Is inhaling glycerin bad for you?

Inhaling glycerin, particularly in the form of e-cigarettes or vaping products, can pose health risks. While glycerin itself is generally recognized as safe for ingestion, its effects when inhaled are not well-studied. Potential concerns include respiratory irritation and the formation of harmful byproducts when heated. It's advisable to approach inhaling any substance, including glycerin, with caution and to be aware of potential health implications.
