Is vape juice safe?

Some of these additives found in e-liquid are dangerous — even deadly. For example, vitamin E acetate has been indicated in EVALI, which stands for e-cigarette or vaping product use associated lung injury. This is a potentially fatal syndrome associated with vaping, and it was on the rise in 2019. Vitamin E acetate is OK to eat, but dangerous to inhale.

“There’s no doubt about it,” Blaha says. “Some of the chest X-rays of patients with EVALI show signs of oily chemical irritation of the lungs.

“So when it comes to inhaling best vape juice juice, we don’t know what’s ‘safe.’ You may be able to eat something safely, but if you inhale it, there may be a harmful effect.”

Blaha says there’s limited evidence that vape juice flavors themselves are dangerous to individual users. But there are unknowns — research suggests that flavors, when combined with other 100ml vape juice juice ingredients and heated, can create new compounds that may be harmful.

Inhaling harmful substances can affect more than just the lungs. Some vaping enthusiasts describe a phenomenon called vaper’s tongue, which causes a sudden full or partial loss of the ability to taste.
