In a private video conference held in March, Colorado's Marijuana Enforcement Division acknowledged to industry representatives that the volume of chemically converted hemp being illegally sold as marijuana is far greater than the agency has publicly disclosed. The virtual meeting was convened by members of Colorado Leads, a marijuana industry trade group, and an audio recording was reviewed by ProPublica and The Denver Gazette.

Kyle Lambert, the enforcement division's deputy senior director, told participants that the number of hemp-derived products being sold in place of regulated marijuana is "larger than we can quantify." He said regulators feared the prevalence of banned hemp was driving down prices for legal marijuana within the state while facilitating the diversion of high-grade cannabis products into black markets in other states where marijuana remains illegal.

The meeting took place as The Denver Gazette and ProPublica were conducting testing that found signs of hemp in marijuana vapes sold at dispensaries. Regulators also said they had discovered instances where hemp-derived vaping products contained contamination from toxic chemicals used in the conversion process.

Industry participants described the situation during the March briefing, saying the problem had "metastasized" and now posed an "existential threat" to Colorado's legal recreational marijuana market, which launched as the nation's first in 2012 when voters approved Amendment 64.

Dominique Mendiola, senior director of the Marijuana Enforcement Division, said in a statement that Lambert was "speaking frankly to highlight the scale and complexity of the problem." She noted that investigations into suspicious transactions require extensive resources and can take significant time. The agency has "consistently been proactive" in pursuing rules and legislation to address the issue, she said.

What the Left Is Saying

Consumer safety advocates and public health officials who support stricter marijuana regulation argue that the scale of illegal hemp infiltration represents a direct threat to Colorado's regulatory framework. They say consumers purchasing products from licensed dispensaries believe they are buying tested, safe cannabis when some items may contain untested hemp derivatives with potentially harmful contaminants.

Progressive Democrats in the state legislature have called for emergency rulemaking and additional funding for enforcement. State Rep. Yadira Caraveo and other Democratic lawmakers have argued that without stronger testing requirements and enforcement mechanisms, Colorado's legal market risks losing consumer confidence. Advocates note that the abandoned bill would have allowed voters to decide whether to overhaul contaminant testing protocols.

Organizations including the Marijuana Industry Group say the proliferation of illegal hemp products is forcing law-abiding businesses into an unfair competitive position where companies using cheaper, unregulated hemp can undercut prices for licensees following state rules.

What the Right Is Saying

Some Republican lawmakers and free-market advocates question whether Colorado's existing regulatory structure is equipped to address the problem effectively. They point out that despite years of regulation and a seed-to-sale tracking system mandated since 2012, regulators are now acknowledging they cannot quantify the scope of illegal sales.

State Sen. Ray Scott and other Republicans have noted that emergency rulemaking proposals announced two weeks after the March meeting have not yet materialized into action. Critics argue this demonstrates regulatory inertia rather than a genuine commitment to enforcement. They question whether expanding state authority over hemp products would simply create new compliance burdens without solving the underlying problem.

Libertarian-leaning observers suggest that the state's attempt to ban certain hemp conversion processes while allowing hemp production for export creates contradictory incentives that have contributed to the current situation. Industry voices aligned with free-market principles argue that simplifying regulations could address some market distortions driving illegal substitution.

What the Numbers Show

The March meeting audio indicates Lambert told industry participants that suspicious transactions in Colorado's tracking system "would probably explode your minds," suggesting significant discrepancies between recorded sales and expected inventory flows. The specific figures were not disclosed publicly.

Industry lobbyist Jordan Wellington estimated during the meeting that hemp products now represent approximately half of the market, though this figure could not be independently verified. The Denver Gazette and ProPublica investigation found evidence of hemp in tested products but did not establish a comprehensive market share calculation.

Colorado's legal marijuana market generated approximately $1.5 billion in retail sales annually prior to recent price pressures. Regulators have not released data quantifying the volume of suspected illegal hemp sales or their impact on tax revenue collection.

The state operates a seed-to-sale tracking system mandated by Amendment 64, though regulators acknowledged anomalies in the system during the March discussion. Emergency rules announced in late March had not been finalized as of publication.

The Bottom Line

Colorado's acknowledgment that illegal hemp sales exceed public estimates represents a significant challenge to the state's decade-old legal marijuana framework. Regulators face pressure to deliver emergency rules while working with lawmakers who abandoned proposed testing overhauls during this year's legislative session.

The situation raises questions about enforcement capacity and whether existing tracking systems can detect substitution of hemp for regulated cannabis products. Industry representatives warn that continued price competition from illegal hemp could force legitimate businesses to cut corners, potentially undermining the safety assurances Colorado promised consumers when it legalized recreational marijuana.

What happens next will likely depend on whether regulators finalize emergency rules this year and whether legislators in future sessions revisit testing reforms. Consumer groups and licensed operators are watching closely to see if announced crackdowns translate into enforcement actions or remain proposals.
