Even if the vape juices were manufactured with only ACS grade chemicals free of impurities there isn't much meaningful data on the health impact of 'vaping' said chemicals. Vaping data won't be meaningful until there's a standardized vaping device made of non-reactive components (stainless steel, glass, PTFE, etc.) to use in clinical trials.
