Imagine you’re at a potluck, and someone brought a mystery casserole. That’s your vape juice. It’s a mix of propylene glycol (PG), vegetable glycerin (VG), nicotine, and flavorings. Each one of those ingredients is like a party guest who might secretly hate you.
PG is the usual suspect. It’s the stuff that carries flavor and gives you that satisfying throat hit. For some people, PG is like that friend who shows up uninvited, eats your snacks, and leaves a mess. Your immune system might see PG and scream, “INTRUDER!”
Then you have flavorings. That blueberry cheesecake taste? It might be full of chemical compounds that your nose and lungs decide to fight. And nicotine itself can be a jerk—it dries out your skin and tightens your blood vessels, mimicking an allergic response even if you’re not truly allergic.
