This just in! TMZ reports that marijuana was found when Rihanna‘s tour bus was pulled over by cops on the border of Michigan and Canada.

A total of 10 buses were stopped at the Ambassador Bridge, which separates Windsor, Canada and Detroit. Inspectors smelled marijuana on one of the buses and initiated a secondary, bus-to-bus search.

Inspectors then brought drug-sniffing dogs on board, and one of them made a beeline for a passenger and authorities found he was in possession of pot. We’re told he was cited with a civil penalty.

Rihanna was not on any of the buses pulled over, so it looks like her carrier is going to take the L on this one. Someone should have warned Rihanna about Canada’s stiff borders, especially since she takes no qualms with exposing the fact she likes to smoke that loud to the public via her social media accounts.
