The natural history of injecting drug use among IDU in Melbourne: A prospective cohort study

我们对注射甲基苯丙胺流行病的反应受到阻碍，因为我们对注射毒品使用（IDU）的自然历史缺乏了解，这使用户面临伤害风险和干预措施的有效性。本研究将探讨典型的静脉吸毒者的行为轨迹，并提供一个服务评估的框架。这项研究将侧重于未经治疗的甲基苯丙胺和海洛因使用者，首次明确表明与这些不同类型的注射吸毒者有关的比较危害。

Our response to the emergent epidemic of methamphetamine injection is hampered by our lack of understanding of injecting drug use (IDU) natural history that place users at risk of harm and the effectiveness of interventions. This study will examine typical trajectories of IDU and provide a framework for service evaluation. The study will focus on untreated methamphetamine and heroin users, providing the first clear indication of the comparative harms associated with these different types of IDU.
