OKLAHOMA CITY — The rollout of statewide medical and recreational marijuana programs typically is a grindingly slow process that can take years. Not so in Oklahoma, which moved with lightning speed once voters approved medical cannabis in June.

The ballot question received 57 percent support and established one of the nation’s most liberal medical pot laws in one of the most conservative states. Six months later, the cannabis industry is booming.

Farmers and entrepreneurs are racing to start commercial grow operations, and the state is issuing licenses to new patients, growers and dispensary operators at a frantic pace. Retail outlets opened just four months after legalization.

By contrast, voters in North Dakota, Ohio and neighboring Arkansas approved medical pot in 2016 but have yet to see sales begin amid legal wrangling and legislative meddling.

“I think we really are the wild, wild West in many respects,” said attorney Sarah Lee Gossett Parrish, whose firm in Norman represents several cannabis businesses. “Here in Oklahoma, we’re a pretty independent constituency. We are primarily a red state, but we don’t like a lot of government controls.”

Indeed, unlike virtually every other state, Oklahoma officials created no list of qualifying medical conditions for people to get medicinal marijuana. That has prompted a flood of applications for personal licenses to purchase pot.

Since August more than 22,000 have been approved and thousands more are in the pipeline. There are now 785 licensed dispensaries. Some small towns have as many as a half-dozen. Norman and Stillwater, the state’s two largest college towns, have 45 combined.
