I have a 17 yr old son that will not stop smoking weed. I have him in a counseling program 3 days a week. It doesn't seem to be working at all. I have been struggling to help him for a few years now. I've taken everything away t.v., cell phone, clothes, bedroom door, sold his car, etc. nothing I do is working. He told me he can't stop. I need some advice. I don't let him hang out with friends, or go anywhere due to his behavior. He will be 18 in 7 months. Any suggestions are appreciated.
