Cannabis increased my mathematical and creative writing skills. Especially math. I can't explain it, but man, the combination of being stoned and trigonometry and Calc 1 was just awe-inspiring. I missed the first six weeks of trig because of a scheduling error, and when I did finally join the class, I was in *way* over my head, was sure I was going to fail. But the more I smoked, the more I understood. Caught up with the class, then pretty much passed 'em by, ended up getting not just an A but an A+. I might very well have failed and given up on math entirely if it weren't for pot.
