I've smoked cigarettes for 7 years, and I quit. Marijuana is the farthest thing from addictive I've ever seen...sure I want to smoke it, but that's just because it makes me feel good, not that I HAVE to smoke it...I had a harder time stopping drinking soda pop than I ever have the many many times I've broken regular pot use. Just like that, no withdrawal, no psychological problems or appetite problems...damn I love pot.
