Can you fail a drug test by smelling marijuana in the same room as you are?

Hi,
Second-hand marijuana smoke can leave traces of the chemical tetrahydrocannabinol (THC) in your urine for a day or so after breathing the smoke. Usually, the amount is not enough to make you test positive, but it is possible, especially if you have chronic exposure.
