Study: E-cig vapors contain cancer-causing chemicals

Electronic cigarettes contain two previously undiscovered probable carcinogens in their vapor, according to a study in the journal Environmental Science and Technology.

The Washington Post reported propylene glycol and glycerin were found among 29 other chemicals in the vapor. Study co-author Hugo Destaillats said the findings cast doubt on the perception of e-cigs as a safer alternative to traditional cigarettes.  

“I would say, that may be true for certain users—for example, long time smokers that cannot quit—but the problem is, it doesn’t mean that they’re healthy. Regular cigarettes are super unhealthy. E-cigarettes are just unhealthy,” Destaillats said.
