lol. The same delivery system of propylene glycol vapor is what is used to deliver the medicine in asthma inhalers.
They already did think of it in a sense. But you are right in principle.
Not really.
The ecig is battery operated and intelligently activates an atomizer when suction is detected. An inhaler is just a pressurized canister that opens briefly when a person pulls a manual trigger.
I’d say patent-wise they are clearly different animals altogether.
