As smokers, we try not to think about the chemicals in cigarettes. Instead, we think about how cigarettes help us cope with the stress of daily life, how they calm us down when we’re angry, help us relax at the end of a long day, comfort us when we’re sad or lonely. Harmful chemicals in cigarettes? No, we do our best to avoid thinking about that.

The truth of the matter is that smoking does the opposite of just about everything we give it credit for. When the chemicals in cigarettes are inhaled, they put our bodies into a state of physical stress by sending literally thousands of poisons, toxic metals and carcinogens coursing through our bloodstream with every puff we take. And those chemicals affect everything from blood pressure and pulse rate to the health of our organs and immune system.

While researchers are still working to uncover all of the hazards cigarettes present to human life, we do know that air tainted with cigarette smoke is dangerous for anyone who breathes it, smoker or not.

Let’s take a closer look at some of the harmful chemicals in cigarettes and how they affect our health.
