Sorry Elaine, but I really can't vote in this poll due to the lack of an appropriate choice. For me it was boredom. Literally. I was fifteen, and had a summer job on a really quiet and isolated private island - doing dishes. One older sister was the family's nanny, one was the cook, and I, the youngest, was the dishwasher. So I had long summer days with nothing at all to. I started by stealing a cigarette or two from the pack of someone in the household who smoked, and sneaking off to be by myself to smoke them. Did that a few times, and within days I was buying packs for myself via ferry trips to the mainland on my day off.
