I feel directly inhaling hot ass air in the situation of a vaporizer is....a much different situation compared to air borne elements like a PC or other electronic things off gassing.
I guess a a newer convert to leaving the flames behind.....I just assumed this would be more apparent within this industry because of what you are doing with them to your body.
But, if the evil 'electronic vapors' are present in the room from such sources and are then drawn into the vape and heated....... ZERO difference! No practical difference between the PCB in the vape inches away from the intake and the computer or cell phone a bit further off. The non existent vapors are still let into the vape, heated and sucked into the waiting owner's lungs? Since such vapors don't exist, it really doesn't matter except that guys 'warning us' about this are scaring others. Crying wolf. Speaking authoritatively about threats that aren't real by objective measure. Discouraging potential owners.
Unfortunately this is an emotional issue (go figure) and often becomes fodder for 'my dog (or vape) is better than yours because....' for owners (not so big a deal?). However it's also a popular way for makers to trash each others products (again, par for the course).
I'm very big on defining and avoiding legitimate risks, here and in life in general. When I was working I was Safety Rep for my department (25 or so employees and visitors). Among other sins. I was taught a formal way of dealing with threats (some of which were very severe, we had lots of nasty, even explosive, stuff in the workplace and lots of random (untrained) visitors). Including radiation, electrical exposure, pressurized gasses, toxics of many types and other extra challenges. And my personal favorite, HF (Hydrafloric Acid) which quietly eats through your skin to destroy the bones under it without any sensation to the victim. Truly nasty stuff, much more dangerous than the sort of acids the Brits throw on people they don't like. The base of such things is understanding the nature and extent of the real threat and dealing with it accordingly. That training/attitude has carried over you see? Water can be toxic, as can CO2, in the wrong situations. A few ounces of Ethanol in a squirt bottle is a fire hazard, but nothing like say Hydrogen gas. Give due caution to the first, but watch the latter like your life depended on it......'cuz it does. As do the lives of those around you. Define the risk and mitigate it. But don't waste time and bandwidth on trivial (especially non existent) ones. Stay focused on the real threats.
At least that's my advice, free and worth every penny.
