More on Hidden Formaldehyde in E-Cigarette Aerosols

New England Journal of Medicine 372(16):1575 (2015) PMID 25875273

To the Editor: The data presented by Jensen et al. (Jan. 22 issue)1 in their recent letter to the Editor do not support their conclusion that e-cigarette use presents a likely risk of excessive exposure to formaldehyde. The 5-V puff topography used by Jensen et al. appears to have overheated the coil, resulting in excessive breakdown of propylene glycol to formaldehyde. This phenomenon is readily detected by the consumer by virtue of an exceedingly unpleasant burning taste, commonly referred to as a “dry puff.” It has been described in detail in the literature.2,3 The consumer can address this issue . . .
