I'd have to agree with 18. I started smoking at the age of 11. A friend and I found his stepdad's stash and smoked it all up. Anyhow, the reason I say 18 is because of things like what someone mentioned earlier. Leaving/skipping school to smoke, etc. I believe that it would do a person much better to get school out of the way first. I'm not saying that EVERYONE in school is not capable of smoking and carrying on with a normal life, but I just know how I was when i started smoking. It's all I cared about. I think that I let it cloud my brain a little too much. I'm happy with the way my life is now, BUT it could have been a lot easier on me, had I waited. I don't know what else to type now...I'm well on my way to being drunk. And it's time to roll something!
