It’s no secret that Rihanna’s had a love affair with Mary Jane. She’s never hidden her affinity for weed, but in this case the singer wasn’t at fault. According to TMZ, officials discovered weed on one of the pop star’s tour buses.

A fleet of 10 tour buses was attempting to cross the border from Michigan to Canada on the Ambassador Bridge, when authorities smelled the aura of weed in one of the vehicles. The inspectors started a search, even bringing in dogs that specialize in detecting drugs.

After the dog pinpointed the culprit, that passenger was cited with a civil penalty. Rihanna wasn’t on the buses.
