from my habits, i seems that driving the car and sat at the pc are my main to places for excessive smoking, i say excessive, but in the sense of smoking for smoking sake, and not on the need basis,
As for smoking in tents, I will admit to doing that, but I do try to avoid it, its mainly first thing in the morning when its too chilly to climb out of a warm sleeping bag, and having a last smoke before bed on a night with a drink of some sort..
