Thirteen strains of marijuana sold from November 2018 to January 2019 at a licensed medical marijuana provisioning center in Ypsilanti are being recalled, state officials announced Friday, Feb. 1.

The medical marijuana failed to meet state standards when tested -- and some of the strains were contaminated with the heavy metals cadmium and arsenic, according to the Bureau of Marijuana Regulation.

The recall affects medical marijuana sold at The Patient Station at 539 South Huron in Ypsilanti from Nov. 14, 2018, to Jan. 22, 2019.

This is the fifth mandatory recall this year of marijuana grown by caregivers and sold to patients untested.

During December 2018, state regulators specifically allowed licensed provisioning centers to sell untested marijuana grown by caregivers to patients in the name of patient access. Once the state required caregiver product to be tested after Jan. 1, tests revealed a total of 48 pounds of marijuana was contaminated with chemicals, E. coli and mold, among other issues. Four mandatory recalls were issued within two weeks.

Two weeks ago Bureau of Marijuana Regulation officials decided to allow provisioning centers to again purchase marijuana from caregivers and sell it untested until March 31, and to allow a number of unlicensed provisioning centers to temporarily reopen. Regulators were responding to a medical marijuana shortage in the state.

The state’s actions met backlash from every state-licensed lab in Michigan. The Michigan Coalition of Independent Cannabis Testing Laboratories, as well as two provisioning centers; five processors; two secure transporter companies; growers BlueSol Biomedical, Pure Green and the two biggest growers in the state -- Green Peak Industries and VB Chesaning -- sent a letter to regulators Jan. 18 urging them to change their minds.

“Michigan’s most vulnerable patients are buying purported medical cannabis products that could legitimately harm them," wrote Ben Rosman, CEO of PSI Labs, in the letter sent on behalf of the lab coalition.

No patients reported illness to the state, said bureau spokesman David Harns. State officials have encouraged patients to seek out their own testing of products they buy -- and patients must sign a waiver before buying any untested marijuana.

Anyone with the recalled products should return them to the provisioning center for proper disposal.

In January more than more than 48 pounds of medical marijuana was recalled, according to the Bureau of Marijuana Regulation.

Here are the past four recalls of caregiver product:

Jan. 4, the state issued a voluntary recall of five different products sold at approximately 15 or more licensed provisioning centers due to computer input errors that did not show if the products had been tested.
