The man told police he had legally purchased marijuana at a dispensary in Boston, Mass., and brought it with him while visiting the Falls.

Around 3:15 p.m. Sunday, he told police he accidentally took a wrong turn onto the bridge heading toward Niagara Falls, Ont. After being turned back by Canadian officials, his vehicle was searched by U.S. border agents and about 1½ ounces of marijuana were found in the trunk, according to the police report.
