    Around 9 days in mouth swab test, 30+ days in urine test and 90+ days in hair strand test - in some hospital lab tests it can be found in blood up to a few years after use but this would only be done if a person had died for no reason.

    Whether you mix pot with an opioid or not, the THC in the marijuana can be detected in urine and blood for up to 30 days. It's a sticky little compound!
