Chemsex in Moscow: investigation of the phenomenon in a cohort of men who have sex with men hospitalized due to addictive disorders

Abstract

The present study was designed to investigate the phenomenon of chemsex among Moscow men who have sex with men (MSM) patients who were hospitalized due to various addictive disorders. It was an observational cohort study which included a total of 30 male patients who underwent inpatient treatment at the Moscow Research and Practical Centre on Addictions of the Moscow Department of Healthcare due to various addictive disorders. Data on sociodemographic, sexuality-, sexually transmitted infection- (STI-), and drug use-related characteristics obtained in face-to-face interviews were recorded in all patients. Mean (SD) age of the patients was 24.3 (3.5) years. Mephedrone was the drug most commonly reported as being used for chemsex (over half of cases); it was consumed by 16 patients. Gamma-hydroxybutyric acid/gamma-butyrolactone use was reported by 6.7% of patients; 16.7% of patients preferred cocaine; ketamine use was present only in one patient. Five participants (16.7%) reported the use of other stimulants. Overall, 20% of patients reported their HIV serostatus as positive. Self-reported other STI status was positive in 12 patients (40.0%). Our findings revealed that practicing chemsex among MSM can be considered a trend in Moscow. Our study emphasizes the role of collaborative work of sexologists and addictologists in order to develop and evaluate the interventions.
