Drug DUI (DUID) Urine Test in Pennsylvania

Urine tests are not accurate or reliable ways of testing for drug impairment. The urine tests typically determine only the presence of certain metabolites that are found in controlled substances, but cannot actually determine the drugs themselves.

For example, a urine test will not give a clear reading of whether the driver was under the influence of marijuana or cannabis at the time the driving occurred, even when certain marijuana metabolites are present in the urine sample.

Pennsylvania recently enacted a statute for Driving Under the Influence Drugs (DUID), which prohibits a person from driving a vehicle while under the influence of drugs, including marijuana and cannabis metabolites. Under the per se version of this law for DUID, a driver with more than 5 mg/ml of THC is presumed to be guilty of DUID under Pennsylvania law.
