Study: E-Cigarette Use Reduces Carbon Monoxide, Acrolein Exposure Even For Occasional Smokers

By Dr Deepu

Reuters Health (9/10, Rapaport) reports on a study that found that smokers who switched to exclusive use of e-cigarettes were 80% less exposed to carbon monoxide and acrolein after four weeks while those who vaped and smoked reduced their exposures by 52% and 60% respectively. The authors noted that the most significant finding was that those who used both cigarettes and e-cigarettes showed significantly lower acrolein levels despite the presence of vegetable glycerin in the e-liquid, which could have increased exposure.
