The Supreme Court has ruled that a federal law automatically banning unlawful drug users from possessing firearms is unconstitutional, dealing a major blow to the government's efforts to disarm individuals over routine drug use.

In a decision delivered by Justice Neil Gorsuch, the high court found that the government's prosecution of Ali Danial Hemani, who admitted to owning a gun while using marijuana a few times a week, violates the Second Amendment.

Ali Hemani is a dual citizen of the United States and Pakistan who was born in Texas and has spent most of his life in the Dallas area.
