Colorado-based Bronnor Corp. has voluntarily recalled cannabis vaporizer pens over concerns about possible ethanol contamination.

The Colorado Department of Taxation issued a public safety advisory Jan. 24 stemming from potentially unsafe levels of residual ethanol in a Bronnor-manufactured product, Bullet Concentrates, according to Denver alternative weekly Westword.

The potential contamination of 26 vape pens from four different batches prompted Bronner to recall the product. The products were limited to the Colorado market.

Bronner spokeswoman Jennifer Price told Marijuana Business Daily the situation stemmed from “conflicting results from separate laboratories.”

She said the company is submitting the product for “further testing for definitive clarification” about the possible contamination.

Denver-based Bronnor manufactures infused products for Colorado companies that don’t have the facilities to do so. The company’s products include vaporizer cartridges, edibles, topicals and tinctures.

Colorado is beginning mandatory testing of cannabis products in February for residual solvents, including ethanol.
