Objective:

The authors sought to estimate the prevalence of past-12-month and lifetime cannabis use and cannabis use disorder among U.S. veterans; to describe demographic, substance use disorder, and psychiatric disorder correlates of nonmedical cannabis use and cannabis use disorder; and to explore differences in cannabis use and cannabis use disorder prevalence among veterans in states with and without medical marijuana laws.

Methods:

Participants were 3,119 respondents in the 2012–2013 National Epidemiologic Survey on Alcohol and Related Conditions–III (NESARC-III) who identified as U.S. veterans. Weighted prevalences were calculated. Logistic regression analyses tested associations of nonmedical cannabis use and cannabis use disorder with demographic and clinical correlates and examined whether prevalence differed by state legalization status.

Results:

The prevalences of any past-12-month cannabis use and cannabis use disorder were 7.3% and 1.8%, respectively. Lifetime prevalences were 32.5% and 5.7%, respectively. Past-12-month and lifetime cannabis use disorder prevalence estimates among nonmedical cannabis users were 24.4% and 17.4%, respectively. Sociodemographic correlates of nonmedical cannabis use and use disorder included younger age, male gender, being unmarried, lower income, and residing in a state with medical marijuana laws. Nonmedical cannabis use and use disorder were associated with most psychiatric and substance use disorders examined.

Conclusions:

Among veterans, the odds of nonmedical cannabis use and use disorder were elevated among vulnerable subgroups, including those with lower income or psychiatric disorders and among survey participants residing in states with medical marijuana laws. The study findings highlight the need for clinical attention (e.g., screening, assessment) and ongoing monitoring among veterans in the context of increasing legalization of cannabis.

美国退伍军人中大麻使用和大麻使用障碍的流行率和相关性：全国酒精及相关疾病流行病学调查 (NESARC-III) 的结果

客观的：

作者试图估计美国退伍军人过去 12 个月和一生中大麻使用和大麻使用障碍的流行率；描述与非医疗大麻使用和大麻使用障碍相关的人口统计、物质使用障碍和精神障碍；并探讨在有和没有医用大麻法的州退伍军人中大麻使用和大麻使用障碍流行率的差异。

方法：

在 2012-2013 年全国酒精及相关疾病流行病学调查-III (NESARC-III) 中，参与者为 3,119 名被确定为美国退伍军人的受访者。计算加权患病率。逻辑回归分析测试了非医疗大麻使用和大麻使用障碍与人口统计学和临床​​相关性的关联，并检查了流行率是否因州合法化状态而异。

结果：

任何过去 12 个月的大麻使用和大麻使用障碍的流行率分别为 7.3% 和 1.8%。终生患病率分别为 32.5% 和 5.7%。非医用大麻使用者过去 12 个月和一生的大麻使用障碍患病率估计分别为 24.4% 和 17.4%。非医用大麻使用和使用障碍的社会人口统计学相关因素包括年龄较小、男性、未婚、收入较低以及居住在有医用大麻法的州。非医疗大麻使用和使用障碍与所检查的大多数精神和物质使用障碍有关。

结论：

在退伍军人中，非医疗大麻使用和使用障碍的几率在弱势群体中有所增加，包括收入较低或精神疾病的人以及居住在有医用大麻法的州的调查参与者。研究结果强调，在大麻日益合法化的背景下，需要对退伍军人进行临床关注（例如，筛查、评估）和持续监测。
