More than half of U.S. states legalized medical or recreational sale and possession of cannabis since the prevalence of cannabis use was last estimated among U.S. military veterans in 2014. To provide updated estimates of the prevalence and correlates of cannabis use, cannabis use disorder (CUD), and medical cannabis card possession in this population, data were analyzed from the 2019-2020 National Health and Resilience in Veterans Study, a nationally representative survey of 4,069 veterans ages 22-99 years who reported on their past-6-month cannabis use, CUD symptoms, and possession of a medical cannabis card. An estimated 11.9% [95% confidence interval (CI) = 10.9-12.9%)] of veterans reported using cannabis, 2.7% (95% CI = 2.3-3.3%) screened positive for CUD, and 1.5% (95% CI = 1.2-2.0%) reported possessing a medical card. Prevalence of cannabis use, CUD, and card possession were higher among younger veterans (use: 20.2%, CUD: 5.6%, card: 2.1%) and those with psychiatric conditions (use: 24.0%-30.0%, CUD: 8.9%-13.0%, card: 3.1%-4.0%). Younger age, alcohol use disorder, and childhood adversity explained a large proportion of variance in cannabis use and CUD, and depression was independently associated with CUD (odds ratio [OR] = 2.76). Physical disability (OR = 3.59), combat veteran status (OR = 2.84), and non-Hispanic black (OR = 0.23) relative to white race/ethnicity most strongly predicted using cannabis with a medical card. The estimated prevalence of cannabis use in veterans-nearly 12%-is higher than the most recently reported estimate (9% in 2014). Veteran cannabis use may be increasing and is particularly prevalent among veterans with psychiatric conditions.
自 2014 年最后一次估计美国退伍军人的大麻使用流行率以来，美国已有一半以上的州将医用或娱乐用大麻的销售和持有合法化。为了提供该人群中大麻使用、大麻使用障碍 (CUD) 和医用大麻卡持有率的最新估计，对 2019-2020 年全国退伍军人健康和复原力研究的数据进行了分析，这是一项对 4069 名年龄在 22-99 岁的退伍军人进行的全国代表性调查，他们报告了过去 6 个月的大麻使用、CUD 症状和医用大麻卡持有情况。估计有 11.9%（95%置信区间[CI] = 10.9-12.9%）的退伍军人报告使用大麻，2.7%（95%CI = 2.3-3.3%）筛查出 CUD，1.5%（95%CI = 1.2-2.0%）报告持有医用卡。年轻退伍军人（使用率：20.2%，CUD：5.6%，卡持有率：2.1%）和有精神疾病的退伍军人（使用率：24.0%-30.0%，CUD：8.9%-13.0%，卡持有率：3.1%-4.0%）的大麻使用、CUD 和卡持有率更高。年龄较小、酒精使用障碍和童年逆境在大麻使用和 CUD 中占很大比例，抑郁与 CUD 独立相关（优势比[OR] = 2.76）。身体残疾（OR = 3.59）、战斗退伍军人身份（OR = 2.84）和非西班牙裔黑人（OR = 0.23）与白种人种族/民族相比，最能预测使用医用大麻的情况。退伍军人中大麻使用率的估计值接近 12%，高于最近（2014 年）的报告值（9%）。退伍军人中可能越来越多地使用大麻，特别是在有精神疾病的退伍军人中更为普遍。
