The United States Supreme Court on Thursday issued a unanimous decision in favor of a Texas-based marijuana user who wants to legally own a gun.The justices ruled in favor of Ali Daniel Hemani, who argued that a law prohibiting firearms ownership for anyone who illegally uses drugs violates the Second Amendment. Hemani was not charged with any other crime or accused of using a weapon while under the influence.The decision is a blow to the Republican administration of US President Donald Trump, which had defended the 1968 law while opposing other gun restrictions.The law was also cited in the case against Hunter Biden, who was convicted in Wilmington, Delaware, of purchasing a gun while addicted to cocaine in 2018. He was later pardoned by his father, then-President Joe Biden, a Democrat.The decision comes amid a series of firearms cases before the Supreme Court following its landmark 2022 decision expanding gun rights, which has sparked a wave of legal challenges across the country.Since then, the court has upheld a law aimed at protecting victims of domestic violence and strict regulations on ghost gun kits, while banning bump stocks, an accessory that enables rapid fire. Judges have considered two firearms cases in this period alone.Cannabis laws have also evolved significantly in recent years, with over half of US states now legalizing marijuana in some form and its medical use becoming widespread.However, even after the Trump administration reclassified medical marijuana as a less dangerous drug in April, recreational use remains illegal under federal law.Standalone criminal charges involving firearm possession and drug use are relatively rare, and are often filed along with other crimes.The case gave rise to unusual political alliances. The American Civil Liberties Union and the National Rifle Association both endorsed Hemani, along with cannabis advocacy groups like NORML. On the opposing side were gun safety organizations such as Everytown, which generally disagreed with the Trump administration on Second Amendment issues.(with AP input)
