I did about once a week, a little bit of pot at age 18, until the guys I was with wanted me to start paying, so I stopped completely after a month or two, and never did it again. My illness was a gradual thing, and my first doctor said, If you don't get on and stay on meds, you're going to lose your mind. He was right. About ten years ago I stopped smoking cigarettes, and was quitted for more than 5 years, until the big rave was ecigs, and I wanted to try them. Once I did that, just a matter of time before I went with the real stuff.
