Actually, I go to a technical school that emphasizes hands on and "real world" experience. Though, this is irrelavent from the subject.
Maybe we're going on about two different things. I'm trying to clarify on the term "addiction". What are you trying to do? If I'm wrong, then I'm wrong. It would leave me wanting to know the clarification of the term "addict" or "addiction" better. Telling me that I don't know what I'm talking about because I haven't smoked pot on a regular basis won't do any good. There are psychologists out there that never smoked pot but they can still clarify what abuse, dependence, and addiction is.
