Cannabis use correlates of syringe sharing among injection drug users.
This study examines whether the relation between acute cannabis use and syringe sharing during single injection days is similar among regular and nonregular users, participating in a cohort study of injection drug users in Montréal, Canada. 236 (36.6%) subjects were classified as regular cannabis users (RCUs), 227 (35.2%) as nonregular cannabis users (NRCUs), and 181 (28.1%) were abstinent. Cannabis use during a single injection day was associated with a fivefold increased risk of sharing (OR 4.92; 1.83-13.22) in NRCUs compared to RCUs. Our results indicate that cannabis use history should be considered when evaluating its potential effect on risk-taking behaviors.
