Heroin is very, very physically addicting. Where as, let me use the gambling example again, can be very mentally addicting.

Canadien. Reviewed by Canadien. on . Quitting Marijuana Before I start telling you my tales of woe, I'd like to say how much I enjoy smoking cannabis. People who are addicted to alcohol have a problem called alcoholism. I don't neccesarily consider my use of cannabis a problem,but rather something that i enjoy. Maybe however, I enjoy smoking weed a bit too much? Since I was about 18, I have thrown myself into a heavy cannabis usage. I smoke a joint for breakfast, as soon as i wake up, and carry on smoking from there until I go to bed. The last Rating: 5
