However, this method must obtain the normal pupil size of the suspect in the non-drug state in advance
When the grassroots police are dispatched to carry out anti-drug operations, they do not have the conditions to obtain the normal pupil size of the suspect who is not taking drugs. Therefore, it is difficult to use this method on the suspect who is checked for the first time during the anti-drug operation.
Moreover, although the patent pointed out that the method can also obtain the data of pupil dynamic changes before and after light stimulation, it did not clearly point out the method and measurement standard for screening drug addicts by using the pupil dynamic changes before and after light stimulation

Embodiment
[0025]Number the drug addict as the subject to be tested, and make the subject wear the brain electrode cap with the above-mentioned EEG collection part, so as to stick the scalp electrodes of the multi-conductor EEG instrument with scalp electrodes on the head, and the subject to be tested The light in both eyes was cut off. After adapting to the dark environment for half a minute, a uniform white light was given for 2 seconds, and then the light was removed and maintained for 2 seconds. The subjects were to keep their eyes closed or open during a complete test according to the requirements of the testers. The interval between eye closing and eye opening is repeated three times respectively, and the detection ends. The collected signal is displayed on the terminal display screen after being calculated by the computer connected with the light source and the polyconductor electroencephalogram. At the same time, the urine of the subjects was collected, and the actual morphine c...

The invention discloses a method for quickly screening out drug addicts by electroencephalogram characteristics. An electroencephalogram detection technology is utilized, and suspects who take drugs can be quickly screened out according to the electroencephalogram characteristics of reaction on illumination and light removal of people which are detected. The detection method for quickly screening out the drug addicts has the advantages of convenience in operation, high speed and accuracy in obtaining results and good accuracy and practicality.
Description
technical field [0001] The invention relates to a detection method for quickly screening drug addicts according to the electroencephalogram characteristics of the detected person. Background technique [0002] Rapid screening of drug suspects is one of the important contents of social anti-drug work. At present, the screening of drug suspects in my country is mainly based on the results of biochemical analysis of the tested person's urine or blood. Traditional urine test strips are easy to use and highly targeted, but they are expensive, have a short shelf life, cannot detect multiple (more than two) drugs, are not environmentally friendly, and are easily disturbed by diet and drugs. The problem. When extracting the tested body fluid sample, urine sample or blood sample, the accuracy of the operation is high, and technical personnel need to be specially trained. Moreover, due to the high proportion of drug addicts carrying various viruses, the chances of grassroots police...
