When I started smoking, I immediately felt like I was understanding new things, even the first time I successfully got high. I started keeping a journal of thoughts that I called "The Bible" (I was also moving vehemently against Christianity at the time). I found it recently, it covers basically my whole senior year of high school, my age 17 year, and took up the whole notebook... looking back from the beginning, the "theories" were silly Half Baked-style nonsense, the first one was, dude, I just realized the universe can be expressed as the graph y = x^2 + 2, and I drew some pictures of it and shit... by halfway through there were some interesting and coherent ideas, and by the end it was actually pretty insightful sometimes. I really had some strongly psychedelic experiences on weed when I started, that first year. Not the same sort of thing as the next year when I did mushrooms and woke up to realize that I was the eyes of the world

, but it certainly drastically altered my thinking and helped me to move towards a more thoughtful and open-minded place. Of course, I was 17, not 13/14/15/16. Just a year away from college. I wouldn't change anything really, and I was ready for psychedelics at 18 also (going away to college and being in that mind frame was probably really important for that as much as the age).
