I didn't say that drugs cause changes in brain chemistry, I said that "addiction" causes long term changes in the way that the brain operates. This is readily apparent if you look at the MRI from a long term meth abuser during the time when they are using meth, during the 6 months after they cease to use, and during the 2-3 year period that it can take for the brain to return to "normal" functioning.
I don't understand why you seem to be taking such offense to the things I've said, but I'm certianly not trying to offend anyone.
Addiction potential (as a clinical term) is defined by a drug's interaction with the mesolimbic pathway. When I say that something causes long term changes, I am speaking of the ability of the brain to regulate its production and distribution of neurotransmitters. Crossing the line from "abuse" into "addiction" occurs when the brain can no longer regulate itself or when it becomes unable to produce a chemical. Behaviorally this results in compulsions, obsession, etc. This is why from a treatment standpoint, addiction is considered to be an obsessive disorder.
I think you are under the impression that I am some sort of staunchly anti-drug person. I'm not.
You don't like AA, I get it. I can respect that. I apologize if I said something that made you feel like I'm attacking your stance. Not sure what else to say.
Oh, and when I say medically treated (or whatever), I'm referring to things such as the use of anti-obsessional meds to help combat drug cravings, the use of benzo's (in a clinical setting) to combat life threatening DT's, open and frank use of methadone programs to treat opiate addiction on a long term basis, the use of needle exchange programs without the social stigma and demonization that occurs in America, ethical accountability to "drug docs", education for parents that want to cram their kids full of anti-depressants. Stuff like that. I also want to try and keep an open mind to the fact that psychiatric or medical assistance can mean life or death for someone that is active in their addiction.
