Cannabidiol (CBD)/Tetrahydrocannabinol (THC) Ratio, Urine

This test measures the specific amounts of CBD and THC in your urine to compare the levels of these two cannabis compounds. It helps clarify whether a positive drug test for marijuana was likely caused by using CBD products rather than traditional marijuana. This distinction helps rule out recreational drug use when a person has only consumed CBD. However, this test cannot determine exactly when the substances were used or measure your level of impairment.
