Not really. You are just exchanging one addictive habit for another. Tobacco companies have been selling vapes as safe alternatives to smoking driven by social media bots and MD shills, but it's a big fucking lie.
Heating glycerol to make vapor breaks glycerol, a safe compound into DHA dihydroacetone, which causes DNA damage which can trigger cancer in lung.
But that's just DHA. We have no idea and have no testing or regulation of what goes into vapes coming out of Chinese chemical plants. No one is looking at this.
Vapes don't typically get hot enough to break glycerin down into DHA. The normal temperature range is 400-450F while glycerin breaks down at 536F
That's an invitro study which is basically worthless.
That's a valid point about Chinese eliquid, which is part of why disposables aren't a good option.
That is wrong.
It's in cell models, not in vitro.
Here's a mouse study.
We'll just wait for the human data to eventually show up, but the studies running on this were killed by Trump when he killed the NIH last year. No way inhaling huge quantities of DHA isn't dangerous. This is a major concern in sunblock cremes and that's not even deep ingestion into lungs.
Bro, they were firing old school clearomizers with a starting wattage that's at the top of what's recommended. You can tell by the conversation graphs because EC3 is a more modern tank and it's an order of magnitude lower.
There's a reason why clearomizers didn't stay around long. They designed this study to produce DHA. You can tell because there was no change in EC3 across the temperatures, yet they scaled their graph to make it look comparable to the clearomizers. And the levels in EC3 were so low that it could have easily been machine error given the way they had to measure it.
The amount EC3 produced is 50x lower than the lowest amount the mice were exposed to.
If you use a temperature controlled mod, this is all a non-issue.
Remind me in 10 years
I've been vaping for 15 years now. Lungs are perfectly healthy. But I make my own unflavored e-liquid with nicotine purchased from a pharmaceutical producer so I know exactly what's in it
Most smokers are fine with 15 years. Have you have a pulmonary work up or is this just feels?
I've had a pulmonary workup recently, yes.
