The Supreme Court is set to decide whether "habitual drug users" can be prohibited from possessing firearms under the 2nd Amendment. The case challenges the federal law that restricts gun rights for those classified as unlawful users of drugs, a policy supported by the Trump administration, which argues that it aligns with historical restrictions on gun ownership for individuals deemed dangerous. Critics highlight the conflict between state-level legalization of substances like marijuana and the existing federal laws that impose severe penalties for gun possession.
