No, i haven't smoked, and i've never had the slightest temptation to either, so i was lucky for that. I understand how some kids get a lot of pressure from their friends to do it, so i don't blame anyone who tries it or anything. If you get addicted to smoking because you were pressured into it, then that is highly unfortunate, but i think most people make their own mind up about smoking. If you decide to do it, nobody can tell you you shouldn't. It'd certainly be better for you if you didn't, but it's up to you. ;)
As others have said, i don't understand why people want to smoke. I find it hard to believe it tastes good too. I don't really know anyone who smokes, so luckily i'm not often around people who are smoking, because even breathing in their smoke is bad. Come to think of it, when my Pa was younger he smoked for a couple of years i think, and then quit cold turkey. Even though he only did it for a little while, there has been some damage to his lungs.
