Don't worry about your gear bro. For 12 months I pissed in front of my PO once a week, on gear most of the time. I've also pissed for pre-employment while on, passed with flying colors. I think these drug screenings are either a) unreliable or b) drugs clear one's system much faster than they'd like you to think, as I should have been positive for a few different rec drugs on more than one occasion. The myth is that bud takes thirty days to clear your blood or some shit, but I smoked a bowl 12 hours prior on some of these occasions. I guess that's for a different thread tho.
