Media worldwide accordingly reported this new health hazard of e-cigarettes.
A new study published online today in the scientific journal Addiction took a closer look at the NEJM findings in the context of real-world conditions. It concluded that 3rd generation e-cigarettes can indeed produce high levels of aldehydes, but only under extreme conditions which human smokers can be expected to avoid because of the immediate unpleasant sensory effects.
