Marijuana was found on one of Rihanna's tour buses as her touring party caravan tried to cross the border between Windsor, Canada and Detroit, M.I.

According to TMZ, 10 buses were stopped at the Ambassador Bridge when one of the inspectors smelled the drug's aroma.

Drug-sniffing dogs were brought on board and one particular passenger had pot on him. He was given a civil penalty, as it was a small amount.

Rihanna, however, was not present on any of the buses.

The singer's affinity for weed is well-documented, if not by journalists, then by herself.

Her Instagram account is typically littered with photos of the singer either smoking weed or making allusions to her preoccupation with smoking.
