I definitely agree that tolerance doesn't stay the same like this post says... An addict can't be sober for 5 years and then use the same amount of DOC without most likely overdosing. I think the point was more that for an addict, use of almost any substance in the future can be a path back downward. Which I've seen as pretty accurate. Many think it'll be okay to replace DOC with something legal but their brain is still recovering.
