I was just talking to a good friend who is going through a similar situation. His son is a little older (17). My friend has decided to take a tough love, zero tolerance approach. He has told his S that he is not welcome in the house if he is using drugs and has asked him to take regular drug tests.
It is a little easier, since he is happily married and this was a decision he worked through with his wife. I don't envy either of you. This must be incredibly difficult.
