    Using it to quit smoking is a good idea

    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.

      1. 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

      2. That’s an invitro study which is basically worthless.

      3. That’s a valid point about Chinese eliquid, which is part of why disposables aren’t a good option.

        That is wrong.

        That’s an invitro study which is basically worthless.

        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.

          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
