Hell, my dad never said "Don't do drugs", "Don't smoke" or "Don't drink" and I never did because I was raised properly and had common sense. I didn't even have a curfew.
I drink occasionally now, but geez I'm 28, I'm allowed!
Usually, ESPECIALLY with females, when the parents are way to strict, there's more chance for the child to go out and do bad shit. It's alot better when they're not strict. Don't get me wrong, there's a limit, because you can't just let them do whatever they want, but being too strict usually contradicts the point of being strict. Chances are they're not going to be able to take the pressure anymore and just be like, Fuck it. They'll go out, and do who knows what. Or run away from home entirely.
