Study Finds Major Inaccuracies in THC Labeling of Cannabis Edibles in Mississippi

Researchers from the University of Mississippi Medical Center analyzed 12 edible products purchased from dispensaries and convenience stores in Jackson. Using gas chromatography-mass spectrometry, they compared the advertised contents of Δ8-THC and Δ9-THC with the actual measured amounts. The findings showed striking discrepancies. Some products contained as much as 5,491 milligrams more THC than advertised, while others had hundreds of milligrams less. In three edibles from the same brand, the difference between advertised and tested Δ8-THC content was 1,542 mg, 719 mg, and 5,491 mg. None of the products contained detectable cannabidiol, despite many consumers expecting balanced formulations.

The study warns that such inconsistencies reflect a lack of standardization and quality control in the cannabis edible market. Researchers noted that inaccurate labeling could be especially dangerous in cases of unintentional pediatric ingestion, where even small miscalculations can lead to serious outcomes.

The authors concluded that stricter regulations and standardized testing are urgently needed to protect consumers and ensure that product labels accurately reflect what’s inside.
