I agree with you. It's bugged me for a while that there aren't really any explicitly leftist recovery programs. Like AA/NA are based almost entirely on dogma, they might as well be cults. A materialist perspective on addiction looks a lot a bit different. Simplest way I can sum it up is; we use because our lives are bad, we're ALL alienated and unfulfilled under capitalism, no wonder people become writhing husks of excessive consumption.
