Abstract

A standardized national drug laboratory system has been constructed within the narcotics control framework of China's Ministry of Public Security. Centered on the Drug Intelligence and Forensic Center, Ministry of Public Security and supported by five regional branch narcotics laboratories, this platform is responsible for nationwide drug situation monitoring and early warning, forensic identification of drug-related cases, abuse risk assessment of new psychoactive substances (NPS), narcotics control technology innovation, serving as the fundamental technical guarantee for national scientific drug control. A complete technical system for NPS abuse risk assessment has been established relying on the national laboratory platform. Focusing on two core evaluation indicators including NPS addiction potential and harmful effects, this system adopts dual standardized evaluation approaches: in vitro screening and in vivo functional assessment. It forms a normalized and operable assessment paradigm that supports accurate addiction and harm identification and hierarchical risk classification of various emerging NPS. Long-term basic research and frontier practical verification have yielded abundant academic achievements and typical application cases. Continuous technological breakthroughs further optimize the practicability and accuracy of the assessment system. This framework has promising application and dissemination value, and provides effective technical references from China for global NPS risk management and addiction prevention.
