You all do know that Propylene Glycol is Antifreeze
up till the mid 1990’s the blue stuff was ethylene glycol antifreeze.
After that they changed to the Green or a hybrid of the two for mid aged cars antifreeze. then they came out with various colors to denote various additives for various different engine and cooling system requirements.
IIRC, anything called Antifreeze has a poisons label and “Do Not inject, call Emergency Hotline asap” clearly marked on each container.
Slide on Antifreeze - Vape Nicotine liquids cut with PG (Propylene Glycol) harsh biting type of throat hit (dont ask I read it) were the maid causes of breathing issues with those who mixed their own “flavoured” liquids.
Using Vegetable Glycerine as the cutting fluid did nothing to lungs and throat system, so the only thing that harms the person is the chemicals they use to flavour.
How do I know, 20 plus years of vaping, Only used VG, no flavors.
Had to do a lung proficiency test and have CAT and MRI scans for an unrelated issue and also insurances.
Doctor came back and said did I smoke as I wrote it down, I said yes, Only VG, for some 20 years.
He replied I had the lungs of a healthy 20 year old. Full pass and I was in No way harming myself as VG is in most food stuffs and is absorbed within the body with zero effects.
I am Not 20.

Interesting on your PG experience (see my post from last March), but you’re confusing PG with PEG and ‘antifreeze’.
Totally different animals, all 3.
Have a good night.
