I'm no expert, so I hesitated to answer. However I feel for your plight, and want to help in so far as I can. Nic Sheff wrote Tweak, and his journal is still online at: nicsheff.blogspot.com/ s father David Sheff also wrote a book, "Beautiful Boy: A Father's Journey Through which tells the same events seen through his eyes.
He has a website at davidsheff.com/ with articles and pointers to resources. The only treatment center that is listed by David Sheff is Hazelden (http://www.hazelden.org/), and Nic certainly spent many months there. I think this is the one you are looking for, but I can't be 100% certain as Nic may have spent time in other centers as well.In David Sheff's book, he is told by the Director of the Herbert House Sober Living facility in Los Angeles|LA that "Hazelden is expensive, but it's as good as they come".
Everything that I've seen suggests Hazelden is one of the very best in its field. (But again, I'm no expert, so you should check it out for yourself, and maybe consult specialists.) From what I do know of Drug Addiction|addiction, the biggest problem is not getting off, though that is often hard enough, but staying off. I once heard someone (a former addict turned therapist I think) say something like: "A normal person's life is like a box with many compartments.
Work, family, friends, hobbies, and so on. For an addict, every compartment is filled with their addiction. Everything in their life is connected with and built around the addiction.
Take the addiction away and they are left with an empty, empty life. And the pull is to go back and fill up those boxes with the addiction again". They said the key to staying off long-term is to find something else to fill those empty spaces.
So there is one thing I've across that sometimes help people do just that, and it is described here: http://secondhandaddiction.blogspot.com/2008/08/codependency-second-hand-addiction-and.html http://www.huffingtonpost.com/diana-odasso/my-landmark-experience_b_105502.html This may be an option if you are running out of mainstream treatment ideas. I have heard of it helping people kick a heroin addiction, and have met people that overcame the traumatic effects of having suffered child abuse through this programme. It's not specifically a drug programme, but as you've tried so many of those and are looking for new possibilities, this may be one to at least explore.
Best of luck to you and your son.
Nic's father David also wrote a book called "Beautiful Boy" From what I have read it sounds like the Hazelden in Oregon was Nic's 5th and final treatment center. You can find more information here. hazelden.org/ youtube.com/watch?v=m77f1I_AexU The Book is online in the link below, which is where I found the answer.
Hazelden, including the the Oregon facility is an outpatient care facility so that is something to keep in mind for your son. hazelden.org/web/public/springbrook.page.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
