Denver dispensary owners are being notified that the city will conduct random assessments of cannabis dispensaries located within the city "in the coming weeks."

The city's Department of Public Health & Environment will be testing products for contaminants—as a randomized safeguard for compliance. Just this week, as Westword reported, Herbal Wellness in nearby Lafayette, Colo., was hit with a product recall for "potentially unsafe levels of microbial contamination."

Read the full advisory here:

In the coming weeks, the Denver Department of Public Health & Environment (DDPHE) will be conducting an assessment in approximately 25 retail marijuana stores to evaluate contaminants in products on store shelves. DDPHE has worked with epidemiological partners at Denver Public Heath to create the assessment methodology. Participating stores will be randomly identified for inclusion in the assessment. Current METRC inventory lists for each store will be used to randomly identify samples of flower, trim/shake, and pre-rolls. Each sample will be tested for pesticides and total yeast and mold by a state- and ISO-certified marijuana testing facility. Results of their respective testing will be shared with each facility and will also be shared broadly within a write-up of results.
