Lighthouse Learning Series: Chemsex 101

Starting in October 2023 and running until February 2024, we will be covering a series of queer harm reduction topics with the goal of creating a more inclusive movement.

Priority is given to those living and working in New York due to program scope. However, the series will be held virtually and is open to all those who would like to build on their harm reduction knowledge to provide better services to LGB/TGNC+ folks!

Session description: In this interactive session, Chemsex and substance use within the queer community will be contextualized using epidemiology and syndemic theory. Principles of motivational interviewing and healing-centered care will be applied to engaging and affirming people who participate in Chemsex. Common Chemsex substances will be reviewed, myths and truths discussed, and general and substance-specific harm reduction/safety interventions will be learned and practiced. The session will conclude with policy and advocacy work needed to support people who participate in Chemsex.
