Federal cannabis prohibition has fueled unnecessary arrests, prison sentences, and criminalized millions of people. Nearly a quarter of a million people are arrested yearly exclusively for cannabis possession across the United States, even in states where cannabis has been legalized. Despite the majority of US citizens supporting cannabis legalization and state-level regulation, cannabis remains illegal at the federal level. Outdated laws hinder research, regulate businesses unfairly, and lead to the imprisonment of people for unjust reasons.
