Ok, I've seen this crop up multiple times in short order on this sub and I felt the need to re-share this here since so many seem to be buying the propaganda of a company trying to appear like they are taking the high road instead of just getting wrecked by their competition.
The study shows you some rather scary pictures of silica dust and talks about the dangers and health risks of inhaling it, citing Silicosis and death.
The part they leave out? Historically people who have come down with these sorts of health issues worked in industrial settings cutting ceramic and being exposed to high levels of silica dust without having any sort of breathing mask. (heck at the end of the article they even cite a wiki article that lines out this health problem comes from industrial settings)
Independent testing of ceramic coils in e-cigs have come back with zero signs of any silica dust in lab settings under a microscope.
(one example: https://www.docdroid.net/hftSRNe/1215-592.pdf.html
there are others out there as well, this one is just easier to find without tracking down company reps and asking for testing results)
Conclusions: Is ceramic 100% safe? We're not explicitly sure, just like most things with vaping, but science has yet to show the amount of ceramic even the most cloud chasing ent would actually be exposed to would be problematic nor evidence that any ceramic option on the market is actually putting off any
silica dust at all.
If you don't want to use ceramic because of the possibility of problems; that's absolutely your choice and there's nothing wrong with that.
Just be mindful there has yet to be any
evidence that any ceramic vape device is actually problematic; just parallels to other potential health problems that come from much higher rates of exposure.
