Colorado health regulators issued two separate warnings this month after cannabis products sold across the Denver area failed state safety testing — one for moldy flower, the other for vape cartridges with excessive butane. The products came from two different companies, but both ended up on shelves at multiple metro dispensaries before regulators caught the problem.
The Colorado Department of Public Health and Environment and the Department of Revenue Marijuana Enforcement Division issued a joint health and safety advisory on September 11 for marijuana flower sold under the brand Locol Love, made by Navajo Management LLC, according to Westword. Testing found yeast and mold levels above the limits set in Colorado Marijuana Rule 4-215, the state regulation that caps Total Yeast and Mold counts at 10,000 Colony Forming Units per gram and holds cannabis to zero tolerance for E. coli and Salmonella, per the Code of Colorado Regulations. The affected batches, numbered 20260317gv2d and 20260203km4d, were sold at 10 dispensaries across Colorado between April 10 and August 21, including Natures Medicine South Denver at 9206 E. Hampden Ave., Elite Cannabis at 1410 S. Santa Fe Dr., and Social Cannabis Dispensary at 1119 Syracuse St.
Five days later, on September 15, regulators released a second advisory covering vape devices sold under the Stash House CO brand, made by CC Brands LLC. Those vapes — specifically batch 1576, sold as Bluecifer Berry Kush Indica 2g cartridges — tested with butane levels exceeding the limits established in the same state rule. The vapes were sold at 43 stores statewide between August 13 and September 3, with 12 of those locations in the Denver area, including Golden Meds at 4620 N. Peoria St., Native Roots at 7870 W. Quincy Ave., and Social Cannabis Dispensary, which also carried the tainted flower batch.
State Won't Say Where Contamination Started
Colorado regulators said the advisory itself does not determine where the contamination originated in either product's supply chain. Both notices carry the same guidance: anyone holding either product should destroy it or return it to the store of purchase for proper disposal, and anyone who experiences adverse health effects after using either item should seek medical attention right away.
The state also directs consumers who get sick to file a report with the Colorado Marijuana Enforcement Division using its official reporting form. That reporting mechanism has taken on new significance this month — the division issued Industry Bulletin 26:09 on September 11, just a day after the Locol Love advisory, laying out expanded implementation guidelines for residual solvents testing across licensed businesses statewide.
A Familiar Name for CC Brands
This isn't CC Brands' first brush with state enforcement. The company, doing business as Stash House CO, voluntarily recalled pre-rolled marijuana products on December 31, 2025, after regulators found unsafe pesticide levels — chlorfenapyr and fluopyram — exceeding legal limits, according to CBS News. That earlier recall reached almost 300 dispensaries across Colorado, including 75 stores in Denver alone, making this month's butane advisory the second safety flag against the company within roughly a year.
Mold-related recalls have become something of a recurring headline in Colorado's cannabis market this year. Hoodline previously reported on a statewide health advisory in February for flower from Sweetwater Group LLC that failed testing for yeast, mold, and Aspergillus across 31 dispensaries. That same month, state regulators expanded a separate advisory for HG LTD, sold under the Higher Grade brand, after tracing additional contaminated harvest batches sold between August 2025 and February 2026, according to Cannabis Equipment News.
Regulators Lack Power to Force Recalls
A joint investigation by ProPublica and The Denver Gazette, published earlier this month, found that Colorado regulators lack the statutory authority to force mandatory product recalls, instead relying on public advisories and voluntary industry cooperation. That same investigation found those advisories have taken an average of more than seven months to release after officials first receive safety complaints, according to ProPublica.
Between 2019 and early 2026, the state's Marijuana Enforcement Division issued more than 60 health advisories and recalls for cannabis products that failed to meet safety standards for pesticides, heavy metals, mold, or bacteria, per reporting from The Denver Post. The volume reflects a market under mounting financial strain — annual legal cannabis sales in Colorado fell from a high of $2.2 billion in 2021 to roughly $1.3 billion in 2025, a contraction Hoodline detailed in a report on how falling prices squeezed Denver shops into receivership.
State officials have also been focused on vape and concentrate safety more broadly this year. In April, the Marijuana Enforcement Division warned the industry about so-called inversion schemes, in which illicit operators chemically converted hemp-derived CBD into THC vapes using hazardous industrial solvents, a trend Hoodline covered as regulators moved to tighten testing requirements. This month's back-to-back advisories for Locol Love and Stash House CO came amid that broader focus on product-testing weaknesses and proposed reforms.
