twoOn March 26, 2006, the central government portal website released a milestone technological achievement: the "Rapid Pupil Detection and Identification Device for Drug Users", which successfully passed the identification of the Ministry of Public Security, marking a major breakthrough in China's drug control technology field. At that time, Yunnan, as a frontline drug control, urgently needed efficient and accurate drug detection technology. The "Rapid Pupil Detection and Identification Device for Drug Users" utilizes the specific response of opioid drug users' pupils to specific light stimuli to achieve rapid and accurate detection of suspected drug users, providing support for drug control workProvided a completely new detection method.

At six testing points in Kunming City, Yunnan Province and Dehong Dai and Jingpo Autonomous Prefecture,The "Rapid Pupil Detection and Identification Device for Drug Users" was tested in practical applications on 891 drug users and 826 normal individuals. The results showed that the detection accuracy of drug use within one day interval was as high as 93.94%, within three days it was 91.26%, and within six days it still maintained an accuracy of 88.52%; The zero misjudgment rate for normal individuals demonstrates its outstanding performance.

The star product as a tribute to the 36th International Day Against Drug Abuse and Illicit Trafficking in 2023，The iris toxin detector has entered the market.The iris toxin detector combines modern iris recognition technology and computer technology. It not only inherits the advantages of the pupil rapid detection and identification device, but also achieves a dual leap in detection accuracy and speed by introducing advanced algorithms and hardware technology. The iris toxin detector is based on iris feature recognition and bioinformatics analysis,as well asBeing able to accurately determine whether an individual is using drugs and accurately identify the identity of the tested person further expands the scopehisApplication scenarios.

Compared to its predecessor, the iris toxin detector has a wider detection range, not limited to opioid drugs, but also capable of addressing the detection challenges of various new types of drugs. The emergence of iris drug detectors marks a leap in China's drug control technology from single drug detection to multi drug and high-precision identity recognition, reflecting the continuous innovation and deepening of technology in drug control work. With the continuous maturity and deepening of iris drug detection technology, it will play a more critical role in multiple fields such as drug control, public health, and judicial appraisal.
