E-cigarettes ARE less addictive, study finds - but experts warn long term health benefits are still unknown

We found that e-cigarettes appear to be less addictive than tobacco cigarettes in a large sample of long-term users,' said Jonathan Foulds, professor of public health sciences and psychiatry, Penn State College of Medicine. The popularity of e-cigarettes, which typically deliver nicotine, propylene glycol, glycerin and flavorings through inhaled vapor, has increased in the past five years. There are currently more than 400 brands of 'e-cigs' available. E-cigs contain far fewer cancer-causing and other toxic substances than cigarettes, however their long-term effects on health and nicotine dependence are unknown.
