Sumo: Russian wrestler expelled over marijuana by Patrice Novotny TOKYO, Aug 21, 2008 (AFP) – Japan’s sumo authority on Thursday expelled a Russian wrestler caught with marijuana, an unprecedented punishment which activists said highlighted the rigidity of the country’s drug laws. It was the latest in a raft of scandals for the 2,000-year-old sport, whose image was tainted last year when a teenage apprentice died after violent abuse by his stable.
