I work with Special Needs students and am curious as to his actual IQ, I know you said 3 points away from MR, but there are levels of MR. There are a lot of jobs that do not require people to read or write. Have you looked into Mental Health organizations that offer job training to people with mental limits? I agree that Suboxone is by far the cheaper than drugs and if he is finding money for drugs he can come up with money for Suboxone. Does he have a medical card for insurance and would this help pay for Suboxone? If you have a local college contact them and ask if they have students in the Special Ed. dept. training to become teachers that would tutor him for free just to get the expirence. That would look great when they were trying to get a job themselves. Best of luck I am also the mom of a 20 yr. old addict who is currently in a residential rehab program as well as a teacher so I do understand both sides of your problem. Keep looking for options.
