LainTrain@lemmy.dbzer0.com 16 hours agoYeah your statement doesn’t contradict mine, as far as we know they are harmless. But we also know really well too, these things have been studied up and down since the 90s and still nothing was really found.
The *blends" thing idk about, the only ingredients out there that go into vape juice are VG, PG, nicotine and flavouring, there aren’t any legal variations on that, this is usually pretty well regulated in the first world.

PG has been pumped through hospitals hvac since the 50s because of its antibacterial abilities. Basically they do it to help curb MSRA infections. We very well know what PG does to us, vaping isn’t much different.

Not since the 50s, in the 50s. And at a much lower concentration than what vaping is.
I've been vaping for about 15 years. Don't get me wrong, vaping is far safer than inhaling tobacco smoke or putting a wad of dip in your mouth. That doesn't make it safe, and I'm unaware of any real studies on the long-term effects of vaping. I am aware of some very badly performed lab studies that were clearly designed to produce results showing how awful it is by operating vape devices in ways that no person ever would or even could. Yes, PG has a mild antiseptic effect. Yes, the flavorings used are "generally regarded as safe" (GRAS) ... for eating.
What I know anecdotally from my own experience:
- Over time, vaping in a closed area leaves a sticky residue on everything. I'm sure my lungs are doing work to eliminate that residue that they wouldn't have to do otherwise, and I don't know the health effects of that.
- The inside of my mouth is constantly dry and feels kind of gross. I'm sure my breath isn't great.
- My teeth are badly stained. I avoid dark juices, as those seem to do it much worse.
All that said, I'm still glad I switched from cigarettes.

Interesting, the study I read, which was like 10 years ago now, when I was vaping, showed that it was still a common thing in hospitals to help curb mrsa infections, and why the air in a hospital usually has a weird feel/taste to it.
That residue is basically from VG/PG buildup with whatever flavor you’re using. I’d be curious if it happened without any flavoring at all. I suspect it wouldn’t build up at all.
