Weed & Marijuana Addiction Help? Pros and Cons of Smoking Weed?

I've been reading a lot on these yahoo answers about weed and possible mental addiction.

I have been smoking heavily, weed, on a daily basis for the past month and a half. At the highest point of the "high" i feel great and careless but all the other time know i should stop. it is getting in the way of my college studying, job and exercise. i have gained 11lbs.

What can i do to stop smoking weed besides simply stopping?

Any hotlines or any sort of help i can get? thanks so much.

Also, if someone could list the pros and cons of smoking weed.
