OK. Point received, but that was written 2 years ago and the industry has changed. If DOW OPTIUM is the only possible source to vape then why doesn't every vendor carry it?
Yes I know the age of the post, but the key words are "It is possible", does not mean it is, or is not, it is just something to think about is all I was pointing out. I wish there was something besides just USP for a grade. I looked at a gallon jug at Tractor Supply, Listed "Propylene Glycol, U.S.P.", but also said "Not for human use". So I wonder if that is safe to vape? Makes you think.
