According to the article: "UCR professor of cell biology Dr. Prue Talbot and her team discovered the chemicals used to refill electronic vapor cigarettes (e-cigarettes) may be more harmful than tobacco cigarettes. Her team discovered that electronic vapor requires a consumer to take deeper breaths which may potentially draw in harmful chemicals to fragile parts of the lungs, as opposed to a tobacco cigarette that burns on the other end, allowing the consumer less inhalation. “Our earlier studies with electronic cigarette refill fluids showed that some of these products were toxic to both mouse neural stem cells, (and) human embryonic stem cells as well as to adult lung cells,” she said in ."

"Smoking is no more hazardous than taking an exam in terms of its acute respiratory effects."

It is important to point out that just because the relative risk of cancer associated with filtered cigarettes is lower than that for non-filtered cigarettes, it does not necessarily follow that switching from a non-filtered to a filtered cigarette will reduce one's health risks. It is possible that smokers who make such a switch will compensate because they are used to higher tar levels. It is possible that the observed reduction in cancer risk only holds for lifelong filtered cigarette smokers, as they do not compensate (they never smoked non-filtered cigarettes). In fact, the scientific evidence supports this contention.

The rest of the story is that new data from the CDC itself show that the smoking rate among U.S. high school students dropped significantly in 2013, reaching the (the Youth Risk Behavior Survey), which began in 1991.
