There are so many reasons not to smoke.  In my health class we have been talking about the negative effects of smoking.  One of the many dangers and reasons to quit is the nicotine inside the cigarette.  Nicotine is what makes smoking so addicting. Also, smoking kills your heart and lungs.  I think you should never start smoking.  Smoking is very bad for your body, so you are more likely to have a much shorter life.  When your older you may want to smoke because you think it is cool, but remember : smoking is NOT cool.
