What does it mean for community drug addicts to be called by the police station for a urine test for three months?

All drug addicts caught by the public security organs will be under strict supervision for a period of time. Most commonly, when they buy a train or plane ticket, open a hotel or surf the Internet in an Internet cafe, they will face a door-to-door investigation or urine test by the police to confirm whether they have committed drug abuse or drug-related crimes.

As we all know, although drug abuse is only illegal in China, it is easy for the whole drug addicts to turn from illegal to criminal. Therefore, in order to reduce the drug crime rate, as early as 2006, the Ministry of Public Security formulated the anti-drug measures-the dynamic control and early warning system for online drug addicts.

The specific operation is to input all the information of people with drug abuse history or drug-related crimes into the internal system, and then realize national information sharing, dynamic monitoring and online tracking through networking. This system is not only available in the national public security system, but also must be connected to the platform where public places need to use ID cards to register, so as to facilitate online inquiry and early warning. Dynamic control is actually to monitor people with a history of drug abuse for a period of time, usually three years. This is based on section 7 of the Drug Addiction Treatment Ordinance. "The personal information of drug addicts should be kept confidential according to law, and those who have not relapsed for three years will no longer be subject to dynamic control." But there is a premise here that abstinence for three years must be carried out under supervision, not that you can't be arrested for drug abuse again within three years. Therefore, some drug addicts can go to the local community for detoxification and report their urine tests regularly, usually once every two months in the first year, once every three months in the second year and once every three and a half years. After three years, he passed the community certification and applied to the local anti-drug department to eliminate dynamic control.
