You may very well evade the suspicion of your future employer, but you can never fool the Lord. You will receive your punishment in hell for your wretched herbal hippie sorcery
I was urine/bloodtested once, in a medical non work related context, the drugscreen only managed to identify 1 of the 4 common narcotic substances I consumed the night before. All with 72+ hours minimum of biological half-life. With all of your efforts any concentration (if available) is probably going to be so miniscule you could blame it on secondhand inhalation and get a new test. Glad drugtesting is not common practice here, although I don't touch drugs anymore.
I think you will be fine, child of satan.
