If I have it right, antifreeze is Ethelyne (sp?) glycol.
Not sure how different Propelene glycol is.
Hell, sodium and chlorine will both kill you, but together they’re table salt.
At least you’re not smoking, congrats!
I quit a heavy, 35-year smoking habit in April by switching to vaping. I use a KGO and high-end juice.
This is a bit old, but has some good info. This forum also has a ton of good info,
Propylene glycol is a common additive in food, and also a propellant in asthma inhalers since the 1950s, so it can’t be *that *bad for your lungs. Better than smoking, certainly. Also as Joey P says, many juice vendors will mix juice with 100 percent vegetable glycerine. But you lose the throat hit with 100 percent VG.
Yeah, common antifreeze is ethylene glycol, and that’s the stuff that’ll kill you. Propylene glycol, on the other hand is used for all kind of human consumption, internal and external. I believe PG is also sometimes used as safe antifreeze in applications where some piece of industrial machinery might spring a leak and get into food.
