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.
- shkkmo 7y agoWhile 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?
