It's made me a 10000x happier, even when I'm not stoned. My IQ has gone up 17 points since before I smoked, I've been sick a lot less (though I doubt that has anything to do with it), and I concentrate a lot better when I'm stoned.

I suck at math, I'm in Geometry. I am sober and don't understand a word, I get stoned, go in for a test, and at least I get a passing grade.

It's a wonderful thing.
