Myth 1: Smoking looks sexy.

Or at least, that's what the tobacco industry would like you to think. Well, it may look glamorous now, but just wait. Smoking causes deep wrinkles, and yellow teeth are a by-product of years of smoking. Smoking also contributes to osteoporosis, or thinning of the bones, which can cause stooped posture and broken bones—not a pretty picture. In fact, women who smoke reach menopause at a younger age than non-smokers. And, as non-smokers can tell you, kissing someone who smokes is not tasty, let alone sexy.
