Since January 22 and until February 9, 700 young people from Essonne and Yvelines are leaving their schools for a day to think about addictions. “We carry out this Décrypt’Addiction action every year,” explains Vincent Grasteau, director of the JDB Cancer Prevention Foundation.

The aim of these days is multiple: to raise awareness, and to try to avoid or delay “first-time consumption of psychoactive products” as much as possible.
