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

Mephedrone and chemsex: when it stops being a party and becomes a fatal problem

Chemsex is the use of psychoactive substances, mainly gamma-hydroxybutyrate, 4-methylmethcathinone (mephedrone), and methamphetamines to facilitate and enhance the experience of sexual intercourse. The toxicity of these drugs may be problematic and lead to a fatal outcome in some patients. We present the case of a 26-year-old man living with human immunodeficiency virus whose frequent use of mephedrone caused his death.

Let’s talk about chemsex and pleasure: the missing link in chemsex services

Purpose

The purpose of this paper is to document the experience of current and former methamphetamine users on their crystal meth use patterns and on their use of services related to their chemsex practice.

Design/methodology/approach

For qualitative component, two focus groups were formed with nine current users of methamphetamine and eight former users. Thematic analysis was performed to know their experiences.

Findings

All participants were already engaging in chemsex with various substances before they first started using methamphetamine. Methamphetamine use led some to slam (methamphetamine or mephedrone injection). Some participants report that their sexual experiences were intensified early in their chemsex practice. They reported feeling more confident with their partners, feeling like they are sexually attractive and overcoming their barriers to sexuality. The intensification of methamphetamine use and, in particular, injection change the positive perception of sexual life. Thus, for some participants, substance use takes more space and their sexual experiences become less satisfactory.

Practical implications

Participants report the services that address the phenomenon of chemsex are still scarce in Quebec province. In addition, the few services available aim to relearn a sober sexuality. However, the mourning of the positive aspects of chemsex on sexual experiences seems still very little discussed. Greater consideration of positive chemsex experiences is needed in services that address this issue.

Originality/value

This project documented the perception of pleasure related to sexual practices among regular methamphetamine users. Their perception of pleasure will help develop services adapted to their reality.

Acute and repeated administration of MDPV increases aggressive behavior in mice: forensic implications

MDPV is a synthetic cathinone illegally marketed and consumed for its psychostimulant effects, which are similar to those produced by cocaine, amphetamines, and MDMA. Clinical reports indicate that MDPV produces euphoria, increases alertness, and at high doses causes agitation, psychosis, tachycardia and hypertension, hallucinations, delirium, hyperthermia, rhabdomyolysis, and even death. In rodents, MDPV reproduces the typical physiological effects of psychostimulant drugs, demonstrating greater potency than cocaine. Nevertheless, its role in aggressive behavior has been reported but not yet experimentally confirmed. Therefore, the aim of this study was to evaluate the effects of acute and repeated MDPV (0.01-10 mg/kg i.p.) administration on aggressive behavior in mice and to compare them with those of cocaine (0.01-10 mg/kg i.p.) administration. To this purpose, the resident-intruder test in isolated mice and the spontaneous and stimulated aggressiveness tests for group-housed mice were employed. The present study shows for the first time that MDPV enhances aggressive behavior and locomotion in mice with greater potency and efficacy than cocaine treatment. Moreover, the aggressive and locomotor responses are enhanced after repeated administration, indicating that a sensitization mechanism comes into play. These results, although from preclinical investigation, are suggestive that human MDPV intake could be a problem for public health and the criminal justice system. Thus, investigation by police officers and medical staff is needed to prevent interpersonal violence induced by the consumption of synthetic cathinones.

Online Intervention as Strategy to Reach Men Who Have Sex With Other Men and Who Use Substances in a Sexual Context. Development of the MONBUZZ.ca Project

Men who have sex with men (MSM) use more psychoactive substances and a greater variety of them compared to their heterosexual peers. In this population, substance use is particularly characterized by polydrug use, binge, and sexualized substance use. MSM who use substances do not recognize themselves in public health messages targeting substance users. In addition, they recognize their problematic substance use later than heterosexuals and, as a result, they use addiction services later in their addiction trajectories. When accessing addiction services, the links between drug use and sexual life are rarely considered. Because of this profile, online interventions are a promising way to reach this hard-to-reach population. Currently available online interventions targeting MSM address the topics of substance use and sexual life separately. To deal with this situation, our team wanted to develop an online intervention platform for MSM who use substances in a sexual context. Given that online addiction interventions do not address sex and that MSM drug use is highly related to sexual activity, we first explored the literature related to online interventions targeting MSM and HIV risk behaviors, as well as online interventions targeting general population in order to: (1) identify relevant (or personalized) intervention methods; (2) describe the approaches used; and (3) describe their effects. Second, we turned to the literature to develop the MONBUZZ.ca project in collaboration with community organizations. The results of the narrative review provided a critical portrait of online interventions for MSM and guided the development process of MONBUZZ.ca. We discuss issues of co-development of a research and brief intervention tool based on promising practices as well as challenges of its implementation and evaluation.

Ultra-High-Performance Liquid Chromatography Tandem Mass Spectrometry Assay for Determination of Endogenous GHB and GHB-Glucuronide in Nails

Background: The short chain fatty acid gamma-hydroxybutyric acid (GHB) is a precursor, and the metabolite of gamma-aminobutyric acid is commonly used as an illegal recreational drug of abuse. Methods: An ultra-high-performance liquid chromatography tandem mass spectrometry was developed and validated for endogenous GHB and its glucuronide in nails, to complement hair in forensic contexts for a retrospective detection of psychotropic drugs consumption. Results: GHB endogenous values for children and adolescents, adult females, and adult males in fingernails ranged from 0.3 to 3.0, 3.2, and 3.8 ng/mg, respectively, and toenails values ranged from 0.3 to 1.8, 2.0, and 2.4 ng/mg, respectively. In the three different groups, values of GHB in fingernails were statistically higher than those in toenails. GHB glucuronide could only be detected in finger nails with values ranging from 0.08 to 0.233, 0.252 and 0.243 in children and adolescents, adult females and adult males, respectively. Conclusions: The validated method was efficaciously applied to real finger and toe nails specimens from a population of males and females non GHB consumers. A preliminary cut-off of 5.0 ng/mg nail for endogenous GHB and 0.5 ng/mg for endogenous GHB-Gluc in the general population was proposed.

Effect of sildenafil citrate on the liver structure and function in obstructive jaundice: An experimental study

Objective

We aimed to investigate the effect of 10 mg/kg sildenafil on the structure and function of the liver in a rat model of obstructive jaundice.

Material and Methods

Sixty-two male Wistar albino rats were distributed into six different groups. Obstructive jaundice was performed by legating the common bile duct. 10 mg/kg sildenafil citrate in drinking water was delivered orally after the operation before sacrificing them. Rats were sacrificed either after 10 or 28 days according to the study design. The blood and tissue samples from the liver were obtained to perform a biochemical and histopathological analysis to study functional and structural changes in the liver.

Results

At the 10th day, there was no difference between the sildenafil-treated and control groups with regard to the aspartate aminotransferase and alanine aminotransferase levels (p=0.423, p=0.661). The alkaline phosphatase total bilirubin levels among the groups were statistically different (p<0.001). At the 28th day, liver function tests except alanine aminotransferase showed significant differences among the groups (p<0.001). Liver function tests did not changed significantly between the 10th and 28th day in sildenafil-treated rats (p>0.05). Significant differences were observed among the groups with regard to cholestasis, fibrosis, inflammation, and necrosis (p<0.001). However, edema increased in the sildenafil-treated group (p<0.001). On the 28th day, the severity of structural changes in the liver after obstructive jaundice, except edema, reduced significantly (p<0.001). The sildenafil-treated groups at different time points didn't show any statistical difference in histopathological changes (p>0.05).

Conclusion

Oral administration of 10 mg/kg sildenafil citrate dramatically reverses the biochemical and histopathological liver changes induced by obstructive jaundice in rats.

Association between recreational drug use and sexual practices among people who inject drugs in Southwest China: a cross-sectional study

OBJECTIVE

To describe the differences in sexual practices among individuals with various drug administration patterns.

SETTING

A detoxification centre in Southwest China, a part of the Chinese national sentential surveillance network for hepatitis C virus (HCV), HIV and syphilis infections, was recruited.

PARTICIPANTS

A total of 610 newly enrolled injection drug users (IDUs) from detoxification centre were included during 2015.

PRIMARY AND SECONDARY OUTCOME MEASURES

Self-reported sexual activities, drug-related practices and laboratory-confirmed HCV, HIV and syphilis infection status were collected.

RESULTS

Of the 610 IDU, 295 (48.4%) used heroin only, 277 (45.4%) poly-drug users reported the mixed use of synthetic drugs (SDs) with heroin and 38 (6.2%) used SDs only. The average daily drug injection frequency for poly-drug users (3.3±1.2 times) was the highest, followed by heroin-only (2.2±0.8 times) and SD-only users (1.2±0.4 time). SD-only drug users reported the highest proportion (86.8%) of engaging in sexual activities in the previous month, with more than half (54.5%) reporting any condomless sex. A higher frequency of daily injecting in heroin-only users was significantly correlated with the less likelihood of sex, condomless sex in the past month, having sex with fixed partners, condomless commercial sex in the previous 12 months (all p<0.01). In poly-drug users, who injected drugs two times per day was associated with the highest proportion of people who engaged in sex and commercial sex (p<0.05). For SD-only users, increased drug use was not associated with reducing sexual risk (p>0.05). Different patterns of HCV, HIV and syphilis infections prevalence rates were shown among the IDU depending on the roles and length of exposure.

CONCLUSIONS

The daily drug injecting frequency of heroin-only and poly-drug users was negatively associated with sexual activities, but SD-only users kept a high frequent engagement in sex. The interventions for relevant diseases should adapt to characteristics of IDU.

A comparison of self-reported sexual effects of alcohol, marijuana, and ecstasy in a sample of young adult nightlife attendees

Alcohol, marijuana, and ecstasy (3,4-methylenedioxymethamphetamine [MDMA], 'Molly') are among the most prevalent substances used by young adults; however, few studies have focused on the specific sexual effects associated with use. Examining subjective sexual effects (e.g. increased libido) associated with use can inform prevention efforts. Data were analysed from 679 nightclub and dance festival attendees in New York City (ages 18-25) to examine and compare self-reported sexual effects associated with use of alcohol, marijuana, and ecstasy. Results suggest that compared to marijuana, alcohol and ecstasy were more strongly associated with heightened perceived sexual effects (i.e. perceived sexual attractiveness of self and others, sexual desire, length of intercourse, and sexual outgoingness). Increased body and sex organ sensitivity and increased sexual intensity were most commonly associated with ecstasy use. Sexual dysfunction was most common while using alcohol or ecstasy, especially among males, and females were more likely to report sexual dysfunction after using marijuana. Post-sex regret was most common with alcohol use. Alcohol, marijuana, and ecstasy each have different sexual effects; therefore, each is associated with different risks and benefits for users. Findings can inform prevention and harm reduction as young adults are prone to use these substances.

Chemsex as edgework: towards a sociological understanding

Sexual sessions between men, organised through mobile technologies and combined with stimulants intended to extend and intensify the session have been reified into the phenomena of ‘chemsex’. Understanding chemsex requires multiple levels of analysis and interpretation. This paper considers chemsex through the lens of edgework, a sociological category for voluntary risk taking identified in 1990 by Stephen Lyng. Edgework activities involve a clear and present danger to the self, intense emotions and sensations and an opportunity to exercise specialist skills. Using published research and other cultural products, this paper demonstrates that chemsex fully exhibits all the defining features of edgework. Chemsex is then positioned as an activity that epitomises the (gay) citizen as consumer in a technocapitalist age of pharmacopornographic consumption.
