How Smoking Actually Mutates Your DNA

Of course, what’s the result of these mutations? A higher risk of developing cancer. In each instance that it happens, there is another chance that the cell will become cancerous.

According to the CDC, cigarette smoking is the leading cause of preventable death in the USA, and accounts for almost half a million deaths, or 1 in every 5.

More than 16 million Americans currently live with a smoking related disease, and over 36 million people smoke. Thankfully, the percentage of people who do smoke has gone down 6% since 2005, but there’s still a ways to go.
