Everything is poison at the right dosage.
I've read they use it as a suspension for children's cough syrup...so doubt it's that bad.

They also use it in nebulizer-type inhalers, for children and others.

If someone's skeptical, tell them to Google "nebulizer" when they're doing their research on PG or other purportedly nasty chemicals. They'll find that lots of medicines are delivered by vaporizing them in PG.
