A Vaping Illness That’s ‘Becoming an Epidemic’

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

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?
