In early February, the anti-narcotic unit of the Tokyo police was in the limelight after arresting Kazuhiro Kiyohara, a former star professional baseball player, on suspicion of unlawfully possessing stimulant drugs. But the case is just a tip of the iceberg as illegal drugs keep permeating through Japanese society with no end in sight.

A former anti-drug police officer has pointed to a lack of ability on the part of the authorities charged with controlling narcotics such as the police and the health ministry, saying, "Why did it take so long to arrest a guy like Kiyohara who had been heavily dependent on drugs?"

Indeed, it was in March 2014 that the weekly Shukan Bunshun magazine reported that Kiyohara, who had long been rumored to be using stimulant drugs since the 1990s, was rushed to a hospital after suffering drug poisoning.
