This paper presents some interesting data, but the language it uses is misleading. The word ‘initiation’ implies a start of regular use, but the data concern mostly a single instance when people tried an e-cigarette. Among non-smokers, progression to regular vaping is extremely rare. Trying vaping once or twice and never going back to it does not initiate anything. (Among smokers, a switch to vaping is a good thing).

Describing e-cigarette use as ‘e-cigarettes smoking’ is another misleading sound-bite. Vaping poses only a small fraction of risks of smoking.

Finally, preventing e-cigarette use is not ‘tobacco use prevention’. Vaping does not include use of tobacco. If the authors mean by this phrase that experimentation with e-cigarettes inevitably leads to smoking, there is no sign of that. Smoking prevalence in youth is declining at an unprecedented rate.
