My understanding is the heating the propylene glycol and glycerol in e-liquids creates compounds that release toxic chemicals that are harmful to you with and without the additions of nicotine or THC source. So in short still bad. Short term can cause inflammation, lung and throat irritation, I’m sure there’s more data on long term but cbf finding it.

THC additions have been shown to create a “sticky substance” in your lungs which can lead to further lung injury source. EDIT: THC when paired with vitamin E acetate as thickening solution not THC on its own

Nicotine additions bring in all the side effects of having nicotine in your system. Including an increase in blood pressure, heart rate, flow of blood to the heart and a narrowing of the arteries. Plus a general risk of addiction leading to more vaping and the higher chance of starting smoking.

ELI5 smoking the vapour is as bad and will result in damage to the lungs and throat, but no side effects or issues that come with the addition of nicotine or THC.

Your link and claim about THC is totally wrong. The problem was with people adding vitamin E acetate to the liquids. This is a problem of manufacturing of liquids that doesn't seem to appear much anymore and has nothing to do with THC itself.

Avoid home made liquids like plague. And avoid vaping if you can, continuous irritation of anything in your body is always linked to bad outcome and we don't have enough data on long term use of vaping yet to rule it out in that case.

Flavors can also be extremely bad and these are even less studied and change all the time. Look at popcorn lung for example https://www.lung.org/blog/popcorn-lung-risk-ecigs

That's one compound that makes damages pretty fast for example (and was well known, so people that flavored ecig liquids with that are criminals)

Their first claim is wrong as well. There is no evidence showing that vg and pg release toxic chemical when heated. The studies saying otherwise are falsifying results by subjecting the device to extreme scenarios in which no one would be inhaling

Interesting. This I didn't know about. Do you have studies that studied the liquids in "normal conditions"?
