Don't listen to these untermensch faggots who have a predisposition to destructive addiction. It's entirely within your realm to quit cold turkey if you're not already hooked. Here's a few pro tips:
1) Stop buying: Refuse to go to the gas station and plonk down pounds for fags. Limit yourself to bumming from your friends. Won't that get annoying to them? That's the point; unless you're autistic you will know how they feel and not want to be a burden.
2) Don't smoke the trash in your pic: Smoke Dreams, Nat Shermans, American Spirits, or some other premium cigarette with no added chemicals. You will get more enjoyment out of each one but they will also be notably more expensive. Unless you're a nigger that can't into numbers, this will dissuade you from going overboard.
3) Stash a pack: Put a single pack in the hardest to reach place in your home, whether that's the attic, under the bed inside the bedframe, on a ceiling beam, whatever. Have a small stash of last resort smokes for when times are tough and you NEED one. When you go through a big effort to pull them out, revel in the shame. Then continue the journey to quitting.
Smoking as most people do it is disgusting and pathetic, it's an addiction pure and simple and they don't enjoy it nor is it cool. Tobacco can be enjoyed in moderation but none of your friends will do that with you, and smoking alone is for losers.
