Drug trafficking and abuse are illegal in China. Offenders may be sentenced to prison if smuggling 10 grams or more of heroin and could receive the death penalty for smuggling more than 50 gram of heroin. In 1990, the "Regulations on Prohibition Against Narcotics" were enacted with three levels of penalty to be applied to drug users. First-time offenders may be fined and/or allowed to go to voluntary detoxification centers, where they receive 10-day methadone treatment managed by the Ministry of Public Health. The cost of treatment is about 2,000 to 5,000 Chinese yuan -a cost considered expensive for many drug users and their families. If drug users who have gone through a voluntary detoxification program are caught again using drugs, they are sent to compulsory rehabilitation centers (CRC) administered by the Ministry of Public Security for 6 to 12 months. Drug users who relapse users after going through CRC are sent to reeducation-through-labor-centers (RELC) administered by the Justice Department for two to three years [33].
