A Parisian psychiatrist publishes a book about chemsex. Dr. Jean-Victor Blanc works at Saint-Antoine hospital and teaches at the Sorbonne.

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

In his essay, the doctor combines clinical experience with research. He analyses why chemsex appeals to certain groups. He also examines the social causes behind this phenomenon.

Chemsex refers to drug use during sexual activities. It mainly involves stimulants like crystal meth and GHB. This behaviour occurs mainly in certain 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 problem. It relates to loneliness, sexuality and social pressure. A holistic approach is therefore necessary.
