My (now) brother-in-law sold acid when we were in high school, and there was a point of time in our senior year where he took acid almost daily for 2 or 3 months. If you'd asked me to describe him in one word when we were 20, i'd have said 'burnout'. Believe it or not, he's fine today. He quit doing drugs in his early 20s after he got arrested, got a business degree, and hasn't touched them in 15 or 20 years. You'd never guess that he's done acid a hundred times or more by talking to him.
