbeing of people who inject drugs may not be effective for GBM who inject, due to divergent settings, substances, and/or symbolism. We sought to identify the critical elements shaping injecting among GBM as a social practice and the implications for health and psychosocial wellbeing.

METHODS

We conducted 19 in-depth interviews with GBM in Australia with lifetime experience of injecting drug use, adopting the Frameworks Method for data analysis. Framed by social practice theory, transcripts were coded to delineate the constituent material, competency, and meaning elements of GBM's injecting practices. We developed themes encompassing the dynamic interrelationship between practice elements and wellbeing aspects.

RESULTS

Of 19 participants interviewed (aged 24-60 years), 17 identified as gay, two as bisexual. Injecting histories ranged from 2-32 years; most injected methamphetamine (n = 18). Injecting involved the integration of sexual function with substances and injecting skills in dyadic/communal settings. Beyond traditional harm reduction aspects, 'safe injecting' concerned trustworthiness of fellow practitioners, preventing addiction, and maintaining a solid self-concept. Injecting occurred as a dyadic/communal practice, in which an uneven distribution of materials (substances, sexual capital) and competencies (self-injecting) influenced risk and power dynamics. Pleasurable meanings of belonging, desirability and self-actualisation - gained from communities of practice - conflicted with injecting-related stigma, social dependencies, and fear of harms to body, mind, and sense of self.

CONCLUSION

Injecting is a heterogenous practice, including among GBM. Shifting configurations of its composite elements influence GBM's perceptions and experiences of pleasure, risk, and harms. Efforts to support their wellbeing should take a dyadic/communal approach and seek to rectify the uneven distribution of material and competency elements in these settings.

Marijuana and illicit drugs: Correlates of condomless anal sex among adolescent and emerging adult sexual minority men

The association between "illicit drugs" (e.g., cocaine/crack, methamphetamine, gamma-hydroxybutyrate-GHB, ketamine, and ecstasy) and condomless anal sex (CAS) with casual partners is well established for sexual minority men (SMM). Recent evidence from adult SMM has indicated that marijuana is associated with the occurrence of CAS with casual partners above and beyond illicit drug use. The purpose of the current study was to evaluate associations between CAS and the use of marijuana and illicit drugs in a sample of young SMM (aged 15-24). Participants (n = 578) completed an online survey assessing demographics, current PrEP prescription, age, marijuana use, as well as drug use and sexual behavior in the past 90 days. A hurdle model simultaneously predicted the occurrence of CAS as well as the frequency of CAS among those reporting it. Illicit drug use was associated with both the occurrence (OR = 2.26; p = .01) and frequency of CAS (RR = 1.63; p = .02). In contrast, marijuana use was associated with the occurrence (OR = 1.69; p = .01), but not the frequency of CAS (RR = 1.07; p = .74). Findings mirror recent observations in large samples of adult SMM. While the effect size of marijuana is more modest than illicit drug use, marijuana does have significant and unique associations with the occurrence of CAS. HIV prevention services for young SMM may therefore benefit from assessing and addressing marijuana use in the context of HIV sexual behavior.

Variations in Sexual Behaviors by Use of Specific Substances Among Vancouver Gay, Bisexual, and Other Men Who Have Sex with Men: An Event-Level Analysis

Event-level studies measure substance use and sexual behaviors happening during a specific sexual encounter, ensuring that both variables are temporally paired. This study explored the event-level associations between a range of sexual behaviors (masturbation, anal sex, oral sex, rimming, fisting, sex toys, and group sex) and five sexualized substances (poppers, methamphetamine, GHB, ecstasy/MDMA, and ketamine) used during 11,582 sexual events reported by 762 gay, bisexual, and other men who have sex with men (GBMSM) in Vancouver, Canada. Data were obtained from a prospective cohort of GBMSM who self-reported their behaviors via computer-based questionnaires on their last sexual encounter with up to five of their most recent partners in the past six months. These clustered data were analyzed with multivariable generalized linear mixed models. Participants reported popper use in 16.1% of sexual encounters, methamphetamine in 8.6%, gamma-hydroxybutyrate (GHB) in 4.1%, ecstasy/3,4-methylenedioxymethamphetamine (MDMA) in 3.3%, and ketamine in 1.5%. Condomless receptive anal sex (25.0% of events) was associated with increased odds of using poppers, methamphetamine, GHB, and ecstasy/MDMA. Group sex (13.1% of events) and sharing sex toys (2.0% of events) were more likely with the use of all five substances. Receiving money/drugs/goods in exchange for sex (2.5% of events) was associated with increased odds of poppers, methamphetamine, GHB, and ecstasy/MDMA use. GBMSM living with HIV (29.9% of participants) had higher odds of using poppers, methamphetamine, and GHB, but lower odds of using ecstasy/MDMA. In conclusion, these event-level results suggest public health strategies are needed to address the possible negative impacts of sexualized substance use among GBMSM.

We Have a Lot to Do: Lack of Sexual Protection and Information-Results of the German-Language Online Survey "Let's Talk About Chemsex"

Background: The prevalence of chemsex and sexualized substance use is increasing in several European countries, particularly among men who have sex with men. In this subgroup, illegal substance use is associated with increased sexual risk behavior, which can result in severe physical and psychological impairments. The present study examined the incidence and prevalence of chemsex in German-speaking countries. Methods: To further describe the high-risk group of Chemsex users, participants (N = 429) were asked about their psychotropic substance use, sexual and health-related behavior, health status, and socio-demographic information by using an online questionnaire. Whether Chemsex has negative effects on well-being was measured with the WHO well-being index. Of additional interest was how informed Chemsex users are about the topic and what needs are placed on the practitioners. The online questionnaire consisted of 105 items, and data was collected from March to May 2019. Thousand forty seven datasets were saved with a dropout rate of 59%, 123 completed questionnaires fulfilled the criteria for chemsex users (n =123). Results: There were no significant differences in well-being between chemsex users and non-users. All participants protected themselves against sexually transmitted diseases irregularly or not at all. The majority of chemsex users reported intermittently using illegal substances (ketamine, methamphetamine, mephedrone, γ-butyrolactone/γ-hydroxy butyric acid). They viewed their sexual and substance use behavior as problematic, but few showed motivation for behavior change. Chemsex users clearly expressed a need for more information and advice centers. Conclusion: The results provide information on chemsex users that can be used for the future development of a therapy manual and thus contribute to improving health care for this group. The prevalence of chemsex is increasing and urgently needs more research to protect clients from health impairments and stigmatization.

Testing the drug use and condomless anal sex link among sexual minority men: The predictive utility of marijuana and interactions with relationship status

BACKGROUND

The association between drug use and condomless anal sex (CAS) is well documented among sexual minority men (SMM). Less is known about whether this association generalizes to marijuana and across relationship status and sexual agreements groups (single, partnered monogamous, partnered open -outside partners permitted, and partnered monogamish -outside partners permitted when main partners are together).

METHODS

A nationwide sample of SMM (N = 65,707) were recruited through a geosocial networking app between November 2017 and November 2019. Participants reported on drug use and instances of CAS with casual partners in the previous 30 days.

RESULTS

Both marijuana and club drug use were associated with the occurrence of CAS with casual partners among single men. Only club drug use was associated with CAS frequency in this group. The association between marijuana and the occurrence of CAS did not differ significantly among monogamous men, while the associations between club drug use and the occurrence as well as frequency of CAS were significantly weaker. Meanwhile, the associations between club drug use and the occurrence as well as frequency of CAS did not differ significantly between single and non-monogamous (open and monogamish) subgroups; however, the association between marijuana and the occurrence of CAS was significantly weaker.

CONCLUSIONS

Findings largely replicated the robust association between club drug use and CAS with casual partners. They support the assertion that marijuana use predicts sexual risk for some SMM subgroups. Finally, they illustrate the potential for relationship status - and sexual agreements - to contextualize associations between drug use and CAS.

Trends in gamma-hydroxybutyrate-related harms based on ambulance attendances from 2012 to 2018 in Victoria, Australia

BACKGROUND AND AIMS

Although the prevalence of gamma-hydroxybutyrate (GHB) use is relatively low globally, harms related to the drug appear to be increasing. Few existing studies present reliable, representative, population-level data on GHB-related harms. The aim of this study was to investigate trends in acute GHB-related harms within an ambulance database in Australia.

DESIGN, SETTING AND PARTICIPANTS

Cross-sectional, retrospective analysis of data on all GHB-related ambulance attendances in the state of Victoria, Australia during a 7-year period (January 2012-December 2018) MEASUREMENTS: Presentations were characterized based on patient demographics, transport to hospital, co-occurring substance use (i.e. GHB only, alcohol, methamphetamine, heroin, benzodiazepine and cannabis) and clinical presentation (e.g. symptoms of anxiety, psychosis, depression).

FINDINGS

There were 5866 GHB-related ambulance attendances between 2012 and 2018, with the prevalence rate increasing from 8.8 per 100 000 population in 2012 to a maximum of 21.7 per 100 000 population in 2017. Methamphetamine [odds ratio (OR) = 6.23, P < 0.001] and benzodiazepine-related (OR = 1.43, P < 0.001) co-occurrences; ages between 18-29 (OR = 6.58, P < 0.001) and 30-39 years (OR = 2.02, P < 0.001); and male gender (OR = 1.23, P < 0.001) were significant predictors of GHB-related attendances.

CONCLUSIONS

There has been a 147% increase in the prevalence of GHB-related ambulance attendances in Victoria, Australia between 2012 and 2019, largely attributable to a growth in the proportions of people using gamma-hydroxybutyrate alone or concurrently with methamphetamine.

Growing Up, Hooking Up, and Drinking: A Review of Uncommitted Sexual Behavior and Its Association With Alcohol Use and Related Consequences Among Adolescents and Young Adults in the United States

Hookups are uncommitted sexual encounters that range from kissing to intercourse and occur between individuals in whom there is no current dating relationship and no expressed or acknowledged expectations of a relationship following the hookup. Research over the last decade has begun to focus on hooking up among adolescents and young adults with significant research demonstrating how alcohol is often involved in hooking up. Given alcohol’s involvement with hooking up behavior, the array of health consequences associated with this relationship, as well as its increasing prevalence from adolescence to young adulthood, it is important to determine the predictors and consequences associated with alcohol-related hooking up. The current review extends prior reviews by adding more recent research, including both qualitative and experimental studies (i.e., expanding to review more diverse methods), research that focuses on the use of technology in alcohol-related hookups (i.e., emerging issues), further develops prevention and intervention potentials and directions, and also offers a broader discussion of hooking up outside of college student populations (i.e., expanding generalization). This article will review the operationalization and ambiguity of the phrase hooking up, the relationship between hooking up and alcohol use at both the global and event levels, predictors of alcohol-related hooking up, and both positive and negative consequences, including sexual victimization, associated with alcohol-related hookups. Throughout, commentary is provided on the methodological issues present in the field, as well as limitations of the existing research. Future directions for research that could significantly advance our understanding of hookups and alcohol use are provided.

Recent epidemiology of sexually transmissible enteric infections in men who have sex with men

PURPOSE OF REVIEW

Sexual transmission of enteric pathogens in men who have sex with men (MSM) has been described since the 1970s. Recently, an increasing number of enteric infection outbreaks have been reported in MSM. This article summarizes recent outbreaks and discusses the key issues for prevention and control.

RECENT FINDINGS

Sexually transmissible enteric infections (STEIs) can spread rapidly and internationally within highly connected MSM populations and are often associated with antimicrobial resistance (AMR). The infections often cluster in high-risk groups of HIV-positive MSM who are more likely to engage in diverse sexual practices and chemsex, and to have multiple other sexually transmitted infections (STIs).

SUMMARY

The roles of asymptomatic and/or persistent infection and other contextual factors in STEI transmission are not well described. STEI-associated AMR is increasing and has potential to spread rapidly in MSM, warranting further public health attention. A better understanding of the factors associated with sexual transmission will enable the development of more effective control measures. A holistic approach that promotes health and wellbeing as well as infection prevention and management is needed.

"You can smell the freedom": a qualitative study on perceptions and experiences of sex among Swedish men who have sex with men in Berlin

PURPOSE

The purpose of this study was to explore the perceptions and experiences of sex among Swedish Men who have Sex with Men (MSM) in Berlin.

BACKGROUND

MSM are disproportionally affected by HIV.Berlin is also a key destination when looking into where Swedish MSM sero-convert, while travelling.

METHOD

A qualitative study with semi-structured interviews using open-ended questions with participants recruited through network sampling. Data were analysed with content analysis.

PARTICIPANTS

15 Swedish cis-men (as in non-transgender) who have sex with men aged 25-44 years, who travelled to or were living in Berlin. To be included in the study, the participants had to be cis-MSM, Swedish citizens, spending time in Berlin and having sex in both settings.

RESULTS

For a majority of the participants, sex was the main reason for going to Berlin but cultural aspects like art and the techno scene were also important. Berlin was perceived as a sex-oriented city providing venues where respondents did not have to care about reputation and status and where social and sexual spaces co-existed side by side. This in sharp contrast to Sweden, which represented a limiting environment both in culture and what was available culturally and sexually.

CONCLUSION

The men interviewed experienced multiple partners and had a broad sexual repertoire both abroad and at home. However, the behaviour was amplified in Berlin. The men did not alter their safer sex practice depending on if they had sex in Sweden or Berlin. The high mobility and vulnerability for HIV/sexually transmitted infection (STI) among these men highlights the need of increased access to antiretroviral treatment, pre-exposure prophylaxis for HIV and low-threshold HIV/STI testing services in Europe.

Stress and substance use among sexual and gender minority individuals across the lifespan

Sexual and gender minority (SGM) individuals face marked disparities in substance use. The present narrative review explores research on substance use in SGM communities using a minority stress theory lens. We define the SGM population and minority stress, and explore stresses and substance use disparities in adolescence, adulthood, and older age. Though research on this topic is beginning to highlight the relationship between stress and substance use for SGM individuals, more work is needed on older SGM populations and in translating research findings to effective interventions.

Gay Circuit Parties in Barcelona and Their Impact on Gonorrhea Incidence

This study explored the role of circuit parties on the incidence of gonorrhea among men who have sex with men (MSM) in Barcelona (Spain). Specifically, it aimed to detect cyclic peaks in the number of reported diagnoses of gonorrhea after gay circuit parties. We analyzed monthly cases of gonorrhea reported from January 2007 through December 2016 after the main annual gay circuit parties in Barcelona. We used the integer autoregressive model for time series with discrete values. The performance of the model was tested in heterosexual men and women, in whom the circuit parties could be expected to have no impact. A sensitivity analysis was conducted, changing post-event diagnosis windows to 1 week later/1 week before. In the study period, a total of 4182 of gonorrhea cases were detected, of which 74.8% (n = 2181) occurred in men who identified themselves as MSM. The average annual increase in gonorrhea cases reported among MSM was 32.57%. In an independent analysis of each gay circuit party, cases increased significantly in two of them. The results were also similar for same-sex practices among men only. On controlling for the increasing trend over the study period and the seasonal effect, an average of 1.16 gonorrhea cases in MSM (95% CI: 0.68, 1.64) were attributable to the celebration of one of the gay circuit parties considered. During the expected outbreak, an average of 13 gonorrhea cases were detected and between 5 and 13% were attributable to one of the circuit parties. In view of these findings, participants should consider seeking advice from their healthcare provider and practice safer sex using condoms to prevent sexually transmitted infections. Local public health services should be reinforced to ensure care for participants during and after gay circuit parties. More research is needed to design and implement preventive programs.

Chemsex and new HIV diagnosis in gay, bisexual and other men who have sex with men attending sexual health clinics

OBJECTIVES

The aim of the study was to analyse associations between chemsex and new HIV and sexually transmitted infection (STI) diagnoses among gay, bisexual and other men who have sex with men (GBMSM) accessing sexual health clinics.

METHODS

A retrospective case note review was carried out for all GBMSM attending two London sexual health clinics between 1 June 2014 and 31 July 2015.

RESULTS

Chemsex status was documented for 1734 of 1840 patients. Overall, 27.1% (n = 463) disclosed current recreational drug use, of whom 286 (16.5%) disclosed chemsex participation and 74 of 409 (18.1%) injected drugs. GBMSM who were already HIV positive were more likely to disclose chemsex participation [adjusted odds ratio (AOR) 2.55; 95% confidence interval (CI) 1.89-3.44; P < 0.001]. Those disclosing chemsex participation had higher odds of being newly diagnosed with HIV infection (AOR 5.06; 95% CI 2.56-10.02; P < 0.001), acute bacterial STIs (AOR 3.94; 95% CI 3.00-5.17; P < 0.001), rectal STIs (AOR 4.45; 95% CI 3.37-6.06; P < 0.001) and hepatitis C (AOR 9.16; 95% CI 2.31-36.27; P = 0.002). HIV-negative chemsex participants were also more likely to have accessed post-exposure prophylaxis for HIV in the study period and to report sex with a discordant HIV- or hepatitis C virus-infected partner (P < 0.001).

CONCLUSIONS

Chemsex disclosure in sexual health settings is associated with higher rates of STI diagnoses, including HIV infection and hepatitis C. GBMSM attending sexual health services should therefore be assessed for chemsex participation and disclosure should prompt health promotion, harm minimization and wellbeing interventions.

When "Chems" Meet Sex: A Rising Phenomenon Called "ChemSex"

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.

Pharmacological Treatment in γ-Hydroxybutyrate (GHB) and γ-Butyrolactone (GBL) Dependence: Detoxification and Relapse Prevention

The misuse of γ-hydroxybutyrate (GHB) for recreational purposes has resulted in an increase in GHB-related problems such as intoxications, dependence and withdrawal in several countries in Europe, Australia and the US over the last decade. However, prevalence rates of misuse of GHB and its precursor, γ-butyrolactone (GBL), are still relatively low. In this qualitative review paper, after a short introduction on the pharmacology of GHB/GBL, followed by a summary of the epidemiology of GHB abuse, an overview of GHB dependence syndrome and GHB/GBL withdrawal syndrome is provided. Finally, the existing literature on management of GHB detoxification, both planned and unplanned, as well as the available management of GHB withdrawal syndrome, is summarized. Although no systematic studies on detoxification and management of withdrawal have been performed to date, general recommendations are given on pharmacological treatment and preferred treatment setting.

Substance use and STI acquisition: Secondary analysis from the AWARE study

OBJECTIVES

Sexually transmitted infections (STIs) are significant public health and financial burdens in the United States. This manuscript examines the relationship between substance use and prevalent and incident STIs in HIV-negative adult patients at STI clinics.

METHODS

A secondary analysis of Project AWARE was performed based on 5012 patients from 9 STI clinics. STIs were assessed by laboratory assay and substance use by self-report. Patterns of substance use were assessed using latent class analysis. The relationship of latent class to STI rates was investigated using Poisson regression by population groups at high risk for STIs defined by participant's and partner's gender.

RESULTS

Drug use patterns differed by risk group and substance use was related to STI rates with the relationships varying by risk behavior group. Substance use treatment participation was associated with increased STI rates.

CONCLUSIONS

Substance use focused interventions may be useful in STI clinics to reduce morbidity associated with substance use. Conversely, gender-specific sexual health interventions may be useful in substance use treatment.

Social norms related to combining drugs and sex ("chemsex") among gay men in South London

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.

Chemsex and the city: sexualised substance use in gay bisexual and other men who have sex with men attending sexual health clinics

The objective of this study was to analyse associations between sexualised substance use (chemsex), STI diagnoses and sexual behaviour among gay bisexual and other men who have sex with men accessing sexual health clinics to better inform clinical pathways. A retrospective case notes review was undertaken following the introduction of more detailed and holistic profomas for all gay bisexual and other men who have sex with men attending two London sexual health clinics between 1 June 2014 and 31 January 2015. Chemsex status was documented for 655/818. Overall, 30% disclosed recreational drug use of whom 113 (57%) disclosed chemsex and 27 (13.5%) injecting drugs. HIV-positive gay bisexual and other men who have sex with men were more likely to disclose chemsex (AOR 6.68; 95% CI 3.91–11.42; p < 0.001). Those disclosing chemsex had a higher incidence of acute bacterial STIs (AOR 2.83 CI 1.79–4.47; p < 0.001), rectal STIs (AOR 3.10 CI 1.81–5.32; p < 0.001) or hepatitis C (AOR 15.41 CI 1.50–158.17; p = 0.021). HIV incidence in the study period was 1.8% (chemsex) vs. 0.9% (no chemsex) (p = 0.61). Chemsex was associated with having more sexual partners, transactional sex, group sex, fisting, sharing sex toys, injecting drug use, higher alcohol consumption and the use of ‘bareback’ sexual networking applications (p < 0.004). Chemsex participants were also more likely to have accessed post-exposure prophylaxis for HIV in the study period and report sex with a discordant HIV or hepatitis C-infected partner (p < 0.001). Chemsex disclosure is associated with higher risk-taking behaviours, acute bacterial STIs, rectal STIs and hepatitis C incidence. HIV incidence was higher but not significantly so in the study period. Chemsex disclosure in sexual health clinics should prompt an opportunity for prevention, health promotion and wellbeing interventions.

Pharmacologic, Pharmacokinetic, and Clinical Assessment of Illicitly Used γ-Hydroxybutyrate

γ-Hydroxybutyrate (GHB) is a common drug of abuse and poses important health risks to users in the form of respiratory, cardiovascular, mental, or traumatic adverse events. GHB has non-dose-proportional effects and pharmacologic effects such as sedation and retrograde amnesia, which can incapacitate people targeted for assault. It has Krebs cycle metabolism, rapid clearance, relative hydrophilicity, and unique drug interactions. Promptly seeking medical attention during intentional or inadvertent overdose is critical to survival, as is prompt supportive care once medical personnel are alerted. People drugged before assault also need to promptly notify authorities because the period to detect the drug in the urine or blood is brief and the ultimate metabolites are carbon dioxide and water. After acute treatment has passed, withdrawal could be severe in chronic abusers that could harm the patient directly or drive them back into reuse.

Heterogeneity in the Relationship of Substance Use to Risky Sexual Behavior Among Justice-Involved Youth: A Regression Mixture Modeling Approach

Justice-involved adolescents engage in high levels of risky sexual behavior and substance use, and understanding potential relationships among these constructs is important for effective HIV/STI prevention. A regression mixture modeling approach was used to determine whether subgroups could be identified based on the regression of two indicators of sexual risk (condom use and frequency of intercourse) on three measures of substance use (alcohol, marijuana and hard drugs). Three classes were observed among n = 596 adolescents on probation: none of the substances predicted outcomes for approximately 18 % of the sample; alcohol and marijuana use were predictive for approximately 59 % of the sample, and marijuana use and hard drug use were predictive in approximately 23 % of the sample. Demographic, individual difference, and additional sexual and substance use risk variables were examined in relation to class membership. Findings are discussed in terms of understanding profiles of risk behavior among at-risk youth.

The behavioural profile of gamma-hydroxybutyrate, gamma-butyrolactone and 1,4-butanediol in humans

Gamma-hydroxybutyrate (GHB) is a putative neurotransmitter, a drug of abuse, and a medical treatment for narcolepsy and other neuropsychiatric disorders. Its precursors gamma-butyrolactone (GBL) and 1,4-butanediol (1,4-BD) are endogenously converted to GHB and thereby exert their psychobehavioural effects. In humans, GHB has a wide spectrum of properties ranging from stimulation and euphoria in lower doses, to sedation, deep sleep, and coma after ingestion of high doses. However, behavioural studies in healthy volunteers remain scarce and are usually limited to psychomotor performance testing. Most available data arise from either qualitative studies with illicit users or clinical trials examining therapeutic properties of GHB (then usually termed sodium oxybate). Here, we present an overview of the behavioural effects of GHB, GBL, and 1,4-BD in these three populations. GHB and its precursors strongly influence behaviours related to core human autonomic functions such as control of food intake, sexual behaviour, and sleep-wake regulation. These effects are instrumentalised by illicit users and clinically utilised in neuropsychiatric disorders such as narcolepsy, fibromyalgia, and binge-eating syndrome. Considering the industry withdrawal from psychopharmacology development, repurposing of drugs according to their behavioural and clinical profiles has gained increasing relevance. As such, GHB seems to be an attractive candidate as an experimental therapeutic in depression.

Increasing use of 'party drugs' in people living with HIV on antiretrovirals: a concern for patient safety

Use of 'party drugs', a particular set of recreational drugs used in the context of 'ChemSex', is frequent among MSM living with HIV. A recently published observational study showed that more than half of HIV-infected MSM interviewed reported use of illicit substances in the previous 3 months, with frequent concomitant use of three or more drugs. These substances are a combination of 'club drugs' (methylenedioxymethamphetamine, gamma-hydroxybutyrate, ketamine, benzodiazepine) and drugs that are more specifically used in a sexualized context (methamphetamine, mephedrone, poppers and erectile dysfunction agents). Although formal data on pharmacokinetic or pharmacodynamic interactions between recreational drugs and antiretroviral agents are lacking, information regarding potentially toxic interactions can be theorized or sometimes conclusions may be drawn from case studies and cohort observational studies. However, the risk of coadministering party drugs and antiretrovirals should not be overestimated. The major risk for a drug-drug interaction is when using ritonavir-boosting or cobicistat-boosting agents, and maybe some nonnucleoside reverse transcriptase inhibitors. Knowledge of the metabolic pathways of 'party drugs' may help in advising patients on which illicit substances have a high potential for drug-drug interactions, as this is not the case for all.

Recreational drug use and risks of HIV and sexually transmitted infections among Chinese men who have sex with men: Mediation through multiple sexual partnerships

Background

Recreational drug use (RDU) may result in sexual disinhibition and higher risk for HIV and other sexually transmitted infections (STIs) among men who have sex with men (MSM) in China. We assessed whether RDU was associated with HIV, syphilis, and herpes simplex virus type 2 (HSV-2) within the context of multiple sexual partnerships and unprotected sex.

Methods

We conducted a cross-sectional study among sexually-active MSM in six Chinese cities (Kunming, Jinan, Changsha, Zhengzhou, Nanjing, and Shanghai) in 2012–2013. We interviewed participants regarding RDU and sexual activity and drew blood for HIV, syphilis, and HSV-2. We fit multiple logistic regression models to assess associations of drug use and HIV, syphilis and HSV-2 infections, controlling for number of sexual partners and unprotected sex.

Results

Of 3830 participants, 28% reported ever using ≥1 of these drugs in the past 6 months: popper (alkyl nitrites), ecstasy, ice (methamphetamine), amphetamine, tramadol, and ketamine. In the past six months, 62% of MSM reported ≥2 sexual partners and 76% did not use condoms at last sexual encounter. HIV, syphilis and HSV-2 prevalences were 9.2%, 12.2%, and 10.3%, respectively.RDU was associated with HIV infection (aOR = 1.67; 95% CI, 1.31-2.13). Men with RDU were more likely to report multiple sexual partners (OR = 1.69; 95% CI, 1.44-1.98) and unprotected sex (aOR = 1.25; 95% CI, 1.05-1.49). The RDU-HIV association persisted (aOR = 1.58; 95% CI = 1.23-2.02) after adjusting for numbers of partners.

Conclusions

RDU was associated with multiple sexual partnerships, unprotected sex, and HIV among Chinese MSM. It is plausible that RDU is a driver of increased sexual/HIV risk and/or may be an associated behavior with sexually risky lifestyles. Community engagement is needed.
