Oklahoma is now the biggest medical marijuana market in the country on a per capita basis. More than 360,000 Oklahomans—nearly 10 percent of the state’s population—have acquired medical marijuana cards over the last two years. By comparison, New Mexico has the country’s second most popular program, with about 5 percent of state residents obtaining medical cards. Last month, sales since 2018 surpassed $1 billion.

To meet that demand, Oklahoma has more than 9,000 licensed marijuana businesses, including nearly 2,000 dispensaries and almost 6,000 grow operations. In comparison, Colorado—the country’s oldest recreational marijuana market, with a population almost 50 percent larger than Oklahoma—has barely half as many licensed dispensaries and less than 20 percent as many grow operations. In Ardmore, a town of 25,000 in the oil patch near the Texas border, there are 36 licensed dispensaries—roughly one for every 700 residents. In neighboring Wilson (pop. 1,695), state officials have issued 32 cultivation licenses, meaning about one out of 50 residents can legally grow weed.

What is happening in Oklahoma is almost unprecedented among the 35 states that have legalized marijuana in some form since California voters backed medical marijuana in 1996. Not only has the growth of its market outstripped other more established state programs but it is happening in a state that has long stood out for its opposition to drug use. Oklahoma imprisons more people on a per-capita basis than just about any other state in the country, many of them non-violent drug offenders sentenced to lengthy terms behind bars. But that state-sanctioned punitive streak has been overwhelmed by two other strands of American culture—a live-and-let-live attitude about drug use and an equally powerful preference for laissez-faire capitalism.
