Key takeaways
Colorado MED has issued three Craft/Staycon vaporizer health and safety advisories since Sept. 25, 2026 covering solvents, unapproved flavoring and pesticides.
The Oct. 8 expanded advisory alone covers sales at 504 stores from Nov. 5, 2025 through Oct. 7, 2026 — match license numbers and batch IDs, not nicknames.
As of Oct. 9, CDPHE had logged 38 adverse-event reports; the agency is still verifying product linkage and has not proven causation for every case.
Retailers should stop sale of listed lots, accept returns or destroy product, and point customers with symptoms to medical care plus the MED reporting form.
Colorado’s marijuana regulators have turned a late-September solvent notice into a multi-wave public health action. Retailers and floor staff are now chasing three overlapping Craft/Staycon vaporizer advisories while state health staff work through a stack of adverse-event reports.
The Colorado Marijuana Enforcement Division (MED) first flagged StayCon LLC doing business as Craft on Sept. 25, 2026 for methylene chloride in vaporizer delivery devices. On Oct. 8 it expanded that action for synthetic unapproved flavoring, and on Oct. 13 it issued a separate pesticide advisory. Westword reported that CDPHE spokeswoman Gabi Johnston said the agency had received 38 adverse-effect reports as of Oct. 9.
Three Craft vaporizer advisories in three weeks
According to Westword, the Sept. 25 solvent advisory covered 87 batches sold at 405 stores, with no adverse reports noted at that time. MED then posted an Oct. 1 update tying adverse health events to the StayCon HSA.
The Oct. 8 expanded advisory, republished in full by Colorado Cannabis Times, named manufacturer licenses 404R-00170 and 404-00489 and said affected product sold at 504 stores between Nov. 5, 2025 and Oct. 7, 2026. Contaminants named across the wave include methylene chloride; a synthetic flavoring ingredient that is not botanically derived and not listed on the FDA Inactive Ingredient Database for inhalation; and — in the Oct. 13 notice summarized by Westword — the pesticide chlorfenapyr above Colorado’s acceptable limits, sold at about 226 stores from Sept. 26, 2025 to July 11, 2026.
Date | Advisory focus | Scope noted in sources |
|---|---|---|
Sept. 25, 2026 | Methylene chloride | 87 batches; 405 stores (Westword) |
Oct. 8, 2026 | Expanded flavoring + solvent batches | 504 stores; Nov. 5, 2025–Oct. 7, 2026 |
Oct. 13, 2026 | Pesticide (chlorfenapyr) | ~226 stores; investigation ongoing |
As of Oct. 9 | CDPHE adverse-event count | 38 reports; mostly headaches and respiratory discomfort |
“The CDPHE and DOR deem it a threat to public health and safety when ingredients used in the manufacture of Vaporizer Devices are not botanically derived or listed on the FDA Inactive Ingredient Database for inhalation.”
What retailers and consumers are told to do
The Oct. 8 MED advisory instructs customers and stores to check labels for license numbers and production batch IDs, stop use, and destroy product or return it to the regulated marijuana store of purchase. Anyone with adverse effects is directed to seek medical care and report through the MED reporting form — a compliance workflow, not a claim about any product’s medical effects.
Westword also quoted Johnston saying CDPHE continues interviewing reporters “to confirm the products consumed are related to those listed in the health and safety advisory.” Treat the 38 reports as filings under review, not proven causation for every case.
What this means for operators
Pull every Craft/Staycon SKU against current HSA batch lists, matching license numbers and production batch IDs.
Stop sale, quarantine and document returns or destruction for listed lots.
Train floor staff on the reporting path: stop use, seek care for symptoms, file the MED form, escalate to a manager.
Review ingredient COAs and residual-solvent panels with manufacturers and labs. MED Industry Bulletin 26:10 on inactive ingredients is dated Oct. 7, 2026; IB 26:09 covers residual solvents.
Expect follow-up notices. Company statements attributing methylene chloride to contaminated α-pinene or a later recall to synthetic geraniol are claims, not verified causes.
What this means for cannabis workers
Budtenders and inventory leads are the front line for batch-number checks. If you work retail in Colorado, it’s reasonable to ask which Craft/Staycon lots are still on the floor, where the current MED advisory PDFs live, and how your shop logs returns and adverse-event referrals.
The bigger picture
Colorado’s three-wave Craft action lands next to fresh MED guidance on inactive ingredients and residual solvents. Potency tests alone do not clear a vaporizer when solvent panels, pesticide limits and inhalation-ingredient rules all apply.
