Ah mate, you never want to be honest with those types.
I missed out on 2 lucrative jobs at the beginning of this year because I wouldn’t have been able to pass a hair follicle drug test so I’ve been off it for about 6 months now I guess, lost track after the 3 months required for that.
I’m actually now doing better than ever financially (which isn’t saying a whole lot either) without the need to pass such a test, but I’m still not smoking just in case. Probably not gonna smoke again until I’m doing exceptionally splendid.
