Control, Peer Association, and Permissive Attitudes to Drug Use: An Integrated Model Explaining Illicit Drug Use in China.

Since 2014, synthetic drugs have replaced opioids to become the most popular illicit drugs in China. Objectives: To explain illicit drug use in contemporary China, this research develops an integrative theoretical model including control theories, differential association theory, and normalization theory. Methods: The study draws on the first-hand data collected from 716 drug users in four compulsory drug detoxification institutions in China. Results: Low self-control increases drug use frequency through the heightened association with drug-use friends and more permissive attitudes to drug use simultaneously. However, family attachment indirectly influences drug use frequency via more permissive attitudes to drug use but not drug-use friends. Conclusion & contribution: The results show that the influence of self-control and family attachment is fully mediated by drug-use friends and permissive attitudes to drug use. This study provides a detailed picture of the mechanism of how self- and social control influence drug use frequency and contributes to the larger body of scholarship integrating criminological theories to understand drug use behaviors in China. The implications of the findings for scientific and effective drug treatment programs are also discussed.
