I currently smoke about 1/4 pack to a pack a day. It's still technically legal to smoke, yet due to societal restrictions, it's now almost impossible to smoke anywhere. And it's for this reason alone that the rebellious teenager buried deep inside of me continues to smoke even though I'm sure I could quit quite easily if I wanted.

I'm not a very consistent smoker in that sometimes I go days without smoking and other times, I can kill a pack in one night. I've never had the insatiable nicotine cravings for cigarettes. Because of this, I've never had any issues flying, even on +12 hour international flights. No patches, no gum, no anything.

I hate the smell of cigarette smoke and if I go anywhere that still has smoking/non-smoking sections of restaurants, I always sit in non-smoking. Sometimes, I'll even go without a cigarette on a layover because I can't stomach the thought of going into a smoking lounge (unless it's DEN's or FRA's because those ones aren't too bad). Even though I don't use smoking lounges every time, I still think it's very fascist of TPTB to be getting rid of them and at such an alarming rate.

Hope this helps.
