I've been reading some of the other posts, and could really use some advice on how to proceed with a situation that we are currently dealing with. In the past year, we realized that my girlfriend's son had a drug problem namely with xanax and marijuana. He was also very verbally abusive in the past, including property damage. We tried counseling, calling the cops, grounding - nothing seemed to work, and from the outside it seemed we were crazy as he's a master manipulator, very charming and smart so no one saw this side of him. Finally, this summer, after close to 5 years of hell, when we were at our breaking point and ready to give full custody to the stepfather (bio dad was in the picture for only a bit, he also has a marijuana addiction), the stepson came to us and said he didn't like the path he was on and wanted to change. He also asked to live with us full time since he felt that the weekends with the stepdad was fueling his addiction, he also came clean about the amount of drugs he was doing and overall, seemed to really want to change. We agreed to let him live with us full time under the condition that he stay clean, sober, and respectful. We immediately got him into a diversion program, which he completed successfully and was clean for about 2 months. He seemed to really be changing his life, he talked about going into the military, was doing better in school, got a job, and even successfully got his driver's license. This all changed about a month ago when after asking us to use the car to go to a movie, he stumbled in at 2, drunk and high as hell. Turns out he never went to the movie, instead he went to a party and decided to drive drunk. The same thing happened on Saturday, he decided to skip out of work (which we let him use the car for) and instead went to another party. Broke curfew and came in drunk and high again; at this time we decided that he wasn't following our rules, he was out. After talking with him, we backed down from kicking him out instead opting for an intensive outpatient rehab program that he would comply with or he was out of the house. There were no if, ands, or buts - any usage and he was out. He thanked us, and said he wouldn't screw up this chance - well flash forward 3 days later to last week, my girlfriend decides to leave work early and he's not home. Well he finally comes home, and is obviously high again. So we call the cops, and since Friday, he has been at a runaway shelter. While in the shelter, he admits that after we told him about the rehab program, he went on a binge and has been smoking pot pretty much nonstop because "he wanted to get it out of his system before rehab started". I'm so confused on what the next step is, he obviously has a problem - do we let him back in under the condition that he does the rehab program? Do we just let go on his own way? We presented the option of an well known inpatient rehab program that he is open to, but I can't help but think that this is all just to avoid being out on the street.
