Easy to recommend, admittedly not as easy to execute, but if you want teenagers to not use drugs, not get pregnant, not drink, not smoke, etc...they have to be chaperoned. Plain and simple. And any 14 year old worth her salt is going to say but don't you trust me. Better have a good answer ready but chaperone anyway. I don't know up to what age but certainly through age 16....And insist on laws for vagrancy, loitering, truancy, breaking of curfews being written as fairly as possible and then enforced.
