I passive smoked growing up and occasionally get cravings just from that. I've only smoked once and I don't want to smoke properly because I'd get hooked so easily.
I've smoked before a handful of times and in the future I could see myself smoking more, just on rare occasions though. I have enough self-control to not get addicted.
Started my freshmen year of high school. I was smoking regularly throughout my sophomore year and first half of junior year, but I finally cut down. Now, it's rare & sporadic.
