Heart disease is the leading cause of death in the United States today, and the leading cause of death among smokers. And, on a global level, researchers report that there were 1,690,000 premature deaths from cardiovascular disease among smokers in the year 2000. In contrast, there were approximately 850,000 lung cancer deaths during the same year, and 118,000 COPD deaths from smoking in 2001, worldwide.
Smoking is hard on the heart, but the fact is, tobacco use plays a role in a multitude of diseases that ultimately lead to disability and/or death. Cigarette smoke contains over 4,000 chemical compounds; 200 of which are known to be poisonous, and upwards of 60 have been identified as carcinogens. Viewed in that light, it's no wonder that the effects of smoking are so widespread and destructive.
Let's take a look at how cigarette smoke affects our bodies, from head to toe. You may be surprised at some of the ways smoking has a negative impact on our health.
