LANSING, MI -- Nearly 15,000 marijuana vaping products were recalled after being sold at medical marijuana dispensaries in Detroit and Bay City, the Michigan Marijuana Regulatory Agency says.

Some of the vaping cartridges were never tested for vitamin E acetate; others failed testing.

Elite Wellness, 3389 S. Huron Road in Bay City, sold 10,000 of the recalled cartridges and Plan B Wellness, 20101 Eight Mile in Detroit, sold 4,608 of the recalled cartridges, according to the Marijuana Regulatory Agency.

The Michigan Marijuana Regulatory Agency on Nov. 22 banned the sale of all vaping products pending testing for vitamin E acetate. It also banned vitamin E acetate as an ingredient in any new vaping cartridges produced by licensed growers and processors.

The state hasn’t said how some of the vaping cartridges avoided vitamin-E acetate testing.

“The most important thing right now is that patients who purchased the recalled medical marijuana product are made aware of the fact that it was not tested for vitamin E acetate,” Marijuana Regulatory Agency spokesman David Harns said. I am unable to discuss any possible investigations."

The Centers for Disease Control “strongly linked” vitamin-E acetate to lung illnesses that caused nearly 2,700 hospitalizations and 60 deaths nationally. Vaping manufacturers used the ingredient as a filler to increase product volume and thereby profits.

Anyone who purchased the recalled products is asked to return them to the retailer.
