Colorado State Audit Finds Safety Gaps in Marijuana Testing Rules

What the audit reportedly found

A Colorado state audit concluded that the state's marijuana product testing rules contain safety gaps, according to Marijuana Moment's Oct. 20, 2026 report.

CannIntel hadn't reviewed the full audit text at publication. The specific findings, recommendations and agency responses aren't confirmed here. We won't characterize them beyond the reported headline conclusion.

That limit matters. A "gap" can mean many things.

Rule text versus enforcement

On a strict reading, a gap in testing rules is a drafting problem, which is distinct from a lab misconduct or enforcement problem.

Colorado regulates marijuana under Title 44, Article 10 of the Colorado Revised Statutes, with the Marijuana Enforcement Division inside the Department of Revenue writing and enforcing the implementing rules. If the audit targets the rules themselves, the fix runs through rulemaking. If it targets oversight, the fix runs through staffing and inspections.

Licensees face very different obligations under each outcome. Rule changes can arrive with new testing panels, new limits or new sampling requirements. Operators then have to budget for them.

What operators should check now

Cultivators, manufacturers and retailers should audit their own testing workflows before any rule change forces the issue.

A practical checklist, pending the audit's details:

• Confirm how batch sampling is documented and who signs off.
• Review which contaminant and potency panels your contract labs run, including pesticides and THCA reporting.
• Map your recall and failed-batch procedures against current MED rules.

The 280E layer

Testing costs sit at the intersection of product safety and IRC §280E tax treatment, so any change in testing requirements has a tax footprint.

Section 280E bars deductions for businesses trafficking in Schedule I or II substances, but cost of goods sold remains available under IRC §471. Whether a given testing expense lands in COGS is a fact-specific question for each operator's tax counsel.

Stricter testing could raise per-batch costs, and failed batches could mean destroyed inventory. Both hit margins 280E already compresses. Colorado operators shouldn't wait for a rule to ask their accountants how those costs are classified.

What to watch next

The next markers are the audit's recommendations, the MED's formal response and any rulemaking notice that follows.

The signal to watch: whether the Department of Revenue accepts the audit's recommendations and posts proposed rule language, because that notice starts the compliance clock for every licensee in Colorado.
