Yes, generally the health community has been talking about a minimum of 20 years to get 'long term' data on the effects of vaping Another problem they're dealing with is that we talk about vaping being one thing - in reality there are hundreds of companies with their own solutions. Of course there are some similarities in products and in the last few years Juul has come to dominate the US market, but other products (both the devices and the liquids) are of murky origin and quality. I was recently reading a study of a scientist looking into some devices and they found some contaminants that they didn't expect to be present at all that had no reason being there other than a use of cheap/incorrect/mistaken materials Source: various, I've been researching tobacco control broadly for the last ~5 months as part of a project, if anyone is interested I can pull together some of the more interesting reports I've read
