// Definition
The systemic discrepancy between THC percentages printed on cannabis product labels and actual cannabinoid content, driven by selective sample testing, lab shopping, and the practice of mixing trim into pre-rolls while using top-bud test results on the label.
// From the Episode
Jeff Rosson found manufactured products (gummies) from dispensaries are generally accurate, but flower and especially pre-rolls are almost always lower than labeled. In Massachusetts, a standard boardroom practice is mixing 50/50 bud-to-trim ratios in pre-rolls while labeling them with the top-bud test result, creating products labeled at 30% THC that actually test at 14%. Typical lab-based inflation adds about 20% to true values. He compared cannabis labeling to consumer protection standards for food products like Triscuits.
