Have not touched one in 2 years. Went to the dr 2 years ago for a little cough, she did a few tests and my lung volume was 1/3 of what it should have been. Of course her being my Dr since the age of 18, she told me I might have the big E, and sent me for some more tests at a lungh Dr. Well come to find it I do not have it, and ony had a touch of a infection. But I walked out of her office that day open the door to my truck walked back in and handed her a brand new pack of smokes i had just bought and it is the last time i have ever smoked. I asked her a few weks ago when i was in there if she remembes that, she smiled and walked off. I thought it was rude of her but who am I to say she is a busy Dr. Well she came back a few min later and handed me the same pack I gave her, only she wanted me to throw them away.
