Abstract

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.

摘要

本研究旨在探讨在加拿大蒙特利尔进行的一项注射吸毒者队列研究中，经常和偶尔使用大麻的人群在单次注射日使用大麻与共用针具之间的关系是否相似。236 名（36.6%）被归类为经常使用大麻者（RCUs），227 名（35.2%）为偶尔使用大麻者（NRCUs），181 名（28.1%）为不使用者。与 RCUs 相比，NRCUs 在单次注射日使用大麻与共享针具的风险增加五倍相关（OR 4.92；1.83-13.22）。我们的结果表明，在评估大麻对冒险行为的潜在影响时，应考虑大麻使用史。
