The Colorado cannabis market received an unexpected shock last week when StayCon, the Pueblo County manufacturer that sells vapes under the Craft label, announced a voluntary recall of 49 vape cartridges. Among the affected lines are the popular Maui Wowie and Grape Gorilla flavors, some of which have been on dispensary shelves for more than a year and a half.
The recall was triggered by a discovery that a botanically-derived flavoring compound used in the devices contained methylene chloride. The chemical, traditionally employed to strip paint, is classified by the Environmental Protection Agency (EPA) as a probable carcinogen and has been slated for a ban on most uses.
How the contamination was uncovered
In August, Denver-based Bona Fides Laboratory was conducting routine screens for pesticides and mold when owner David Mathis identified traces of methylene chloride in several Craft cartridges. Mathis immediately alerted both StayCon and the Colorado Marijuana Enforcement Division (MED). He later explained that the laboratory had been prepared to run the expanded solvent panel—covering methylene chloride and 30 other solvents—since the beginning of July, but the state’s public-health department requested additional time before certifying labs for the new protocol.
Mathis warned, “How many samples were not tested but have contaminants in them and were passed to the public?” His criticism underscores a broader tension: the testing rule designed to catch such solvents was supposed to be live in July, aligning Colorado with the 24 states that already require similar screening. Yet the agency delayed implementation, citing the need for more time to review lab certifications.
Regulatory response and lingering loopholes
Despite the clear health risk, the Marijuana Enforcement Division has not issued a consumer-facing alert. Kyle Boyd a spokesperson for MED, responded to inquiries by stating that the agency “does not comment on investigations.” The lack of a public warning fuels concerns that contaminated products may continue to circulate while the state finalizes its testing framework.
Compounding the issue, Colorado’s current regulations still allow manufacturers to select the samples sent to laboratories and to choose the labs themselves. Earlier in the year, regulators floated a proposal to shift sample collection to independent technicians, but industry pushback over cost concerns caused the plan to be shelved. This sampling loophole means that even as the new solvent panel rolls out at the end of the month, manufacturers retain significant influence over what gets tested.
Timeline of key events
Several milestones provide context for the recall:
- May 15, 2026 – A senior MED official acknowledged in a meeting that the volume of chemically converted hemp marketed as marijuana exceeds public estimates.
- April 13, 2026 – State regulators announced a crackdown on illegal hemp-derived THC products, citing tax avoidance and public-safety risks.
- Feb. 6, 2026 – Regulators debated abandoning the self-sampling system in favor of independent collection.
- – The originally scheduled launch date for the expanded solvent testing panel.
- August 2026 – Bona Fides Laboratory detected methylene chloride, prompting the recall notice issued six weeks later.
- End of this month (2026) – Implementation of the new testing rules is expected to begin.
These dates illustrate a pattern of delayed regulatory action that allowed a hazardous solvent to reach consumers.
StayCon, operating under the Craft brand, has not responded to further questions about the recall. Meanwhile, consumer-confidence groups are urging the state to accelerate the certification of laboratories and to close the sampling loophole that gives manufacturers discretion over which batches are examined.
As Colorado moves toward stricter testing standards, the episode serves as a cautionary tale about the consequences of regulatory lag in a market that continues to expand rapidly.
