White graphite (hBN) a worthwhile chain lube?
Well, white graphite (or hexagonal boron nitride for all the big brainers) is fine to use as a lubricant, but like @mattnz said, don't snort it (mattnz is big brain). Regular graphite can be corrosive do certain metals with moisture, but as long as its white graphite, I don't see any issues that would pop up.
