The vapor from e-cigarettes is supposed to be safer than cigarette smoke, but not when it comes to fighting bacteria
There’s quite a bit that we still don’t know about e-cigarettes when it comes to how safe they are — if they cause lung cancer like traditional cigarettes do, whether they are as addictive as cigarettes, and more. That’s reflected by the fact that fewer smokers believe that e-cigs are safer for their health than traditional cigarettes; in 2010, 85% did, but that percentage dropped to 65% in 2013, according to a study published in the American Journal of Preventive Medicine.

But for bacteria, e-cigs may not be so bad. Dr. Laura Crotty Alexander, from the University of California at San Diego and the VA San Diego Healthcare System, found that the vapor from e-cigs prompts bacteria to become more resistant to antibiotics. In the presence of e-cig vapor, for example, methicillin resistant staphylococcus aureus (MRSA) became more resistant to the natural anti-microbial agents that the body makes. Cigarette smoke also produces the same effect, but Crotty Alexander was surprised that the e-cig vapors did as well, given that they were not supposed to contain the health-harming carcinogens that tobacco smoke does.
