Compulsory detoxification is about 3000-5000 yuan, and voluntary detoxification is about 5000- 10000 yuan. Drug rehabilitation centers in China are divided into three categories: the first category is compulsory drug rehabilitation centers, which are in charge of public security departments; The second category is the rehabilitation center for reeducation through labor, which is in charge of the judicial department; The third category is drug rehabilitation medical institutions, which are headed by the health department. According to the regulations, compulsory detoxification was carried out in the drug rehabilitation center for the first time, and the relapsers entered the reeducation through labor. However, the reeducation-through-labor team also needs the government to set up and provide funds and manpower. Moreover, the number of drug addicts is large, which is simply overwhelming. Therefore, only a small part is actually accommodated. According to the Regulation on Drug Addiction, the state encourages drug addicts to give up drug addiction on their own. Drug addicts can go to drug rehabilitation medical institutions to receive drug rehabilitation treatment. The public security organs shall not punish drug addicts who voluntarily accept drug treatment. According to the Ministry of Health, it takes more than two months for voluntary detoxification to have a good withdrawal effect. The Ministry of Health has set a certain charge standard for drug rehabilitation, which will vary according to the degree of addiction, drugs used and physical condition of addicts.
