I feel you. Personally, with all these kids killing themselves and cutting themselves and shit, I think I'd rather encourage my daughter to smoke cannabis at 16 than take antidepressants. Kids deal with a lot of pressure and shit, and I don't buy into cannabis causing schizophrenia to manifest in still growing adolescents. If they're going to express themselves or do something cathartic, it should be most effective, least self-destructive, and safe. More over, I think coming to an understanding of a kid's autonomy and need to make mistakes would be better done safely with proper guidance, and if a kid can't trust you to be understanding, they just aren't going to tell you shit.
