Just weeks after Oklahomans voted for medical marijuana, another initiative petition could expand the state's laws to include recreational use.

Supporters of State Question 797 began gathering signatures before the June 26 statewide ballot that saw more than 56 percent of voters approving of medical cannabis. Isaac Caviness, president of Green the Vote, hopes that enthusiasm will translate to his signature-gathering campaign, which also includes a separate state question placing medical marijuana in the Oklahoma Constitution.

In the two months since the campaign started, Green the Vote has amassed more than 80,000 signatures. They have until Aug. 8 to reach 123,725.

"The response we're getting is people of Oklahoma have gotten educated as far as what recreational has done for Colorado," he said, referring to the neighboring state that legalized recreational marijuana in 2012. "And with all of the budget shortfalls we've had and our teachers striking at the Capitol trying to demand funds for schools, I think the citizens of Oklahoma are looking at recreational as a possible revenue source."
