I've been wanting to quit as well. It's not that I consider weed to be bad for me, but I definitly smoke a lot more than I have to. My tolerance is so high now that if I want to go to sleep I HAVE to smoke like at least 1.5 grams if I'm smoking that day. It's making me slow, and it's making me a bad conversationist. More importantly it's making me lazy at school. Pot has improved my character and my intellect drastically (if indeed those changes can be attributed to pot), but I smoke way too much for it to have any advantages right now.
