Re: Hate to be pragmatic but
Vaping is a relatively new thing
But heating a mixture of propylene glycol and glycerin isn't. It dates back many decades. Stage smoke, military demonstrations, delivery of drugs for asthma, all rely on the same technology. If it's relatively untested as is so frequently claimed, why the fuck are doctors and nurses allowed to treat asthmatics with the technology? If it's unsafe for e-cig users, it's unsafe for asthmatics.
