Colorado marijuana regulators issued a recall for two brands of THC vaporizers on June 1, citing banned flavor compounds in the vape oil.
According to a health and safety order from the state Marijuana Enforcement Division, around 44 batches of vaporizer devices produced by Workhorse Global LLC and WH Acoma LLC are being recalled after “the identification of non-botanically derived compounds.” The vape products were sold under the brands PAX and Eureka Vapor at approximately 320 dispensaries and hospitality lounges across Colorado from Aug. 14, 2025, to May 31 of this year.
Several of the stores listed in the recall have since closed or been taken over by new management, such as Simply Pure’s shuttered dispensary in Denver’s Highland neighborhood and a handful of former Green Dragon stores around the metro, which now operate under the Everyday Weed banner. Still, state regulators would like consumers to double-check their vapes, just in case.
“Consumers who have this affected marijuana in their possession should destroy it or return it to the Regulated Marijuana Store from which it was purchased for proper disposal. Consumers who experience adverse health effects from consuming the Regulated Marijuana should seek medical attention immediately and report the event to the Marijuana Enforcement Division by submitting a MED Reporting Form,” the recall states.
The recalled vapes will have one of two license numbers on their packaging: 404R-00576 or 404R-00523.
Banned vape additives
Colorado began banning certain vape additives in 2019, and has expanded the list of prohibited ingredients over the last seven years.
According to MED regulations, approved botanically-derived compounds are organic chemicals that “include, but are not limited to, terpenes, terpenoids, ketones, esters, and other molecules which are naturally occurring in plants and are used to affect the flavor and aroma” of marijuana products.
The MED tells Westword that the vape products were found to contain “terpene blends that contained artificial and/or synthetic ingredients.”
Terpenes are aromatic compounds found in cannabis and other plants, and are responsible for a strain’s smell and flavor. Vape companies can add terpenes that aren’t extracted from cannabis to their products, but they must come from natural sources.
“The investigation is open and ongoing,” reads the MED recall. “We encourage all consumers who purchased a vaporizer delivery device of these brands to check their labels to determine if they are included in the affected batches.”
In statements to Westword, Eureka and PAX say their respective companies are addressing the matter with their suppliers.
“At Eureka, consumer trust and product integrity have always been at the center of our business. We are working closely with our licensed manufacturing and retail partners to proactively address a Colorado regulatory matter involving a small percentage of our products. While there have been no reported illnesses or known public health concerns associated with these products, we fully support the regulatory process and are committed to handling this matter responsibly, transparently, and with the urgency our customers and partners expect from us,” a statement from Eureka says.
“Consumer safety, product quality, and scientific rigor are foundational to everything we do. We have voluntarily complied with the Colorado Marijuana Enforcement Division’s recall order and are working closely with our manufacturing and retail partners to support the process. This recall was not initiated because of any reported consumer injuries, adverse events, contamination or product safety concerns. Our terpene blends have been extensively tested for inhalation safety by our supplier and are widely used across the industry. Importantly, we believe the products in question were formulated in compliance with Colorado regulations and using inactive ingredients that are permitted under established governmental regulatory frameworks. While we respect the MED’s role and are cooperating fully, we look forward to continuing a constructive dialogue with regulators and reaching a resolution grounded in scientific rigor, regulatory clarity, and due process,” a statement from PAX says.
This is the 13th marijuana-related recall issued in Colorado so far this year.
