Chemsex entails the consumption of certain forms of sexualised drugs before and during sexual activities to heighten pleasure (1). The United Nations Office on Drugs and Crime (UNODC) has associated substances such as methamphetamine, mephedrone, and gamma hydroxybutyrate (GHB)/gamma butyrolactone (GBL) with chemsex practices (2). In an Asia-wide review, the prevalence of sexualised drug use among men who have sex with men (MSM) ranged from 3.6% to 91.2% (3), with varying rates of chemsex from 3.1% to 30.8% (4). Global literature on chemsex indicated adverse impacts, such as on physical, sexual, and mental health; on users' lives and risky sexual behaviour, such as condomless sex (5).
