Missouri’s largest marijuana company is facing another antitrust lawsuit accusing it of using a network of affiliated companies to dominate the state’s cannabis market and drive up prices for consumers.
According to reporting by Missouri Independent, a Kansas City consumer recently filed a class-action lawsuit against Good Day Farm and more than 40 affiliated limited liability companies.
The lawsuit alleges the company used a complex structure of business entities to gain control over a large share of Missouri’s recreational marijuana industry while limiting competition from other brands and retailers.
The complaint was filed in Jackson County Circuit Court by Damon Frost Jr., a Kansas City contractor, on behalf of Missouri consumers who purchased recreational marijuana products from the defendants.
“Defendants’ illegal scheme has successfully limited choice and locked out third party brands,” the lawsuit states, “thereby decreasing competition and increasing costs for Missouri consumers.”
Second lawsuit in two weeks
The new filing comes just weeks after a separate lawsuit from two Missouri cannabis manufacturers accused Good Day Farm and related companies of operating what plaintiffs described as an “illegal cartel”.
That earlier lawsuit alleged the company and affiliated entities controlled more than 60 of Missouri’s 224 dispensary licenses – more than one-quarter of the state’s market.
Missouri voters approved recreational marijuana legalization in 2022, but questions have continued surrounding how ownership limits within the state’s cannabis industry are interpreted and enforced.
Under Missouri’s recreational marijuana system, companies are generally prohibited from controlling more than 10 percent of dispensary licenses statewide.
However, critics argue the use of multiple LLCs and affiliated ownership structures may allow companies to expand beyond what voters originally intended.
According to Missouri Independent, publicly available business records show Good Day Farm expanded aggressively after recreational marijuana legalization passed, including through acquisitions involving dispensaries, manufacturing facilities and cultivation sites.
Company denies wrongdoing
Good Day Farm denied the allegations.
In a statement provided to Missouri Independent, company spokesperson Lisa Weser called the claims “baseless and without merit”.
“Our company operates in full compliance with all applicable Missouri state laws and regulations, and we will vigorously defend that record,” the statement said.
The company also said it would not allow “aggressive legal tactics” to interfere with operations or customer service.
Broader debate over cannabis consolidation
The lawsuits highlight growing concerns nationally about consolidation within the cannabis industry, where critics say large multi-state operators increasingly dominate markets originally promoted as opportunities for small local businesses.
Supporters of tighter regulation argue excessive concentration can reduce competition, increase prices and limit opportunities for independent operators.
At the same time, large cannabis companies argue that scale and investment are necessary to operate within heavily regulated markets requiring substantial capital, compliance systems and distribution infrastructure.
Missouri regulators confirmed to Missouri Independent that the state no longer requires certain “common control” affidavits previously used to monitor ownership overlap after recreational marijuana legalization amended the state constitution.
The lawsuits are likely to intensify scrutiny over how Missouri’s cannabis market is structured and whether current regulations adequately prevent excessive concentration of ownership.
