^^ wow no offense but that sounded really pathetic lol. Who really cares what parents think.. its not what they say that should matter. its ur own judgement, except when you live under there roof then you gotta act like it matters I guess. My mom knows I smoke weed. she hasn't tried to stop me, all she said was I thought you'd be the last person in the world to do it. well she thought wrong eh!
its a little different to defend drug use to your parents than it is to someone on the street. parents aren't going to change their minds if they think their child has been hurt and corrupted.
You can at least try. The point is to defend yourself and soften the blow. Some parents aren't dumb enough to believe propaganda, and can listen to their kid when he sends them scientific proof about what the drug really is and does.
