I dunno I went through the teenage years with the weed drugs booze cigarettes, caffeine..then I got away from most of it..then later I went back to it..

I think we all get many opportunities to get into all this stuff, and we have opportunities to get out of them, so I think sometimes its more a question of your choices and decisions that define your life more than whether or no you try or smoke weed /do other drugs/whatever....

I think its important to strongly inform them about addiction, control over one's self, their options and choices...

You can be a hardass if you want , but in most scenarios I doubt it will be effective..

Oh BTW I have a kid..one, anyway......
