you will know if you are taking one of those test, usually for positions with the gov or security clearance, they cost more so most companies don't use them. So it will pass every regular test, I used Quickfix
I have always had negative interest in the Dynavap(or any other butane vapes) but something about this lowkey makes me want one, has anyone used this while hiking? (I know its cold as hell right now lol)
