Jokes or not, a broken back has been the beginning point for so many addicts.. They get pain patches, pills, endless amounts of powerful narcotics.. How silly
also, if you decide to call the cops when you are sure he has dope, he will figure out who told, or at least have a good guess.. I wouldn't recommend it!
The benefits of rehab for someone who hasn't hit bottom yet are, I would guess (i was never forced to go to rehab, I just went once by my own decision, but I know a lot of people who were forced to), are that the seed of idea to get sober, the principles of aa (where most addicts end up for support), they are all started.. Just the idea, even if the person goes right back to using. Although, I have heard of people being sent to rehab 10, 20, 30, 40 times.
How old is he?
My experience of getting sober was to go to an out-of-state rehab center, for 6 weeks (my decision), and then took their suggestion - (doing it my way never worked before!) - I went to a sober house, in a city called new haven, connecticut.. It is a city overflowing with young people getting sober.. There are so many meetings.. So many young people.. It is hard for young people to get sober sometimes when "everyone else" is drinking, smoking, using, etc.
See what you can find online in ways of al-anon material.. Become familiar with the 12 steps and traditions.. (same material more or less for aa or al-anon) .. Try to find an al-anon message board.. I guarantee there are people who have gone through the same things..
Good luck
