IMO their is by principal one clear cut difference.

The pusher´s motive is making a living on other peoples addiction and doing so with a clear calculating mind. Disregarding the fact that he is effectively selling the means for self destruction.

The addict is not primarily motiveated by a wish to gain something on other peoples misery. He is under the influence of a very powerful substance that hugely diminishes his chances of making a moral decision on whether he should / could alter his path of life.

This is, of course, if we are talking about the hardcore pushers / addicted lot.

Selling or smoking some pot once every three months would carry a somewhat different set of arguments.
