<p>Smoke if you want. But don't try to pretend there aren't real risks, even if you only smoke "once in a while." </p>
<p>I say this as someone who watched both of her parents struggle with diseases that they definitely would not have had if they hadn't smoked. </p>
<p>My mother had her larynx removed due to cancer when she was 45. No "genetic" link to cancer in her family, it was 100% the years of inhaling smoke since she started smoking at age 16 that caused her throat and layrnx cancer. She spent the next 25 years breathing through an open hole in her neck and not being able to talk except by "burping" out sounds. Both were quite sexy. </p>
<p>By the way, after 25 years the cancer returned, even though she no longer smoked, along with a cancer-related neurological disease that eventually paralyzed her, confining her to a wheelchair and dependent on me for help to do even the simplest things like poop. (You haven't lived until you need to give an adult an enema and track the results)</p>
<p>She couldn't understand how the cancer had returned because she no longer could smoke (difficult to do through a hole in your throat). The cancer specialists we took her to told her that there was no doubt that the second bout with cancer and the neurological consequences were related to smoking, even though she hadn't smoked in 25 years.</p>
<p>My father was a star athlete in high school. Started smoking "just one every once in a while" when he was in the army. By his 30's, when I was born, the "one every once in a while" had become a pack a day habit. By the time he was 50, he had emphysema. No genetic link of this in his family. It was entirely caused by the cigarettes. By the time he died 20 years later, his bones were so brittle from having to take steroids for years just to keep breathing that he once fractured his wrist just brushing it against the kitchen counter and he hadn't been able to leave the house for several years because he needed to be hooked up to a full tank of oxygen and couldn't walk more than a few feet at a time. </p>
<p>I run a non-profit organization for people with cancer. I have talked with literally hundreds of lung cancer patients. I have never met a lung cancer patient who hadn't been a smoker at some point in their lives. I have researched lung cancer extensively and only in very rare cases does it affect folks who don't smoke. Usually, those cases are people who lived with smokers. There has never been a genetic link found related to lung cancer, but there IS a well-substantiated link, based on thousands of research studies, linking lung cancer with smoking. </p>
<p>Oh, I almost forgot to mention. I suffer from severe asthma. Have since I was a child. I have never smoked, but have been asked many many times by doctors trying to help me get my asthma under control if I had parents who smoked when I was a child. They all nod knowingly when I say yes, my parents smoked, because my lungs clearly show signs of smoking-related scaring even though I have never smoked myself. So, even if you don't care about what you are doing to your body, you can be affecting someone you love.</p>
<p>So, smoke if you want. Just don't fool yourself that the pleasures of smoking are worth the risk of ending up like my parents and the other folks I know who have been affected by smoking-related diseases. It isn't. </p>
<p>(And yes, I fully expect that people will tell me that it isn't going to happen to THEM. Same thing my parents said when my sister and I used to beg them not to smoke.)</p>
