Attorney General Dave Yost of Ohio is taking a stand against what he describes as anti-competitive tactics by several large cannabis companies with a newly filed antitrust lawsuit. This legal action comes after an employee in the Ohio cannabis industry blew the whistle in October 2024, leading to allegations that multistate cannabis operators are colluding to limit product choice and maintain high prices, as reported by the Ohio Attorney General Dave Yost's office. These practices not only damage consumers' wallets but also squeeze smaller, homegrown Ohio businesses out of the market, the lawsuit claims.

An investigation was spurred by the tip, which appeared to confirm that companies were engaging in reciprocal purchasing agreements. These large operators are accused of having agreed to prominently feature each other's products in Ohio dispensaries, effectively sidelining independent Ohio cultivators and processors. Nine major multistate operators, including Ascend Wellness, Ayr Wellness, and Green Thumb Industries, are named as defendants in the lawsuit.

"Our investigation uncovered allegations of an industry-wide scheme designed to push small Ohio businesses out of the market," Yost stated, according to the Ohio Attorney General Dave Yost's office. He argues this is a violation of Ohio’s Valentine Act, which aims to protect competition and consumers against this sort of orchestrated exclusion.

The lawsuit alleges these agreements date back to late 2022, when senior representatives from the accused companies reportedly met to discuss strategies to safeguard shelf space for each other, in light of increasing supply and dropping prices. Some of the companies are even alleged to have gone as far as establishing internal quotas to be able to reserve a fixed percentage of dispensary shelf space for partner companies' products, according to the complaint. The lawsuit is calling for injunctive relief to immediately halt such allegedly unlawful conduct.

With Attorney General Yost asserting that these actions have reduced product choice and quality for Ohio consumers, stifled innovation, and allowed the defendants to maintain or increase prices above competitive levels, all eyes are on the courts for how they will handle these allegations of industry manipulation. If proven, the implicated companies could face substantial consequences and a reshaping of the cannabis market landscape in Ohio and possibly beyond.
