My son just turned 16 and he's not a bad kid. I mean, he's had some detentions here and there, but has never been in any serious trouble. He's been bringing around a friend who seems like a bad seed. I suspect his friend smokes pot and I definitly don't want my son getting into that.
It would be unfair to come out and say he can't hang out with his friend because I have no proof. Any ideas on how I can find out if my son is doing drugs?
