>>526130That's not true, please be careful. Propylene glycol/glycerin (not oil) with nicotine is not the same as vaporizing almost pure hash oil, and neither are the same as vaporizing an irritating extraction like tea tree oil. Vaping dry herb out of a volcano comes out very differently from vaping hot hash oil, which is itself full of liquid smoke and other leftover hydrocarbons from the combustion during the extraction, depends on the method I'm sure. But BHO and PHO fuck people up, even CO2 oil does.
Even if you just inhale PURE HOT AIR it can BURST YOUR ALVEOLI or irritate them, wearing them out and reducing the surface area of your lungs. It also stuns the villi in your lungs, which constantly brush off debris you inhale, for several days.
