Hong Kong Investment Immigration focuses on Life in Hong Kong: According to the Hong Kong Sing Tao Daily website, Zhang Jianliang, chairman of the Drug Treatment and Rehabilitation Subcommittee of the Hong Kong Action Committee Against Narcotics, stated that the recent increase in discreet drug use in Hong Kong is due to the transformation of drugs, which are highly concealable. Users may consume drugs for several years before serious mental health issues arise, making it difficult to detect discreet drug users early. He believes that community drug testing programs should balance social interests and personal privacy.

Regarding concerns that the program may lead to excessive police power, Zhang Jianliang suggested that police should adjust their sensitivity during enforcement, considering both environmental evidence and physical symptoms to balance social interests and personal privacy.
Zhang Jianliang also stated that the current transformation of drugs has shifted from highly addictive substances to those that are highly concealable. Even after a few days of abstinence, there are no withdrawal symptoms. Users may consume drugs for 4 to 5 years, with some even up to 8 years, before the effects on brain intelligence and emotions, such as schizophrenia, behavioral issues, and emotional instability, gradually become apparent, making it difficult to detect discreet drug users early.
Zhang Jianliang pointed out that although new drugs do not cause "addiction" symptoms, the psychological dependence they create can be as severe as that of heroin, requiring at least 9 months to detox. Currently, users primarily consume substances commonly known as ketamine, marijuana, and cocaine, with new cases of drug use reported each year. Among them, 70% continue to use drugs, leading to a continuous increase in the number of drug users.
