Detroit — Michigan’s marijuana laws are more mellow than they used to be, but a Canadian trash hauler allegedly pushed the envelope a bit Friday when U.S. Customs and Border Protection officers said they found 418 pounds of pot in a truck.

The truck was flagged for inspection around 4 a.m. after crossing into the United States on the Ambassador Bridge. An X-ray detected several odd shapes in the rear of the hauler, and an examination by border protection officers allegedly turned up 15 large trash bags full of pot.
