To report nationally representative findings on the prevalence, correlates, psychiatric comorbidity and treatment of DSM-IV Cannabis Use and Cannabis Use Disorders in Australia.
The 2007 National Survey of Mental Health and Wellbeing was a nationally representative household survey of 8841 Australians (16-85 years) that assessed symptoms of the most prevalent DSM-IV mental disorders.
Prevalence of lifetime and 12-month cannabis use was 18% and 6%; prevalence of lifetime and 12-month cannabis use disorder was 6% and 1%. The conditional prevalence (proportion of ever users who met criteria for a disorder) of lifetime and 12-month cannabis use disorder was 32.2% and 14.3%. Current cannabis use disorders were more common in males (OR 2.0) and younger users (OR 4.6). Strong associations were observed between current cannabis use disorders and alcohol use disorders (OR 3.6) and current affective disorders (OR 3.0). Only 36.2% of those with current cannabis use disorders sought any treatment.
The prevalence of cannabis use disorders in the Australian population is comparable with that in the USA. Current cannabis use disorders are highly concentrated in young Australians who have high levels of comorbidity. The low rates of treatment seeking warrant attention in treatment and prevention strategies.
报告澳大利亚 DSM-IV 大麻使用和大麻使用障碍的流行率、相关性、精神共病和治疗的全国代表性发现。
2007 年全国精神健康和幸福感调查是一项对 8841 名澳大利亚人（16-85 岁）进行的全国代表性家庭调查，评估了最常见的 DSM-IV 精神障碍的症状。
终身和 12 个月大麻使用的流行率分别为 18%和 6%；终身和 12 个月大麻使用障碍的流行率分别为 6%和 1%。终身和 12 个月大麻使用障碍的条件流行率（曾使用者中符合障碍标准的比例）分别为 32.2%和 14.3%。目前的大麻使用障碍在男性（OR 2.0）和年轻使用者（OR 4.6）中更为常见。目前的大麻使用障碍与酒精使用障碍（OR 3.6）和当前情感障碍（OR 3.0）之间存在强烈关联。只有 36.2%的当前大麻使用障碍患者寻求任何治疗。
澳大利亚人口中大麻使用障碍的流行率与美国相当。目前的大麻使用障碍高度集中在患有高度共病的年轻澳大利亚人身上。寻求治疗的低比率需要在治疗和预防策略中引起重视。
