A Paris-based psychiatrist publishes a book on chemsex. Dr. Jean-Victor Blanc works at Saint-Antoine Hospital and teaches at the Sorbonne.

Blanc leads one of few clinics specialising in chemsex. His book 'Des Amours chimiques, le fléau du chemsex' launches on 3 April with Seuil publishers.

The physician combines clinical experience with research in his essay. He analyses why chemsex appeals to certain groups. He also examines social causes behind the phenomenon.

Chemsex refers to drug use during sexual activities. It mainly involves stimulants like crystal meth and GHB. This behaviour occurs particularly in gay and bisexual male communities.

The doctor warns of serious health risks. Addictions, infections and psychological problems are possible consequences. Blanc calls for more attention and better support services.

His research shows chemsex is not simply a moral issue. It connects to loneliness, sexuality and social pressure. A holistic approach is therefore necessary.
