But some Republicans in those states have continued to fight against medical marijuana approved by voters. In South Dakota, a Republican state lawmaker unsuccessfully pushed a bill this year to repeal voter-approved medical marijuana. Karen O’Keefe, director of state policies at the Marijuana Policy Project, said polling has shown a majority of Republicans support legalized medical marijuana. The medical marijuana law passed by Nebraska voters in November required that licenses be issued by Wednesday. In a March editorial, he said “marijuana is easily abused and is not safe to consume even under medical supervision.”Crista Eggers, who led the medical marijuana ballot initiative, argued a “black market” thrives when marijuana for medical use is too severely restricted.
