I was having a cig two years ago on March 19th when the ambulance came to pick me up. I was having a heart attack. On the way to Mayo Clinic, I thought, ” I bet I just smoked my last cigarette.” And sure enough, after open heart surgery, it was my last. I don’t even think about them anymore. My wife still smokes, and like the smell of hers, but I don’t want one. The one big kicker was when my 8 yo grand daughter said to me the night before surgery,” Please Grampa, Don’t smoke.” As for the OP, I never did throw them on the ground. I always disposed of them properly.
