I'll note that research continually evolves. This is what Mayo Clinic would like people to know about vaping vs smoking.

"First publicized as a safer alternative to smoking tobacco, vaping caught on because it didn't contain the carcinogens or tars found in most smoking tobacco products. Also, vaping was supposed to eliminate the dangers of secondhand smoke to those nearby.

It all sounded pretty harmless in theory. However, those theories were wrong."
