The worst experience I had was that I smoked waaaaay too much and felt like I was going to throw up. I wandered into the bathroom , laid down and fell asleep on the floor. Woke up a couple of hours later and was fine. Only happened once.

I didn't try weed until I was 18 and already graduated from High School. I stopped smoking weed in January after 7 years of heavy daily smoking. I've noticed no long term effects that I can tell. I've always been a functioning stoner..always held down a job, made weed a secondary priority..my lung function has improved a bit because I've stopped having the 'chronic cough' but other than that, everything is the same. I miss it...I plan to go back to it eventually. Just don't have room in my life for getting stoned right now.
