Oklahoma Abandoned Marijuana Grows Face Legislative Review
Oklahoma Abandoned Marijuana Grows Under Review as Lawmakers Consider Cleanup and Reuse
Oklahoma lawmakers will examine what should happen to abandoned commercial marijuana grow operations as the state continues dealing with the aftermath of a dramatic contraction in its medical marijuana industry. State Sen. Darcy Jech is leading an interim study Tuesday focused on how abandoned grow facilities are currently managed and what Oklahoma could do to address properties left with deteriorating structures, equipment, chemicals and other potential hazards.
The Oklahoma abandoned marijuana grows study comes after years of enforcement actions, licensing changes and stricter regulatory requirements reduced the number of commercial marijuana operations across the state. Oklahoma once had more than 9,000 licensed growers, while state officials reported fewer than 1,200 remaining by mid-2026.
Oklahoma Abandoned Marijuana Grows Get Legislative Review
Jech's Interim Study 2026-59, titled "Management of Abandoned Commercial Marijuana Grow Facilities," is scheduled before the Senate Business and Insurance Committee at 9 a.m. Tuesday, October 6.
The official Oklahoma Senate meeting agenda shows lawmakers will hear from representatives of several agencies that encounter different aspects of the abandoned-grow problem.
Scheduled speakers include Oklahoma Medical Marijuana Authority Chief Administrative Officer Barrett Brown, Department of Environmental Quality Deputy Executive Director Madison Miller, Oklahoma Insurance Department Deputy Commissioner Ashley Scott, Oklahoma Bureau of Narcotics Public Information Officer Mark Woodward and Dane Towery of the Oklahoma Attorney General's Organized Crime Unit.
Bringing those agencies together could help lawmakers determine where responsibility currently falls when a marijuana operation closes, loses its license or is shut down by law enforcement.
The issue can become particularly complicated when a former grow property contains equipment, marijuana waste, chemicals or structures modified specifically for commercial cultivation.
The study does not itself change Oklahoma law. Interim studies allow legislators to gather testimony and examine potential policy changes before legislation is considered during a future legislative session.
Number of Oklahoma Marijuana Grow Operations Has Plummeted
Oklahoma's commercial marijuana industry expanded rapidly following legalization of medical marijuana in 2018.
At its peak, the Oklahoma Medical Marijuana Authority reported roughly 13,000 licensed marijuana businesses of all types across the state.
That number has fallen sharply as Oklahoma increased inspections, imposed additional licensing requirements and state and federal law enforcement agencies targeted illegal operations.
The Attorney General's Organized Crime Task Force reported this summer that Oklahoma had fewer than 1,200 licensed marijuana grows, compared with more than 9,000 when Attorney General Gentner Drummond took office in 2023.
Enforcement has continued throughout 2026.
In July, the task force shut down five illegal marijuana grow operations in Woodward, seizing more than 30,000 plants and more than 200 pounds of processed marijuana.
Earlier operations targeted grows in Prague, Oklahoma City and other communities.
Oklahoma has also maintained a moratorium on new grower, processor and dispensary licenses. The moratorium began in 2022 and was extended this year through August 1, 2028, unless OMMA determines pending licensing reviews, inspections and investigations have been completed.
Commercial growers must also meet requirements involving certificates of compliance, ownership, background checks, security and other regulatory standards.
As businesses close or illegal operations are dismantled, however, another question emerges: what happens to the property afterward?
That is the problem Jech's study is intended to examine.
Cleanup, Environmental Hazards and Reuse Are Part of the Discussion
Abandoned marijuana operations can present issues far beyond an empty building.
Commercial cultivation can involve extensive electrical systems, irrigation equipment, fertilizers, pesticides and other materials. Processing operations can involve additional chemicals and equipment requiring proper handling.
Depending on what was conducted at a particular property, abandoned sites can therefore present different environmental, fire, structural or public-safety concerns.
Oklahoma already regulates disposal of marijuana waste. The Oklahoma Department of Environmental Quality's marijuana waste guidance explains that OMMA regulates medical marijuana waste while DEQ oversees permitted solid-waste disposal facilities that may receive marijuana and other waste.
The broader challenge is determining responsibility when an operation is no longer functioning and property or materials are simply left behind.
Lawmakers are expected to examine whether existing state authority is sufficient, who should bear cleanup costs and how agencies should coordinate when an abandoned facility presents an immediate hazard.
Another question is whether some properties can be repurposed rather than simply demolished or left vacant.
Former commercial grows can include warehouses, greenhouses, agricultural structures and other buildings with substantial investments in electrical, water and climate-control infrastructure. Depending on their condition and location, some could potentially be converted to other agricultural, industrial or commercial uses.
Others may require significant remediation before they can safely be occupied again.
The issue gained additional attention following a deadly explosion at a former marijuana-related operation in Sand Springs. OMMA said in September that its most recent inspection of the licensed business had found it nonoperational and no evidence of illicit activity at that time. Authorities later said unsafe, illegal operations were involved in the explosion, which killed two people.
That case underscores the distinction lawmakers will have to consider between a business that has legally ceased operations and a property where unregulated activity may continue after a license is no longer active.
