I’m pretty sure most people get more nasty stuff into their bodies by eating a bowl or at least a box of cereals than you get into your system in a lifetime by vaping flavors that contain Diketones.
In my mind the hysteria around this is getting overboard and when a few demand that the flavor companies make all their flavors free of Diketones i think it starts to get on the ridiculous side of things.
Instead of demanding that all flavors containing Diketones be gone you could demand that the flavor companies develop Diketone free flavors for you and leave the originals alone for those that appreciate the flavor Diketones add to a mix.
I feel that a small group of people shouldn’t decide for the DIY as a whole. We got enough of that kind of dictatorship in the world already.
