Can you be allergic to PG (propylene glycol)?
Yes, it's rare, but it happens. If you start coughing like you swallowed a hedgehog or if your throat turns bright red, you might be PG intolerant. Don't panic—there are e-liquids made with Vegetol to save your lungs and your night.
PG allergy manifests as severe irritation of the mucous membranes or skin rashes. Vegetol is a natural alternative obtained through the fermentation of cereal sugar. It provides a physiological hit similar to PG without the irritation for sensitive users.
