The invention discloses a drug addict screening method based on pulse waves. The screening method comprises the steps that 1, a pulse wave collection device is adopted for collecting pulse waves of anaddict to be detected first; 2, pulse wave parameters are obtained by processing the pulse waves, and a characteristic variability pattern of the addict to be detected is obtained, and the characteristic variability pattern of the pulse waves is calculated, wherein the pulse wave parameters comprise total pulse wave pulse period time and pulse wave conduction time parameters; 3, judgment is conducted by using a big data model based on the parameters. The drug addict screening method based on the pulse waves lowers the detection cost, simplifies the detection process of drug addicts, shortensthe detection time of the drug addicts and improves the detection successful rate of the drug addicts.
