Colorado Issues Health Advisory, Recall for Stash House CO Marijuana Products Sold at Nearly 300 Stores

Colorado regulators have issued a statewide health and safety advisory and voluntary recall involving marijuana products produced by CC Brands, LLC, which does business as Stash House CO, after additional testing found pesticide contamination above allowable limits. The advisory, issued Dec. 31 by the Colorado Department of Revenue in coordination with the Colorado Department of Public Health and Environment, covers both medical and retail marijuana concentrates used in vaporizer cartridges and infused pre-rolled products. Regulators said the affected products pose a potential risk to public health after testing identified pesticide levels that exceed limits set under Colorado Marijuana Rule 4-215.

According to the advisory, one production batch initially passed mandatory testing but was later retested and found to exceed state limits for the pesticide chlorfenapyr. Additional production batches were produced using marijuana concentrate that failed testing for another pesticide, fluopyram. Both substances are prohibited above strict thresholds in Colorado’s regulated marijuana market.

CC Brands worked with the state’s Marijuana Enforcement Division to initiate a voluntary recall of the affected products. The recall applies to infused pre-rolls and vaporizer cartridges manufactured under Regulated Marijuana Products Manufacturer Licenses 404R-00047 and 404-00302.

State officials said the recalled and potentially contaminated products were sold between Feb. 27, 2025, and Dec. 11, 2025, at 295 licensed marijuana stores across Colorado. The full list of affected retail locations spans nearly every major market in the state, including Denver, Colorado Springs, Aurora, Boulder, Fort Collins, Pueblo, and dozens of smaller communities.

The advisory identifies one production batch, number 1312, as contaminated. Additional batches — 1340, 1341, 1342, 1343, 1348, 1352, 1355, and 1375 — are listed as potentially contaminated and included in the recall as a precaution.

Consumers who purchased the affected products are urged to either destroy them or return them to the store where they were purchased for proper disposal. Regulators also emphasized the importance of checking product labels, which are required to display both the license number of the manufacturer and the assigned production batch number.

Health officials advised that anyone who experiences adverse effects after consuming the recalled products should seek medical attention and report the incident to the Marijuana Enforcement Division through its reporting process.

The advisory underscores Colorado’s ongoing enforcement of pesticide regulations within its marijuana program, including the use of follow-up testing when concerns arise after initial compliance testing. Regulators consider marijuana products that exceed pesticide limits to be a serious public health issue, particularly when those products are inhaled through vaporization or smoking.

State officials did not disclose how many units were sold or whether any illnesses have been formally linked to the affected products as of the advisory’s release. The recall remains active as the Marijuana Enforcement Division continues to monitor compliance and ensure that all affected products are removed from shelves.

Colorado consumers are encouraged to remain vigilant, verify product labels, and stay informed about health advisories issued by state regulators as part of the state’s regulated marijuana oversight system.
