Chemsex is associated with higher risks of sexually transmitted infections including HIV, and it has negative effects on mental health and productivity. However, chemsex is under- or un-addressed in most primary care practices, and chemsex users rarely present to specialists in addiction medicine. We hypothesize that an integrative, multimodal training program for urban primary care providers in chemsex identification and harm reduction will increase the proportion of male patients screened for chemsex. We propose a stepped-wedge cluster randomized trial to measure baseline prevalence of screening and determine the effect of training on the relative risk of screening. Screening and appropriate safety counseling can stem the progression of the epidemic and reduce the burden of consequences associated with chemsex. v CHAPTER ONE - INTRODUCTION 1.1 Background 1.1.1 Chemsex Proliferation and Associated Risks Chemsex can be defined as the use of drugs before or during sexual experiences in order to facilitate or enhance the experience1. Typical substances identified in the literature associated with chemsex include crystal methamphetamine, gamma hydroxybutyric acid (GHB), gamma butyrolactone (GBL), and less frequently inhaled nitrates (“poppers”), phosphodiesterase-5 inhibitors (Viagra), and 3,4-Methylenedioxy methamphetamine (“ecstasy”) 2. Chemsex is a distinct form of recreational drug use, with its own culture and language allowing users to communicate, source drugs,
