Vaping is safer than smoking cigarettes, most people would agree.
Because there is no tobacco being burned and because no smoke is being inhaled, vaping does much less lung damage than traditional smoking.
But that doesn’t mean that vaping is safe, by any stretch of the imagination.
Several recently published studies show that vaping seems to be associated with a drastically increased risk of heart attack.
Further, substances like arsenic, chromium, and manganese—all potentially dangerous—are present in the vapor.
Also, e-cig vapor can cause dangerous bacteria to stick to the sides of the airways, another study shows.
Nicotine inhaled in e-cig vapor can also cause DNA damage, according to a study from New York University.
