A Vaping Illness That’s ‘Becoming an Epidemic’

We simply don't know how safe vaping is.

Why do you say this so categorically?

"...[R]ats were nose-only exposed to filtered air, nebulized vehicle (saline), or three concentrations of PG/VG mixtures, with and without nicotine...Compared with vehicle exposure, the PG/VG aerosols showed only very limited biological effects with no signs of toxicity."

Propylene glycol has been used as a carrier for pulmonary inhalers as well as in food and cosmetics for decades.

While there is evidence showing the short term safety of inhalation, there is no evidence as to the long term effects of consistent repeated exposure.

Propylene glycol was deemed safe for oral consumption, not inhalation. I have not seen any sources of information indicating its use in pulmonary inhalers, do you have some sources you can link?
