This presentation will describe the phenomenon of Chemsex, namely the use of substances (primarily GHB, methamphetamine and mephedrone as well as other substances) in association with sexual behaviour in Gay, Bisexual and Men who have sex with Men (GBMSM). The relationship between the concept of minority stress as a developmental explanation for the increased rates of mental health problems, addiction and substance use in GBMSM will be explored, including in relation to mental health outcomes, including the intersection between Chemsex and other vulnerabilities. Persistent Methamphetamine Psychosis (pMAP) will be described and emerging evidence as to whether this is a distinct diagnostic entity to other forms of psychotic illness. Finally, the emerging association between Chemsex and offending behaviour will be described through presentation of a number of cases and the challenges they pose for the legal system.
