Drug Addiction

Psychotropic Substance Abuse and Dependence

Psychotropic substance is a chemical substance that acts on the central nervous system and alters brain functioning. It consists of natural or synthetic products. Some psychotropic substances are produced naturally and adopted for medical use, such as cocaine, while some psychotropic substances are produced synthetically from chemicals without medical purpose, such as K2 and mephedrone.

The impacts of psychotropic substance abuse and dependence

Chemical substances can alter the user’s senses, cognition, perception, consciousness, mood and behavior. The user may pursue the enjoyment experienced from these alterations resulting in addiction. Some of the characteristics of substance abuse and dependence include intense craving, tolerance, withdrawal, continuous use despite negative consequences, impairments of health, social relationships and work performance. Moreover, supply, trafficking, possession and use of illegal psychotropic substances are strictly prohibited in Hong Kong.
