A friend of mine was detained for taking drugs 15 days. He has a criminal record. Will the police check him when he checks in?

Those who have drug abuse records, ID card registration, accommodation or surfing the Internet will all enter the management scope of public security organs.

According to Article 3 of the Anti-drug Law of People's Republic of China (PRC), the public security organs of the people's governments at the county level are responsible for testing drug addicts, registering drug addicts and implementing dynamic management.
