With a hair follicle test they usually go back about 6 months, and I think it will show up that far back. As for a urine test, it really depends. THC is fat soluble, so it stays in your system a long time--ie it's stored in fat. I've heard of people losing significant amounts of weight and having its metabolites show up in their urine years after they last smoked pot. Barring that, I would guess something like a month just to be on the safe side. Some people argue that trace amounts show up just from being in the same room with people who are smoking, but I've also heard so-called "experts" (whether they are or not, who knows) say that's a fallacy, and that being in a smoke-filled room will not cause anything to show up in a urinalysis at all. So whether or not you take a test sooner and rely on that argument to explain away any inconclusive results would be your call.Health Question & Answer
