Michigan Cannabis Testing Lab License Revoked Under Settlement with Officials

The license of Lansing, Michigan-based Viridis, a cannabis testing laboratory, has been revoked under a settlement reached last week between the company and state officials, the Detroit Free Press reports.

In addition to permanently revoking the license of the company’s Lansing-based testing lab, which was at the heart of a massive 2021 cannabis product recall that affected over 400 retailers in the state, the settlement permanently bars the company’s three majority owners — Todd Welch, Gregoire Michaud, and Michele Glinn — from participating in the Michigan cannabis industry. The agency noted at the time ff the recall that the testing lab had provided “inaccurate and/or unreliable results,” and that nearly all products

Viridis operated two testing lab locations in the state — one in Lansing, and one in Bay City — and minority investors in the company are reorganizing into a separate entity to run the company’s Bay City site, the report said.

“This is justice, plain and simple. Viridis failed to uphold the standards required of marijuana safety compliance facilities in Michigan. Viridis circumvented the rules. Their majority owners will never operate in this space again, and the Michigan cannabis industry will be stronger for it.” — Brian Hanna, CRA Executive Director, in a press release

Michigan retailers have noted that consumers are purchasing more cannabis in 2025, although total sales have been declining due to product oversupply.

The multistate cannabis operator Terrascend announced last month it would exit the Michigan industry.
