If they are going to make statements about whether vaping is a safer alternative to cigarettes, why didn't they include smokers in the study to see if prediabetes was even more prevalent in that cohort?  And, even if vapors exactly match the results of smokers then it may still be that vaping is safer because given the ingredients it seems much less likely to contribute to cancer.  This is an anti-vaping study that tailored their presentation of the results to fit their desired narrative.  NOONE should be advocating for vaping.  They should only be advocating for vaping as something that still has real risks but is a much safer alternative to cigarettes.
