Faisability and Efficacity of the Reinforced Communautary Support Program (PARC) on the Complications of Chemsex

The complications associated with chemsex concern infectious disease specialists, addiction specialists, and public authorities. Chemsex is defined among men who have sex with men (MSM) and trans and non-binary individuals participating in gay hookup networks due to their specific psychological, sexual, and social characteristics. The drugs used in France are cathinones (3MMC), GBL, and methamphetamine, administered orally, nasally, rectally, and intravenously (\"\"slam\"\"). Building on change models and health education theories, the teams at 190 and Spot Beaumarchais (AIDES) have created, within their shared facilities, the Parcours d\'Accompagnement Renforcé Communautaire (PARC), a multidisciplinary and community-based program providing comprehensive care for chemsex complications. The program aims to achieve clinical benefits: * Reducing addiction symptoms * Decreasing somatic, psychiatric, and social risks related to chemsex * Exploring and addressing the determinants of consumption and complications, especially psychological and psychiatric * Improving social connections * Maintaining life and professional goals * Perceiving or creating new types of connections between men * Resuming physical activity * Improving self-esteem * Finding a satisfying and fulfilling sexuality * Enhancing overall quality of life The goal of this study is to ensure that the PARC program, as designed, reaches its target population, is feasible, sustainable, at an acceptable cost, and improves the conditions of the population accessing it throughout the course. Thus, in the medium term, this study will identify all success factors for deploying such a program and build a toolkit for its dissemination to other regions with similar issues but somewhat different contexts. The primary objective is to evaluate the feasibility of the PARC program in terms of implementation by measuring patient adherence to the program. The primary outcome measure is the rate of pat
