Abstract
To determine whether ingestion of hemp seed tea could result in positive urine drug screens for cannabinoids, volunteers were recruited to donate urine after consuming hemp seed or placebo tea. Among the 22 participants, 10 ingested 12 ounces of hemp seed tea, 10 ingested 24 ounces, and 2 ingested 12 ounces of placebo tea. Urine cannabinoid specimens were obtained at baseline and at 4, 8, and 24 hours after ingestion. A total of 10 specimens had trace quantities of cannabinoids detected in 7 subjects on gas chromatography/mass spectrometry testing, all below the Department of Transportation cutoff level of 15 ng/mL. These results demonstrate that under the conditions of this study, hemp seed tea consumption can result in detectable urine cannabinoids but would not trigger a positive EMIT or gas chromatography/mass spectrometry urine drug test for cannabinoids.
