Oklahoma Black-Market Marijuana Grew Rapidly During COVID
Oklahoma remains one of the largest sources of black-market marijuana in the United States, according to the Oklahoma Bureau of Narcotics. State officials say the problem escalated during the COVID-19 pandemic, when criminal organizations entered Oklahoma, obtained medical marijuana licenses, and then diverted product into illegal markets nationwide.
OBN officials say many of these operators exploited weak oversight during the early years of the medical marijuana program.
Thousands of Illegal Marijuana Grows Identified
At one point, investigators estimate there were nearly 8,000 illegal marijuana grow operations across Oklahoma. While enforcement actions have significantly reduced that number, OBN says more than 1,500 illegal grows are still active.
Untaxed Marijuana Drives Demand
Because black-market marijuana is untaxed and often produced using undocumented labor, OBN says it can be sold at lower prices, increasing demand outside the legal system.
Enforcement Efforts Continue Statewide
OBN continues joint operations with federal and local agencies, focusing on shutting down illegal grows and protecting legitimate licensed producers.
