Long term exposure to alcohol vapor can lead to nerve damage, lung damage, and death. I would definitely caution against long term or frequent vaping of alcohol. I don't care which vendors are using alcohol in their liquid, it isn't a good idea.
Last I read VG and PG are chemically alcohols, so y'all might wanna be more specific.

pure alcohols... or even a 70% iso, don't leave a residue. You just have to either let them air-out or rinse them thoroughly. I'd be interested in an actual study of inhalation of PGA in very low concentrations though.
I use alcohol in a few recipes ~1%. Never noticed any ill-effects. Is possible you were experiencing something else, no? Maybe some other ingredient or something else with their process.
The difference between essential oil therapy and vaping is pretty big. The oil is usually heated to just over 100 degrees Fahrenheit using a very small flame or hot rocks. It is then allowed to diffuse in the atmosphere. When vaping the oil can be heated to over 100 degrees celsius and is then inhaled directly into the mouth and lungs. You are getting much more of the chemical in the atmosphere (your mouth) and then into your respiratory pathways.
I'm not saying it is bad. I am saying that the two systems of delivery are so different that one should not be used to judge the other.
Yes, snorting xanthan gum in water is also bad for you. It's just pretty much never going to happen. It's easy to inhale dry dust a little at a time, not so much the liquid. And it is still completely different from vaping.I found the msds for the liquid, and it definitely cautioned against inhalation And yes, I'd stay away from inhaling the powder form too =)
Essential oils are made up of the same molecules used to build flavors. This does mean that they can come with problematic allergens, but so can flavors -coughcoumarincough- and it's certainly not a wild new scary thing. Some of your flavors almost certainly have essential oils in them. If they don't, they absolutely have molecules which make up the greater part of one or more essential oils.The difference between essential oil therapy and vaping is pretty big.

Coumarin is another one that often makes its way in flavorings yet should be avoided.
