Which medications? Ventolin does not use propylene glycol: https://www.drugs.com/pro/ventolin.html https://www.drugs.com/pro/ventolin.html Airomir did not. Maxair? Nope: https://www.drugs.com/pro/maxair-autohaler.html https://www.drugs.com/pro/maxair-autohaler.html Even pro-vape sites recognize that this is BS. > There is one study looking at the potential to use PG as a carrier for an inhaled medicine (https://www.ncbi.nlm.nih.gov/pubmed/18158714 https://www.ncbi.nlm.nih.gov/pubmed/18158714) and another which mentions that PG or ethanol may be used as a cosolvent (https://www.ncbi.nlm.nih.gov/pubmed/12425745 https://www.ncbi.nlm.nih.gov/pubmed/12425745) in nebulizers, but no evidence presented of an asthma inhaler or nebulizer that is actually used today containing PG. There's also a huge difference between 3-4 puffs a day of a smaller amount, than chronic hundreds of puffs a day with vapes.
