On Tuesday, voters in Oklahoma approved a measure that will make medical cannabis legal in the state with over 56% popular support.

The referendum, known as SQ 788, will allow patients 18 and older to use medical cannabis to treat their conditions with a recommendation from their doctor, and individual under the age of 18 would need the signatures of two physicians and his or her parent or legal guardian. Physicians can recommend cannabis for any condition for which they think cannabis would be a helpful treatment.

With the addition of Oklahoma, there are now effective medical cannabis laws in 30 states, as well as the District of Columbia, Guam, and Puerto Rico. A total of 46 states allow for the medical use of cannabis in some form.

“In spite of a well-financed and misleading opposition campaign, Oklahoma voters proved that medical cannabis is no longer a controversial issue by enacting a sensible law at the ballot box tonight.” said Aaron Smith, executive director of the National Cannabis Industry Association (NCIA). “The passage of this law is not only a great victory for some of the Sooner State’s most vulnerable citizens – it will also create new business opportunities as the state’s underground market for medical cannabis is replaced by licensed businesses with the potential to create thousands of jobs and millions in new tax revenue,” continued Smith.

About SQ 788:
Oklahoma state will establish rules governing the licensing and regulation of facilities to cultivate, process, and dispense medical cannabis, and allows patients to cultivate limited amounts of medical cannabis at home.

The passage of SQ 788 marks the first time that a state medical cannabis ballot initiative has been approved by voters in an electoral primary. Observers were skeptical of the initiative passing in an unprecedented election cycle, particularly given strong and well-funded efforts from opponents to the referendum in the months before the vote.
