I would add that the average mech user is far more concerned and careful about battery use than the average regulated mod user. Especially with internal batteries. Ever notice that that is the largest group of incidents? Just like with cell phones, which provide fireworks far more often than any vape devices.
Also, charging batteries in the mod, especially with multiple battery mods, is, at best, cooking your batteries. At worst, it's a definite fire hazard.
I actually talked about this to my neurologist yesterday. I showed him my pocket setup, and gave him details like nicotine concentration and amount of daily use. The first thing he told me was that the lung doctors he talked to (he's an assistant chief of staff at the hospital he's associated with) all agreed that they would rather deal with any consequences from vaping rather thaan the intense destruction of smoking. They also told him, each one, that they had never actually seen a lung problem due to vaping.
He's also completed a residency in psychiatry, so he knows how difficult it is for someone with Parkinson's to quit nicotine. It provides a small, very temporary relief of some symptoms, and semi-consciously makes you feel like you're doing something about it. He told me that it would not be a responsible thing for him to do to actually recommend that someone take up vaping. But he's in favor of it if you did it of your own volition. He told me that he also believes that it's my best bet to keep me off tobacco (and flames) long term.
He told me that if it comes to that, and writing a prescription was an option, that he would be glad to prescribe me liquid nicotine.
