I can offer what finally seemed to help my son. Although he was not adopted, I see similarities. He too started using weed in 9th grade and all quickly began to fall apart. School, friendships, sports, family relationships, etc. We intervened pretty quickly and nothing seemed to work. Fast forward 18 months and he was brazen enough to smoke in our home time and time again. We punished him over and over again but he kept using. The final straw was when I read a text message on his phone where he was planning to buy weed. I turned off his phone service and when he found out what I did, he completely lost his cool. Yelling, cussing, and ultimately broke a window, my glasses and 2 cell phones. Right there and then I called the police. They suggested we go to the courts and file charges. We did and since he had never been in trouble before, the probation officer put him on a diversion plan. That plan included 10 weeks of anger management, substance abuse class for 10 weeks, 50 hours of community service, weekly sessions with a family therapist and random drug screens. We completely handed the consequences over to the court. That was an important piece as it removed the battle from between us. Also, all but the family therapy was paid for by the courts. That also was important because we have tapped out our financial resources in getting him previous treatment. As long as he met the all of the conditions of the diversion plan, it falls off his record. It has never has to be reported to anyone (ie, employers, school) because the idea is to give him a fair chance to make life long changes. Through all of these programs, he has begun the long path to change. It was by no means a perfect answer but it certainly scared him to see that we were no longer going to protect him from his choices. I can't say he thanks us, actually he is very angry. But he made honor roll for the first time since starting weed, and most important he is no longer smoking and engaging in scary reckless behavior. Because he is clean, he is also able to really start digging deep and dealing with why he felt he needed to self medicate.
