The Mazan mass rape trial has led to a significant increase in calls to a Paris hospital's call center for victims of chemical submission. Leila Chahouachi, the head pharmacist, assists victims like Gisèle Pelicot, whose ex-husband was convicted of drugging and recruiting men to rape her. The center analyzes hair samples for drug traces and has seen a 69% increase in calls from the previous year, primarily from women aged 20-29. The trial has also prompted healthcare professionals to seek training to better identify such cases, and the French government plans reforms to support victims.
