## Colorado Marijuana Lab Testing Scandal: Hemp Contamination Undermines Legal Market Safety Promises
An investigation by the Denver Gazette in partnership with ProPublica reveals that Colorado's regulated recreational marijuana market, the first in the nation, is being undermined by the infiltration of cheaper hemp derivatives, jeopardizing the state's promise of a safer, regulated environment. For years, hemp, a close cousin of marijuana, has seeped into the Colorado marijuana market. While Colorado allows the use of hemp-derived THC, the state's testing protocols have failed to distinguish between marijuana-derived and hemp-derived THC. This loophole has allowed producers to use cheaper, potentially less-regulated hemp to create intoxicating products that are then sold as regulated marijuana, bypassing the stringent safety and testing standards promised to voters. The investigation has prompted Colorado marijuana regulators to consider major changes to how labs test for contaminants, a direct response to the reporting that exposed the systemic flaw in the state's regulatory framework.
