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 […]

These guys took samples of throat and lung cells and exposed them to hours of cigarette smoking vs vaping. Every hour, an average of 20% of the cells exposed to cigarette smoke died.

Because EC do not burn tobacco, they may be safer than conventional cigarettes. Their use is rapidly increasing worldwide with little prior testing of their aerosol. OBJECTIVES: We tested the hypothesis that EC aerosol contains metals derived from various […]
