Depending on how often a user smokes JWH-018 and how much of JWH-018 is smoked, presence of JWH-018 metabolites can be detected up to 72 hour after the initial use. Usually just the presence of the metabolites confirms ingestion.

"There are no cut-off levels for RTL's Synthetic Cannabinoid Test. Toxicology result reporting for JWH-018 and JWH-073 will indicate either 'Detected' or 'Not Detected.' RTL's test will utilize the most sophisticated, sensitive and specific equipment and technology available, LC/MS/MS (liquid chromatography/mass spectrometry/mass spectrometry) to confirm JWH-018 and JWH-073 metabolites."

Redwood Toxicology Laboratory, one of the two labs that can detect JWH in urine, announced in August 2010 that they have develoved and are offering a drug test that can detect JWH metabloitles:

Redwoods website states, "RTL now offers lab-based testing for the detection of JWH-018 and JWH-073 metabolites in urine. JWH-018 and JWH-073 are the primary synthetic cannabinoid receptor agonists responsible for the euphoric and psychoactive effects that imitate marijuana and are among the numerous compounds found in "herbal" incense or smoke blends. Conventional drug test panels will not detect the broad range of synthetic cannabinoids. They pass undetected in standard urine testing for such drugs as cocaine, marijuana, heroin and amphetamines. RTL's Synthetic Cannabinoid Test can be ordered with your standard panel to ensure JWH-018 and JWH-073 are detected."
