May 15, 2010 - Researchers from the New York Medical College; Valhalla, NY, demonstrate that 'safe' cigarettes are as hazardous as tobacco.
Using the same technique they developed to document the harmful effects of tobacco products, a team of researchers found that cigarettes made without tobacco or nicotine may be more carcinogenic because they actually induce more extensive DNA damage than tobacco products. The technique has been awarded U.S. patent No. 7,662,565.
