In honor of 4/20, which some recognize as a marijuana holiday, here's a look back at Oklahoma's history with it.
December 2014: Oklahoma Attorney General Scott Pruitt joined Nebraska’s Jon Bruning in asking the U.S. Supreme Court to declare Colorado’s legalization of marijuana unconstitutional.
May 2015: A medical pilot program using cannabidiol — a nonintoxicating derivative of marijuana — was approved in a bill signed by Gov. Mary Fallin.
June 2018: 57 percent of voters passed State Question 788 in June 2018. The measure made it legal to use, sell and grow marijuana for medicinal purposes.
State Question 788 went into effect in 2018, but there are some things still illegal under Oklahoma's medical marijuana laws.
January to July 2020: The state and local taxes from Oklahoma medical marijuana exceeded $80 million.
September 2020: The Oklahoma Supreme Court struck down an initiative petition seeking to legalize recreational marijuana.
December 2020: Medical marijuana sales tax boosts Tulsa coffers amid COVID-19 revenue losses; city on track to collect $4.8 million in sales tax on the sale of medical marijuana through June 2021.
