The vote on legalizing recreational marijuana in Oklahoma is coming this week.

Supporters say many in Oklahoma's medical cannabis industry are struggling because of a limited market. Industry proponents hope an influx of Texas consumers will be a boon for a market that’s become saturated. The question on Tuesday's ballot is being opposed by a group of law enforcement officers, clergy and prosecutors. That group is led by former Oklahoma Gov. Frank Keating, an ex-FBI agent. Current Oklahoma Gov. Kevin Stitt also opposes the state question. If approved, Oklahoma will become the 22nd state to legalize cannabis for adults.
