This groundbreaking research is shedding light on the accuracy of product labeling in Colorado.

In Colorado, all cannabis products must carry state-mandated labels detailing the potency of specific cannabinoids and confirming testing for potential contaminants. The study’s primary objective is to provide independent verification of these labels by comparing them with separate laboratory testing results. State regulations require that the actual content of five main cannabinoids must be within 15% of what’s stated on the label.

The research team represents an important collaboration between MedPharm Holdings, with its rare state-level research and development licenses and specialized testing equipment and UC Boulder whos researchers provide unbiased academic oversight and data interpretation focused on public health implications.

Preliminary findings from approximately 100 concentrate products are encouraging. The research shows that almost all tested concentrate products accurately match their label claims – a significant achievement given these products’ high potency levels. Any discrepancy in either direction could have substantial implications for consumers. Testing will continue for products across the full range of our legal market, including flower, edibles, topicals, and tinctures.

The study team is preparing to present their initial findings at scientific conferences this summer and share results with state legislators. However, they emphasize that the research is still ongoing, with final conclusions and peer-reviewed publications expected in about a year.

This research highlights Colorado’s commitment to consumer safety and transparency in its cannabis industry. As one of the first states to legalize recreational cannabis, Colorado’s robust labeling requirements and verification processes could serve as a model for other states developing their own cannabis regulations.

The accuracy demonstrated in the preliminary findings suggests that Colorado’s cannabis industry has successfully implemented reliable testing and labeling practices, particularly for concentrate products. This accuracy is crucial for both consumer safety and industry credibility as the cannabis market continues to expand nationwide.
