Objective To understand the behavioral characteristics of common injection equipment among intravenous drug users in Liangshan Yi Autonomous Prefecture. Methods Based on community-based surveys of demographics and sharing of drug use among injecting drug users. As a result, of the 379 intravenous drug users, 247 (65.2%) had ever used common syringes and 16 6 (438%) used nearly 3 months of syringes used by other people. The average time taken for IV injection to change to sharing syringes with others was 36 3 73 days, of which 87 (35 2%) shared their first injection with other injecting devices for the first time. The number of drug addicts in Yi has shifted from their intravenous drug use to that of sharing syringes with others, the number of times drug users share syringes with other people, and the number of drug users who have used syringes in the past 3 months is higher than those of other drug users. The number of drug users with low educational level changed from their own intravenous drug users to those who shared the same drug with others for taking drugs for a long time, the number of drug users sharing other injecting devices, and the number of drug users who used other injecting devices in the past 3 months were higher than those of other drug users crowd. Conclusions Interventions are being conducted among Yi and low-drug-addicted drug users to change the high-risk behaviors of intravenous drug use in shared syringes.
