re: Hmm....
Your work is commendable. If you feel like it, could you elaborate on what you've seen it do to people. In other words, what does a person with a "fucked up brain" look like.
I currently know 4 habitual users. What I see in all four is a lack of ambition and none of them have lived up to their potential imo. I have never seen anyone I would call brain-damaged.
I also knew people in college that got high and were 4.0 students. They became lawyers and engineers. Never really understood that one...
