Yes, it is possible to get a false positive. There are certain medications that can cause you to test positive for THC, mainly antiretroviral medication, even though there is no actual THC present in your body. It is also possible for a urine drug screen to be faulty and give a false positive, however this is unlikely. They will then re-test the same urine with a new test to determine if this was indeed the cause of a false positive.
