E-cigs might be less addictive than tobacco cigarettes, but they could be just as harmful to your health, studies say

As e-cigarettes have become more popular, the controversy around them has only grown as well. Former U.S. 

Surgeon General Vivek Murthy declared that e-cigarettes were causing a "public health crisis" amoung young Americans, for example—and a recent study suggested that e-cigarettes could actually decrease a smoker's chances of quitting. At the same time, research has indicated that e-cigarette users inhale fewer cancer-causing carcinogens than cigarette smokers, indicating that vaping may be a safer option.

That somewhat contradictory body of research got a little, well, cloudier this week.
