US applauds China's action on opioid - USA

US drug enforcement officials are praising China's ban of the opioid carfentanil, which is 10,000 times as potent as morphine and is sometimes used as a tranquilizer for elephants, and three related synthetic opioids. Yu Haibin, director of the Office of the National Narcotics Control Committee, told The Associated Press that China's ban showed its "attitude as a responsible big country" and that "it will be a strong deterrent".
