smoking bad or good?

It has come to my mind alot since last lecture on smoking, i kind of had a idea of smoking being bad for you however it did not cross my mind of how much smoking can effect someone and how flims prevent smoking as being a normal thing all so it has been playing a very big in the society. i have tryed it once and never liked it and after that i never tried it again. personly i could understand why people like to smoke because it could be " being bad "lol however some people smoke to look cool or cannot come of them {even if they know they are bad for you}
