The same way people with peanut butter allergies do. It doesn't affect them at all.
BUt if they are around peanut butter, or injest it, they go into anaphalactic shock and for that reason, carry an epi pen to save their lives.
I am rather startled at the total lack of understanding of histological responses to ingredients ...... by being defensive about vaping it's almost like some of you have tossed science to the curb.
Look: People's responses to things are real. they may or may not be related to vaping. But they are real and deserve respect and attention and certainly a solution.
NOT ONE PERSON HERE can debate that someone "could be" highly allergic to vaporized PG. Unless you are a board certified immunologist or allergist.
I've seen allergies to the most simple things. Even "organic stuff'. I jsut got complete testing and of all things, am highly allergic to lavender essential oil. As well as tea tree. Not stuff you wuld think.
Allergies to mint are very common, who would think? So you are blowing peppermint vapor into the air around someone with a high level mint allergy? Yes, it makes them sick.
back in 2012 when I started here I vaped something iwth that cinnamoncide cinnamon whatever compound and my lips blistered, my tongue blistered, and of course, i was "quite concerned" about my lungs after that incident. Yes, things are very specific to individual biological responses. Just because it hasn't happened to you, or to 95% of you, doens't mean it cann't happen.
