Sexuality drugged to the point of addiction? What once seemed marginal is no longer so. The practice of chemsex is no longer confined to gay men. Chemsexers, former chemsexers, Parisian elected representatives, healthcare professionals and community activists all agree that it's time to tackle the issue head-on. Chemsex hides the consumption of stimulating and euphoric substances designed to facilitate, prolong or enhance sexual relations through their psychoactive effects (such as cathinones, including 3-MMC, but also GHB and GBL). Without taboos, thanks to the strength of courageous and intimate testimonials, this film aims to give a concrete understanding of what chemsex is: from the first time to regular practice, from the first effects to the impact on an entire life. It also highlights the methods and help available to deal with addiction and regain control of one's sexuality.
