I have consumed cannabis in very high doses for 4 years, and from time to time I mixed it with alcohol. I got to a point when I wouldn't work anymore, I would stay in my room, I wouldn't see anybody anymore. Then someone in my family gave me a book to read C'est quoi la drogue? by Marie-Christine d'Welles. It was like a big slap in my face, I agreed with many things and it was then I decided to stop taking drugs. I remember the last page [editor's note: the psychotropic drugs table]
