Oklahoma votes to legalize medical marijuana

Voters in Oklahoma have approved a measure to legalize medical marijuana, becoming the 30th U.S. state to do so. Opponents argue that the proposal is too loosely written and could enable recreational use.

About 56% of voters cast a ballot in support of State Question 788, according to initial results released by the Oklahoma State Election Board. Nearly 90 percent of ballots had been counted by 9:30 p.m.

The measure would permit doctors to recommend a patient, who is at least 18 years old, for a state-issued medical marijuana license. A license holder would be allowed to legally possess up to 3 ounces of the drug, 6 mature plants and 6 seedlings. Counties or cities may increase those limits.

The measure has faced opposition from law enforcement and political leaders, including Governor Mary Fallin, who claims it would essentially allow recreational use, according to the Associated Press. She warned that, if approved, she will call lawmakers into a special session to develop rules to regulate the industry.
