Ken Griffin, the CEO of Citadel hedge fund, has pledged $12 million to oppose Florida’s recreational cannabis legalization measure, known as Amendment 3. This substantial donation is part of a larger $20 million campaign aimed at defeating the initiative, which seeks to allow adults aged 21 and older to possess up to three ounces of marijuana. Griffin’s involvement has reignited the debate over cannabis legalization in Florida, raising questions about the influence of wealthy donors in political campaigns and the future of cannabis policy in the state.
