Chemsex and Psychosis: A Systematic Review

Examining the Effects of PrEP Use on Sexual Behaviors and Sexually Transmitted Infections Among Chinese Men who have Sex with Men: A Cross-Sectional Study

Men who have sex with men (MSM) is a high-risk population for HIV and sexually transmitted infections (STIs). Pre-exposure prophylaxis (PrEP) is effective in HIV prevention. This study aims to examine the differences in sexual behaviors, STI prevalence and HIV/STI testing across subgroups of MSM with various PrEP use. Data were collected via a cross-sectional survey in an MSM community in Xi'an, Shaanxi, from 2022.01 to 2022.09. Participants were categorized as 'PrEP-naïve and unwilling to use', 'PrEP-naïve but willing to use', and 'current or former PrEP users'. Shannon index was used to assess sexual act diversity and multivariate logistic regression analyzed factors associated with PrEP use. Of the 1,131 MSM participants, 23.52% were PrEP-naïve and unwilling, 64.98% were PrEP-naïve but willing, and 11.49% were current or former PrEP users. The PrEP-naïve but willing group had the highest recent STI testing rates at 73.06% and showed greater sexual act diversity (Shannon index 1.61). This group also had the highest syphilis rates (7.49% vs. 6.47% and2.54%, p < 0.01). Younger age (18-30: OR = 0.39 (0.18-0.85); 31-40: OR = 0.43 (0.20-0.96)) and lower education (high school/vocational: OR = 0.15 (0.04-0.58); associate degree: OR = 0.21 (0.06-0.71)) were factors that negatively influenced PrEP use. Current or former PrEP users had the highest oropharyngeal gonorrhea (14.39% vs. 9.68% and 5.80%, p < 0.01) and overall gonorrhea rates (20.86% vs. 17.17% and 8.37%, p < 0.001). 'PrEP-naïve but willing' participants consistently demonstrated high-risk sexual behavior, increased STI testing, and more diverse sexual acts, whereas PrEP users had the highest STI prevalence.

What Chemsex does to the brain - neural correlates (ERP) regarding decision making, impulsivity and hypersexuality

Chemsex describes the use of specific substances (methamphetamine, GHB/GBL, mephedrone, ketamine) which initiate or enhance sexual experiences and is mainly prevalent among men who have sex with men. Many Chemsex users experience somatic complications (for example sexually transmitted diseases) and sometimes adverse sociological, psychological, and neurological symptoms, such as depression, impulse control disorders or hypersexuality. Changes in impulsivity and deficits in executive functions have demonstrated to be associated with addiction and impulse control disorders as well as frontal brain dysfunction and behavioral control deficits. This study aims to explore the effects of neurophysiological correlates of inhibition and decision making in Chemsex users with an EEG paradigm using event-related potentials (N2, P3). 15 Chemsex users and 14 matched control subjects, all of them men who have sex with man, participated in an auditory Go/NoGo/Voluntary Selection EEG paradigm. In addition, clinical data (e.g. regarding depression), demographic information as well as measures of well-being and sexual behavior were collected. The results demonstrated that clinical symptoms, hypersexuality, and sexual risk behavior were more pronounced in Chemsex users compared to non-users. P3 amplitudes did not differ significantly between groups. However, the Chemsex users showed decreased electrophysiological N2 responses in fronto-central brain regions during decision-making, indicating compromised executive function and inhibitory control. The observed impairments may lead to increased risk behavior regarding drug abuse and hypersexuality. Understanding the neurobiological mechanisms can contribute to targeted interventions in order to mitigate the negative consequences of engaging in Chemsex and improve general well-being.

Sexualized drug use and chemsex: A bibliometric and content analysis of published literature

Sexualized drug use (SDU) describes drug-facilitated sexual enhancement, and chemsex is an SDU subculture involving the use of specific drugs by men who have sex with men (MSM). This study aimed to identify research trends, foci, and themes within the SDU and chemsex-specific literature. The Web of Science Core Collection was searched with a list of SDU synonyms. All SDU-related articles were analyzed using the R package, bibliometrix. Full text review identified chemsex-specific records, and text was extracted verbatim for content analysis in Leximancer. The search returned 1,866 unique records. A total of 521 addressed SDU, and 301 papers specifically addressed chemsex. The small but growing SDU literature primarily addressed consensual encounters between MSM, and drug-facilitated assault experienced by women, in Western settings. Little attention was given to transgender communities or consensual SDU in cisgender heterosexual individuals. The literature primarily viewed SDU through a public health lens, specifically focusing on the risk conferred to sexual health.The SDU and chemsex-specific literature are potentially limited in scope and may inadequately capture the geographical, demographic, and cultural diversity of these phenomena. Future research should address the myriad social and health implications of SDU and chemsex participation across all relevant communities and settings.

"I Can't Get No Satisfaction"-Psychosocial Aspects and Awareness of Negative Impacts in Chemsex Users: Results from an Anonymous Online Survey

Chemsex is the interplay of substance use by men who have sex with men (MSM) in sexual contexts. The minority stress model and the identity process theory are explanatory models. In this study, we investigated whether (i) differences in certain psychosocial aspects (i.e., shame, aspects of queer identity, and sexual self-concepts) exist between chemsex users and non-users, and (ii) which factors influence an awareness of negative impacts in chemsex users. We conducted an anonymous, cross-sectional, online survey, including sociodemography, sexual history, history of substance use, validated scales for shame-proneness, aspects of queer identity, and sexual self-concepts. Our analysis comprised descriptive statistics, t-tests, Spearman's correlations, and a multiple linear regression model. We recorded a total of 3257 datasets with 107 chemsex users. Chemsex users showed higher rates for risky sexual behavior. Values for shame proneness, more negative aspects of queer identity, and sexual self-concepts were elevated in chemsex users with an awareness of negative impacts. Sexual anxiety, intravenous substance use, and having had a difficult process coming out were significant predictors of feeling negative impacts. Aspects of shame, queer identity aspects, and sexual self-concepts play an important role in the field of chemsex. Different explanatory models seem to be relevant for different subgroups of chemsex users. Chemsex users with an awareness of a problem were particularly vulnerable and distressed but had the highest motivation for change. Prevention, counseling, and care might profit from the inclusion of these aspects. Further anti-stigma campaigns and a specialization of the healthcare system are needed.

Is ethyl chloride the new nitrous oxide? A case report

BACKGROUND

Over the last decade, there has been an emerging trend of recreational misuse of several drugs and inhaled solvent including ethyl chloride. This case report follows CARE guidelines and highlights, with supporting video, the neurological features of ethyl chloride intoxication.

CASE PRESENTATION

A 48-year-old man was seen for the sudden occurrence of an unsteady gait with dizziness. His only medical history was a chronic and treated HIV infection without any complications. Clinical examination revealed a cerebellar syndrome associated with impairment of short-term memory. Biological and radiological workups were normal. After several days, the patient recalled ethyl chloride inhalation. He fully recovered after being discharged from hospital.

CONCLUSION

Clinicians should recognise the clinical features and neurological manifestations of ethyl chloride intoxication due to the potential fatal cardiovascular complications of this intoxication.

Descriptive study on substance uses and risk of sexually transmitted infections in the practice of Chemsex in Spain

Background

In recent years, there has been an increasing use of sex-related substances (known as "Chemsex") to facilitate, intensify, and prolong the sexual experience of men who have sex with men. This phenomenon poses a public health problem, increasing the risk of sexually transmitted infections (STIs) and mental disorders.

Objective

The primary aim of this study was to delve into the correlation between substance use and sexual health, specifically examining the association between different substances used and the risk of sexually transmitted infections (STIs) in the context of Chemsex in Spain.

Methods

An observational, descriptive, cross-sectional study was conducted among 563 Spanish participants between January and April 2023. Non-probabilistic purposive sampling was used by the investigators. The researchers administered a questionnaire to men who have sex with men who use substances, especially in the sexual sphere, in all the autonomous communities of Spain.

Results

14.7% reported having practiced slamsex in the last year, and 17.94% were diagnosed with a Sexually Transmitted Infection in the previous 6 months. Of these, 21% were on PREP treatment, with the main STIs being gonorrhea (p < 0.001), chlamydia (p < 0.001), genital herpes (p = 0.020), and syphilis (p < 0.001). The 63.7% used methamphetamines as the main drug in the practice of chemsex.

Discussion

Chemsex in Spain is linked to a high prevalence of STIs, especially gonorrhea and chlamydia, even among those on PrEP treatment. The use of various drugs during chemsex, such as amyl nitrite, GHB, ecstasy, and others, correlates with higher rates of STIs, highlighting the need for interventions to reduce risk and harm. The drugs most associated with slamsex include ketamine, mephedrone, and methamphetamine, underscoring the importance of addressing the risk behaviors associated with this activity.

Conclusion

This study shows that chemsex appears to be associated with a high prevalence among men who have sex with men. Who use multiple substances in a sexual context, and are particularly exposed to sexually transmitted infections (STIs), indicating a particular need for STI prevention and care in this group.

Exploring practices to enhance benefits and reduce risks of chemsex among gay, bisexual, and other men who have sex with men: A meta-ethnography

BACKGROUND

Chemsex is the intentional combining of specific drugs with sex, primarily by gay, bisexual, and other men who have sex with men (GBMSM), to enhance intimacy, pleasure, and prolong sexual sessions. Practices vary across geographic and social settings. Participants report benefits and risks of chemsex. Studies have previously reviewed chemsex practices and harm reduction interventions separately. This review aims to examine both together by describing and understanding practices that men employ to navigate the perceived benefits and risks of chemsex.

METHODS

We conducted a systematic meta-ethnographic review of published qualitative literature, screening titles, abstracts, and full texts on defined inclusion and exclusion criteria. Using reciprocal and refutational translation techniques, we analysed study participants' (first-order) and researchers' (second-order) accounts of benefit-enhancing and risk-reducing chemsex practices. Finally, we employed line-of-argument synthesis techniques to develop our own higher-level interpretations (third-order constructs) of these chemsex practices.

RESULTS

Our search yielded 6356 records, from which, we included 23 articles in our review. Most studies were conducted in high-income Western countries. Across studies, participants acted at the individual, interpersonal, and community levels to enhance benefits and reduce risks, which made up our third-order constructs. Eight themes emerged from first- and second-order constructs to describe these practices, which included personal preparation, personal boundaries, biomedical measures, structured use of drugs, leaning on partners, injecting practices, group organising, watching out for others, and teaching and learning. Contextual factors like trust, agency, access, stigma, and setting moderated whether and how participants engaged in these practices, and if practices enhanced benefits or reduced risks.

CONCLUSION

Health promotion programmes and research focused on chemsex must account for the benefits and the risks that GBMSM associate with this type of sexualised drug use and target the moderating factors that shape the practices they employ to navigate these benefits and risks.

Psychological characteristics associated with chemsex among men who have sex with men: Internalized homophobia, conscientiousness and serostatus as predictive factors

Background

Although significant progress has been made in the rights of the LGBTQ+ community, even today this population still faces stigma and discrimination that impacts their mental health. In the case of men who have sex with men, it has been demonstrated that the use of drugs in a sexual context (chemsex) is one of the coping mechanisms and means of escape to deal with these situations.

Method

We assessed 284 native Spanish speakers' participants, 45,4 % were not engaged in sexualised drug use (n = 129) while 54,6 % were chemsex users (n = 155) using 18,7 % of them the injected via. The participants completed six questionnaires about life and sexual satisfaction, depression, anxiety, internalised homophobia and personality. Bivariate and multivariable logistic regression were performed to assess the associations between sexual behaviour-related and psychological variables. Kruskal-Wallis H test was used to analysed the impact on mental health of the administration via.

Results

Aged, unprotected sexual relationships, positive serostatus, homonegativity and conscientiousness predicted the chemsex engagement. Furthermore, we found differences regarding the administration via.

Conclusions

We conclude that mental health significantly correlates with the practice of chemsex, highlighting the importance of integrating mental health considerations into the prevention of risky sexual behaviors.

Sexualized substance use among gbMSM: Their perspectives on their intervention needs and counsellor competencies

INTRODUCTION

Treatments for problematic substance use by gay, bisexual and other men who have sex with men (gbMSM) in sexualized contexts must be adapted to take sociocultural aspects of these sexual practices into account. When treatment programs factor in sexuality, they most commonly address it from a biological perspective (STTBIs, HIV). This article sets out to identify intervention needs related to sexualized substance use (SSU) from the perspective of gbMSM, taking into consideration different dimensions of sexuality to offer more effective support.

METHODS

Twenty adult gbMSM, each of whom had previously participated in addiction-related treatment programs, took part in this study. We recruited through medical clinics, community organizations, social media advertising and word of mouth. Through one-on-one semi-structured interviews, participants shared their perspectives on the treatment they had received, how their sexuality had been addressed during treatment, and their perceptions of their treatment-related needs and requirements. The study analyzed and interpreted the data gathered during these interviews using a conceptual framework of sexual health combined with The Competencies, a model for addiction counselling training.

RESULTS

When the study asked participants what they would consider beneficial in terms of SSU-related treatment, they identified certain key competencies. These can be broken down into three categories - knowledge, skills and attitudes - that, together, participants perceived as critical to the development of adequate programs and services. While participants reported addiction-related knowledge was important, so too was an understanding of sexuality (e.g., sexual practices, gbMSM communities, sociocultural norms). With regard to attitudes, the study identified respect, non-judgment, acceptance and empathy as themes for most participants. Lastly, the desired skills were those permitting counsellors and other treatment providers to better align programs and services with each individual's singular reality within the context of their substance use.

CONCLUSIONS

The results of this study suggest that, to provide treatment programs adapted to the needs of gbMSM in a context of SSU, knowledge must be consolidated and new skills developed. Furthermore, both knowledge and skills need to be placed within an overarching perspective of cultural humility. Overall, improving these various competencies should improve the continuum of care in addiction treatment.

Getting Inside the Mind of Gay and Bisexual Men Who Have Sex with Men with Sexualized Drug Use - A Systematic Review

Objectives

Sexualized Drug Use (SDU) consists of using any drug purposely before or during sex with the intent of modifying sex experiences. SDU is especially practiced among Gay and Bisexual Men who have Sex with Men (GBMSM). This study aims to review the relevant literature to identify and summarize the reasons reported by GBMSM to engage in SDU.

Methods

A systematic review of the literature using PubMed/Medline, Scopus, Google Scholar, and PsycINFO, comprising qualitative and quantitative papers published between 2010 and 2022, was conducted with a narrative synthesis of the findings. PRISMA guidelines were followed.

Results

Our search identified 1400 publications, of which 23 were included. Reasons to engage in SDU were aggregated as follows: (1) Enhancing sexual sensations and performance, (2) Achieving hedonic mental and emotional states, (3) Tackling negative thoughts and feelings, and (4) Social motivations. Different sample methods and ways of asking for motivations may limit the internal validity of these conclusions.

Conclusion

Both individual and social factors are involved in the decision to engage in SDU. SDU practices should not be medicalized, however therapeutic support if needed should provide multidisciplinary, pleasure-centered, harm-reducing care interventions, specifically designed for these minorities of GBMSM.

Application of the Delphi Method for Content Validity Analysis of a Questionnaire to Determine the Risk Factors of the Chemsex

Chemsex is understood as "the intentional use of stimulant drugs to have sex for an extended time among gay, bisexual, and other men who have sex with men". It is a public health problem because of the increased incidence of cases and because of the consequences on the physical and mental health of those who practice it.

AIM

This study aimed to analyze, with the help of the Delphi method, the content validity of a new instrument to assess the risk of behaviors associated with the chemsex phenomenon.

METHOD

First, a bank of items identified from the literature was elaborated. Secondly, 50 experts with knowledge of the chemsex phenomenon at the national level were contacted. A Delphi group was formed with them to carry out two rounds of item evaluation. The linguistic evaluation (comprehension and appropriateness) was assessed using a Likert scale from 1 to 5 for each item. Items that did not reach a mean score of 4 were eliminated. Content assessment was calculated using each item's content validity index (CVI) and Aiken's V (VdA). A minimum CVI and VdA value of 0.6 was established to include the items in the questionnaire.

RESULTS

A total of 114 items were identified in the literature. In the first round of Delphi evaluation, 36 experts evaluated the items. A total of 58 items were eliminated for obtaining a CVI or VdA of less than 0.6, leaving 56 items. In a second Delphi round, 30 experts re-evaluated the 56 selected items, where 4 items were eliminated for being similar, and 10 items were also eliminated for not being relevant to the topic even though they had values higher than 0.6, leaving the scale finally composed of 52 items.

CONCLUSION

A questionnaire has been designed to assess the risk of behaviors associated with the chemsex phenomenon. The items that make up the questionnaire have shown adequate content and linguistic validity. The Delphi method proved to be a helpful technique for the proposed objective.

Prevalence, characteristics, and associated risk factors of drug consumption and chemsex use among individuals attending an STI clinic (EpITs STUDY)

Sex-related drug consumption and its health-related consequences have gained relevance in the assessment of patients with sexually transmitted infections (STIs), which pose a significant challenge to public health. We aim to assess the prevalence and characteristics of drug consumption and chemsex practices, describe the associated risk factors among general individuals attending an STI clinic, and evaluate the psychological impact associated with these behaviors. We conducted an online anonymous survey offered to patients with a diagnosis of STI in a tertiary hospital in Spain. Data included sociodemographic characteristics, sexual preferences and behavior, and assessment of drug use, chemsex, and psychological and mental health symptoms. Data from 145 subjects was collected, with a higher proportion of cis-gender men (71%), and a median age of 32 years. 64 participants (44%) reported drug use in the last year, with an observed 33.8% prevalence of chemsex consumption. Drug use and chemsex were more frequent among cis-gender men, Men who have Sex with Men (MSM), people living with HIV (PLHIV), and those reporting previous group sex. Poppers and cannabis were the most frequently reported drugs, with a prevalence close to 20% for cocaine, mephedrone, extasis, and GHB. Consequences related to drug use included unpleasant physical sensations, sexual dysfunction, and impaired sexual experience after reduction or drug discontinuation. The prevalence of drug use and chemsex practices are high among patients evaluated for STIs, especially between men, MSM, and subjects practicing group sex. The study highlights the urgent need for targeted interventions on prevention and reduction of their impact on health and social well-being.

Coronavirus (COVID-19) and sexualised drug use among men who have sex with men: a systematic review

Drug-related harms, including harms from sexualised drug use (SDU), are disproportionately experienced by sexual and gender minority people, relative to their majority counterparts. Chemsex, a type of SDU practiced mainly by MSM, is associated with methamphetamine use and increased HIV seropositivity or risk of acquisition. Therefore, participants are at increased risk of immunocompromise. Existing evidence suggests that drug use increases following natural disasters. The impact of coronavirus disease 2019 (COVID-19) on chemsex is unknown. A PRISMA-adherent systematic review was conducted to synthesise reports of changes in the prevalence, frequency, or characteristics of drug use (and factors associated with these changes) following the onset of the COVID-19 pandemic. This report presents findings related to SDU/chemsex among MSM. A comprehensive search across nine databases, supplemented with backward-forward citation searching and contact with key opinion leaders, was conducted. Two reviewers carried out title-abstract screening, full-text screening, and data extraction. Following a final, single database search, nine studies were included in the narrative synthesis. More than half the sample were studies investigating HIV pre-exposure prophylaxis use. Twenty percent of participants in most studies reported chemsex participation. In four, participants reported a net increase or maintenance of chemsex participation during the pandemic and five reported a net decrease. Increased chemsex participation was associated with loneliness, cravings, and working during the pandemic. Decreased chemsex practice was associated with COVID-19-related fear. This synthesis suggests that chemsex practice continued, and for some MSM increased, throughout COVID-19 pandemic 'lockdowns'. This may have increased COVID-19 transmission and severity among potentially vulnerable MSM.

Lethal Lust: Suicidal Behavior and Chemsex-A Narrative Review of the Literature

Chemsex is described as the use of certain drugs-commonly methamphetamine, gamma-butyrolactone (GBL)/gammahydroxybutyrate (GHB), and mephedrone-before or during planned sexual activity primarily among men who have sex with men (MSM). Evidence shows that MSM who engage in chemsex are at increased risk of physical harm, such as sexually transmittable infections (STIs), and are more likely to experience mental health symptoms. To further assess this, we reviewed the recent literature to evaluate whether the psychological impact of chemsex behavior includes suicidal ideation and suicidal attempts. Pubmed/MEDLINE was searched for articles reporting suicidal ideation and behavior among chemsex users with the terms "chemsex", "sexualized drug use", "suicide", and "mental health". Twelve articles (three case reports and nine cross-sectional studies) were included in the final narrative review. Overall, we retrieved mixed results regarding the relationship between chemsex practice and suicidality outcomes. Considering the inhomogeneous nature of the studies, the findings indicate that suicidality could be an issue of concern among MSM in general but among chemsex users in particular. Possible risk factors for suicidality among chemsex participants may include adversities experienced due to one's sexual orientation and an increased risk for HIV and other STI infections and the resulting negative impact on mental well-being. These aspects warrant further investigations.
