A political committee spearheading a drive to pass a medical-marijuana ballot initiative raised slightly less than $52,000 from June 1 to June 24, according to a newly filed finance report. Nearly half the money, $25,000, came from the law firm Greenspoon Marder, which has offices in Florida and other states. The committee, known as People United for Medical Marijuana, or United for Care, has been heavily funded by Orlando attorney John Morgan, its chairman. But Morgan and his law firm did not contribute money to the committee during the recent reporting period. More than $3 million poured into the committee last year during a petition-gathering effort to get the initiative on the November 2016 ballot. The initiative, if approved by voters, would broadly legalize medical marijuana in the state. Meanwhile, an opposition group, known as the Drug Free Florida Committee, did not report raising money from June 1 to June 24. That came after Drug Free Florida received $500,000 in May from St. Petersburg real-estate developer Mel Sembler.
