The Paris clinician Jean‑Victor Blanc, who co-founded the Pop & Psy festival and works in public psychiatry, published the book Des amours chimiques on 3 April. In his clinical practice he treats patients harmed by chemsex, and he frames the practice as both a medical issue and a social signal about the state of gay mental health. Here, “chemsex” is described as the intentional use of psychoactive substances to intensify sexual experience, often with synthetic drugs such as 3‑MMC, GHB and ketamine, and sometimes accompanied by injection or “slam“.
Blanc’s account insists that the phenomenon cannot be reduced to moral panic: it is a clinical reality that reveals layers of silence, stigma and trauma. The combination of taboo around sex, the long‑standing stigma of homosexuality, and the criminalized or hidden nature of drug use delays help‑seeking. For many patients, shame and secrecy are primary obstacles between problem recognition and access to care, which in turn makes the epidemic harder to address collectively.
Origins and the social context
Patients in Blanc’s clinic often share early life experiences that leave them vulnerable. Many men reported childhood shame about desire or masculinity, episodes of bullying or family rejection linked to sexual orientation, and a striking prevalence of sexual trauma — roughly a third in his series. Socioeconomic and identity factors also matter: those who are more precarious, older, or racially minoritized face amplified risk. At the structural level, dating apps and geolocation platforms have normalized rapid partner matching, and the arrival of new synthetic substances and the normalization of injection practices have changed the dynamics of sexualized drug use.
Clinical features and harms
When chemsex becomes damaging, it typically meets familiar criteria of loss of control: the consumption disrupts work, relationships, physical and psychological wellbeing. Clinically observed consequences include addiction, depressive disorders, anxiety, suicidal ideation and even psychotic episodes. There is a heightened risk of sexually transmitted infections and bloodborne viruses in contexts of unprotected sex and injection. The acute danger of GHB overdose — which can lead to coma and is a frequent reason for emergency admissions — is another recurring theme in consultations.
Slam, sexual violence and medical complications
The practice of injection, called “slam”, raises both dependency and infection risks because it accelerates tolerance and compulsive use. Blanc notes clinical patterns such as combining drugs that impair erection with erectile medications to maintain function during sessions, a combination that increases cardiovascular and other health risks. Surveys and pharmacovigilance data reported by French authorities document hundreds of complications: an agency report logged 563 cases linked to sexualized drug use, with roughly 40% classified as severe and 15 deaths — figures that are likely underestimates. Sexual violence is also common during chemsex encounters, with a substantial minority of users reporting assault during sessions, a fact that deepens trauma and isolation.
Treatment pathways and policy responses
Because the practice sits at the intersection of sex, identity and drugs, entry into care often requires multiple, de‑stigmatizing routes. Blanc highlights organizations such as peer associations, groups like Narcotics Anonymous, and infectious disease teams as accessible gateways, alongside specialized addiction and mental health services. In line with modern addictology, treatment goals are individualized: some patients pursue harm reduction or moderated use, while others aim for full sobriety. Yet truly effective responses also demand better training for general practitioners and pharmacists so that front‑line professionals recognize and respond to the problem without judgment.
Community action and hope
Blanc argues that solutions cannot be imposed only from outside the gay community; a collective, watchful approach from within is essential. Community networks can support vulnerable individuals, reduce stigma, and improve reporting and prevention of sexual violence. Cultural efforts — festivals, film programs and open conversation about mental health — are part of reshaping social attitudes. Public health initiatives are evolving too: a national sexual health strategy has been informed by expert reports, and political actors have signaled interest in incorporating these findings into policy. For clinicians and community leaders alike, the message is pragmatic and humane: recognize the complexity of chemsex, reduce shame, expand access to care, and combine individualized treatment with collective support to reduce harm and save lives.
