If you’ve never had a cigarette, you won’t understand. If you’ve had the occasional casual drag or two at a party, this isn’t for you. If you’ve bought a pack, only to smoke one or two a day until you run out, then you have no idea. If you can go weeks at a time without thinking, feeling, or hungering for the sweet inhale of smoke into your lungs, then you don’t get it. If you’re any of the above, you’re lucky. You’re not an addict.
