I smoke smarties. XD
In all seriousness, i dont smoke, but i know people that do. Some people just cant handle it. some people can.
my friend has been smoking since he was thirteen (he's 19). he has one stick a day, two on his birthday, and two if the day is really rough, but other then that, he's the pciture of perfect health. well, kinda, but his health problems are not because he smokes, its because he used to run with a gang.
Personally, I dont think they should do it in public places, but what they do in their own home or in places that are close, but not too close to the public is their own problem. its not liek I'm saying they have to go 100 yards away to smoke. but fifteen feet from the entrance is good.
