Anti-drug authorities in Japan have arrested 6 people on suspicion of possessing a large supply of so-called "dangerous drugs." The drugs are mixtures of herbs and chemicals, similar to illegal narcotics.
The health ministry's anti-drug officials say 50-year-old Manabu Iwamura, and 5 others, were found in possession of 20 kilograms of the banned substances in September at a house in Kawasaki city, located south of Tokyo
