TOKYO, Nov. 29 (UPI) -- A study commissioned by Japan's Health Ministry found that some electronic cigarettes contain up to 10 times more cancer-causing agents than traditional tobacco cigarettes. Some brands were found to include formaldehyde and acetaldehyde.
The study is the latest blow to the e-cig industry, lauded by some as an alternative to tobacco to help smokers quit because the vapors reduce the craving for nicotine.
