eCigarettes are controversial. Some people regard them as a major health improvement because they are far less harmful than "real" cigarettes. Others seem to think they are just another way for the tobacco industry to enslave people with an addictive substance.
A recent study was reported by the Los Angeles Times like this:
Teens who vape are more likely to become teens who smoke — and smoke more often
But there have been plenty of contradictory studies on e-cigs and their impact (see, for example, the different answers to this related question: Are electronic cigarettes a healthier alternative to regular cigarettes? ). Is this one consistent with others? Are e-cigarettes a gateway to real cigarettes in teenagers (or any other group forthat matter)?
