Conservative Supreme Court justice admits federal marijuana laws are outdated

Conservative Supreme Court Justice Clarence Thomas said that the federal government's marijuana policies are no longer up-to-date due to state legalisation efforts.

"A prohibition on interstate use or cultivation of marijuana may no longer be necessary or proper to support the federal government's piecemeal approach," he said on Monday.

NBC News reports that his statement was made as the court rejected a request to hear an appeal made by a Colorado medical marijuana dispensary that was denied federal tax breaks given to other businesses.
