THC Metabolites Detected in Urine Following Full-Spectrum CBD Use
The November 4, 2020 issue of JAMA Psychiatry published results from a recent study examining whether the use of full-spectrum CBD from legal hemp (< 0.30% Δ9-THC) would lead to positive urine test results for THC metabolites. It has been often assumed that hemp-derived cannabidiol products will test negative for urinary THC. However, the study showed that half of subjects tested positive for carboxy-THC, an inactive metabolite of Δ9-THC, after four weeks of daily use. Samples were initially screened through urine drug assays. Positive screens were confirmed through gas chromatography-mass spectroscopy. The results suggest that individuals consistently using full-spectrum, hemp-derived […]
