**"The 51 e-juices sampled make up a very small proportion of all the products sold, and there is variability in the chemical content of specific products as well as how those chemicals are delivered by different devices. The authors therefore acknowledge that it is impossible to extrapolate their results to all the other products on the market. Importantly, this study did not assess levels of diacetyl, 2,3-pentanedione, and acetoin in actual users, much less health effects. So it’s premature to assume that exposure to these chemicals via e-cigarettes causes health problems."

**"As I advised previously, vapers should only use liquids that are certified to be free of buttery flavors that are suspected respiratory toxicants. However, laboratory investigations of e-cigarettes should use validated methods to assure credibility. The results of the Harvard Buttery Flavor Study do not meet this standard." (Rodu) | |||
