I understand that you want to give them the benefit of the doubt, but in this case you are are wrong. During this "crisis" there were Congressional hearings (which I watched two of live on CSPAN) where a CDC representative did blame the issue on nicotine
vaping, and even went on to say that
vaping PG and VG are not safe but that
vaping approved THC carts was safe (despite the fact those also contain the same PG and VG) and also added that a nic juice flavor ban would NOT impact adults. Sorry, but you claiming they are only going to state things they can prove is the opposite of what I have seen from them.
