OKLAHOMA CITY — Senate Bill 640 by Cynthia Roe, R-Lindsay, has passed the House Alcohol, Tobacco and Controlled Substances Committee, which aims at addressing abandoned and improperly maintained medical marijuana grow operations. The measure would require licensed medical marijuana businesses to properly remove and dispose of surface trash, debris and waste tied to their operations. It also would mandate that commercial growers clean up sites within 30 days after a license is revoked, expired or becomes inactive. Failure to do so would classify the property as a public nuisance, allowing for abatement. "Over the interim, I had the opportunity to hear directly from landowners and law enforcement throughout our communities who spoke about the real challenges these abandoned grow sites are creating," Roe said. "We need to set clear expectations and make sure marijuana operators clean up after themselves so these properties do not become hazards." The measure would also establish fines for violations and gives the Oklahoma Medical Marijuana Authority the authority to implement rules and enforcement measures. Roe, who serves as chair of the House Public Health Committee, said the amendment stems from extensive research and input gathered during an interim study. "We learned a lot through the interim study process, and it was clear that stronger standards were needed," Roe said. "This bill is about putting the responsibility where it belongs. It also would give the state tools to address bad actors while supporting responsible businesses that are doing things the right way to protect our land." The measure now moves to the House Health and Human Services Oversight Committee for further consideration.
