Is e-cigarette vapor as harmful as second-hand smoke?

We asked the experts if e-cigarette vapor is more dangerous than second-hand cigarette smoke.

Most of us know second-hand smoke is not healthy for us, but what about the vapors from e-cigarettes?

We reached out to Irina Stepanov, a professor at the University of Minnesota, to find out. Her team studies the effects of second-hand smoke from cigarettes and e-cigarettes.

“Most likely e-cigarettes are less harmful than cigarette smoke. It contains fewer toxins,” Stepanov said.

According to Stepanov, both contain dangerous carcinogens, but there are more in cigarettes.

The bottom line is that both second-hand smoke and e-cigarette vapor are harmful, but we did verify that e-cigarettes are most likely less harmful.

Researchers are still looking into the long term effects of exposure to vapor smoke, which is why Stepanov suggests avoiding exposure to both.
