Meh, in my experience it was junkies who spread it and had it more. Can't say much for the early years because I was only like 7. Juul Vuse and the like are huge ass companies. They want to make money like a good drug peddler. They ain't going to kill their customers. I agree, way more testing needs to happen with this stuff delivery device included. I point to that small period where big news in vaping was exploding vapes. I use a vape to. Not allot. I pretty much gave it all up. But it's the weed industry that stands to lose here. Big weed is getting the protection that big tobacco used to enjoy.
