Study: Cigarette Smoke Is an Immediate DNA Danger

In a new study funded by the National Cancer Institute on the effects of inhaling cigarette smoke, researchers assert that genetic damage linked to cancer becomes evident within minutes of lighting up.

They say the harm to DNA happens so fast "it's equivalent to injecting the substance directly into the bloodstream."

In fact, one particular type of pollutant, called phenanthrene, that's found in cigarette smoke takes just 15 to 30 minutes to form a substance that is able to "trash DNA, causing mutations that can cause cancer."

Study: Thirdhand Smoke More Hazardous Than Previously Believed

Photo Courtesy - Getty Images(WASHINGTON) -- Thirdhand smoke -- the smoke that sticks to clothing, hair and furniture -- may be more dangerous than previously believed, according to a new study from the American Chemical Society.

The study, published in ACS’ journal, Environmental Science & Technology, found that residual nicotine from thirdhand smoke can form toxic pollutants when it comes in contact with ozone in indoor air.  As a result, babies crawling on carpets, people laying on couches or people eating tainted food could be at a health risk.

Researchers for the study, which was published in ACS’ journal, Environmental Science & Technology, tested how nicotine interacted with indoor air on various materials, like cellulose and cotton, to simulate results on household surfaces.
