Michigan medical marijuana dispensaries were unable to complete sales Tuesday, Feb. 18, due to a malfunction with the statewide tracking and monitoring computer system.

The “patient lookup is down,” Marijuana Regulatory Agency spokesman Matthew Erickson confirmed Tuesday night. “We are working with Metrc to remedy the problem.”

The problem doesn’t appear to have impacted recreational marijuana sales.

Metrc is the name of the state-mandated software program used to track marijuana products, as well as to verify registered patients and caregivers. The system also ensures the patients and caregivers don’t exceed their 2.5-ounce-per-day purchase limit. Registered patients are additionally restricted to no more than 10 ounces of marijuana purchase per month.

It’s unclear what caused the issue or when it will be corrected, but some medical patients reported receiving text notices that stores they shop at were no longer making sales until the issue is corrected.

The Marijuana Regulatory Agency said an update on the situation is likely to be available Wednesday morning.

As of Jan. 31, Michigan had 267,068 registered medical marijuana patients 36,136 caregivers. [Read more at MLive.com]
