- EdwardDiego 7y ago> Propylene glycol has been used in asthma inhalers Do you have evidence for that claim? Because as an asthmatic, I've never encountered an inhaler that contained PG. Apparently it can be used in nebulisers, but unlike inhalers and e-cigs, a nebuliser isn't being used every day.
