Reading data in the right context
Unfortunately, pointed out Godshall, using “ever” and “current” usage data, especially when the latter may include a large number of experimenters, social e-cigarette users and also THC vapers “is pretty much useless for understanding actual usage patterns of vapers and cigarette smokers.”
In order for current data to be deciphered properly, it should be compared to similarly obtained data from previous years. Additionally, it is also critically important to obtain and compare daily vaping and cigarette smoking figures and try to extract patterns in order to understand such behaviours.
