How long can second-hand smoke (marijuana) stay in the body?
There may be traces in your system, but I doubt anything significant. The smell might be potent, but the concentration of marijuana smoke in the air was very small. There is a certain level of the THC byproduct that must be present in your system for them to reasonably determine that you are a user of the drug. If you dont smoke weed at all then your body should metabolize it fairly quickly. If you are still weary, I would suggest drinking a lot of water the day before the test. I also heard that taking aspirin a few hours before the test can mess up the urine test so it will come back negative. Might wanna do some research on that one, but anyways… my guess is that you will be fine regardless! Kenny A.
