Cigarette Smoke Delivers Approximately 1500 Times More Harmful and Potentially Harmful Constituents (HPHCs) Than Vapor OR Air!

Analysis of the smoke from conventional cigarettes showed that the mainstream cigarette smoke delivered approximately 1500 times more harmful and potentially harmful constituents (HPHCs) tested when compared to e-cigarette aerosol or to puffing room air.

Of the 55 HPHCs tested in aerosol, 5 were quantifiable in an e-cigarette sample. The five analytes which were quantifiable were statistically different (p < 0.05) at levels 50–900 times lower than the cigarette smoke samples. Phenol was quantified in one e-cigarette product at 900 times lower than cigarette smoke. N-Nitrosoanatabine was quantified in one product at 50 times lower than cigarette smoke. Three carbonyls (acrolein, acetaldehyde, and propionaldehyde) were quantified at 86–544 times lower than cigarette smoke.

This study supports the notion that vaping is 96-99% safer for humans than smoking.
