Resum

This manual is divided in two parts. The first part presents the definition of chemsex, problematic chemsex involvement, harm reduction in the context of chemsex engagement and some core guidelines regarding best practices when delivering services on chemsex. In order to be properly informed, trainers should study this part before they implement training programmes. Of course, the information provided is not meant to make someone expert on chemsex, only to provide a sound basis on this topic. Nevertheless, expertise, if such a thing exists at all, can only be acquired through continued experience, practice and reflection. The first part of the manual could be also a useful resource for anyone interested in chemsex and chemsex harm reduction. The aim of the manual was not to be an exhaustive scientific review. However, it was based on the scientific, clinical or on the ground experience of many resources. These resources are presented at the end of the manual in the references section, sorted by chapter. For trainers who wish to consolidate their understanding of chemsex, that reference section can also be a useful starting point for further reading. The second part of the manual outlines a training workshop on chemsex and harm reduction. Of course, the proposed workshop will need to be modified to accommodate each specific group of trainees, their needs, the time limits and other resources and limits of each context. All prerequisites, such as necessary materials and detailed guidelines on recommended activities, are given in this part of the manual, so that trainers have the opportunity to be fully prepared to implement the content.
