Yeah, when I'm a parent, I will.  I stopped smoking like a month ago, because I got busted, but I used to smoke like 3 times a day.  I don't think I would let my kid do that, but if they wanted to go get high, more power to em.  I'd rather have em out living life to the fullest than living in fear of punishment and not living as a result.  I wouldn't encourage it or even talk about it.  If they discover it, thats chill, if they don't thats chill too.  If I catch them, I might talk to them about limits and make sure they don't try other drugs and stuff, but weed isn't near as bad as everyone says it is.
