Female Speaker: Is there a problem with smoking if I only do it occasionally? Gwendolyn Fancavillo: Smoking even just for social reasons or occasionally in your life is still can be addictive. Nicotine is more addictive than heroin. So even though, you're only smoking occasionally, it's still can impact your body. You're going to get the effects of smoking, stinky clothes, yellow teeth, bad breath and then long-term effects of lung cancer or heart attacks. So even just occasional smoking can still be additive and impact your body in a negative way.
