it didn't go as planned

Husband is never home when J is.  And when he is J has had "plans".  So - unfortunately - circumstances forced me to start talking to him.  And it wasn't pretty.  Of course, he blew up.  He told me he was the middle man for the prescription drug exchanges (never received $ - which I believe) so that he could receive free pot for making the connections. He told me that he smokes pot "every other day" and he finds nothing wrong with it.  There is nothing wrong with drug traffic-ing?  Said he's able to handle himself and has been working hard to make himself a better person. He was extremely emotional and upset.  I believe he's self-medicating but he said he will not see any counselors or doctors when I told him that all we ask is for him to talk to a drug counselor.  Drug testing?  Forget it.  He said he won't go to school if we make him do that. So we're at a crossroads and not sure exactly what to do.  Our son is extremely stubborn and will most definitely cut off of his nose to spite his face.   I called our friend - the drug counselor and he told me that there is no right or wrong answer and wish he had a crystal ball.  He said we could lift the conditions and tell him that if he finds himself in trouble - he's on his own OR we can draw the line in the sand.  If we decide to send him without conditions, and something happens, we could find ourselves beating ourselves up - asking why we let this go.  On the other hand, if we put out foot down and he leaves - it may give him the excuse to go hog wild and sink even deeper.  **Up until we made the discovery - on the surface - he appeared to be doing "well".  Only time will tell whether or not he can handle himself...  So - I am going to pray for guidance.  My husband and I are leaning toward giving him the opportunity to do school and let the cards fall where they may.
