You're not thinking this through.
Yes it is possible to have an allergy to PG but look at the percentages of what you're vaping. If you move the decimal pont of the MG figure one place to the left it gives you the percentage. 20mg nic salts is 98% diluted. Why do you think DTL tanks only use 3mg juice which is 99.7% diluted? Because if you put any juices in it with higher nic it is unvapable.
I've spent years thinking this through. Anyone can buy 100% pure propylene glycol in 5 litre containers because it's no danger to anyone. I use it all the time when I'm mixing recipes.
I don't know the exact figure but above a certain amount purity you need a license to buy nicotine.
Dtl tanks don't only use 3mg juices, they use whatever concentration of juice a person chooses. It may be the most popular, but plenty of people vape concentrations over 3mg dtl.Yes it is possible to have an allergy to PG but look at the percentages of what you're vaping.

I can buy peanuts anywhere without a licence. Does this mean my friend is imagining his allergy.
Somebody needs to re-read their first post.
