Cannabis use is increasing in the United States, and, on average, those consuming medical cannabis report more frequent cannabis use than those who use recreationally. The present analyses focus on the prevalence and correlates of working under the influence of cannabis (WUIC) amongst individuals with chronic pain who use cannabis medically.
Adults were recruited from medical cannabis certification clinics in Michigan and individuals who were employed in the past 6 months were included in the analytic sample (N = 362). Unadjusted and adjusted logistic regressions were estimated to examine factors associated with WUIC. Descriptive analyses examined WUIC by types of employment.
WUIC was reported by 34% (n = 123) of employed medical cannabis patients. After adjusting for other factors, older age and having episodes of 6+ drinks were significantly associated with lower odds of WUIC. History of driving under the influence of cannabis, reporting three+ hours high on cannabis per day, and using 0.5 oz+ of cannabis per week were all significantly associated with higher odds of WUIC.
Amongst individuals who use cannabis for pain and are in the workforce, WUIC is relatively common. This may be particularly concerning in jobs that are safety-sensitive. Prevention efforts for WUIC might focus on those who use cannabis several times per day and might consider how to balance the needs for pain management with workplace-related roles.
The current study extends knowledge around the prevalence and characteristics of individuals using medical cannabis who engage in WUIC.
在美国，大麻的使用呈上升趋势，而且平均而言，使用医用大麻的人报告的大麻使用频率高于娱乐性使用者。本分析聚焦于医用大麻使用者中，在大麻影响下工作（WUIC）的患病率及其相关因素，这些使用者患有慢性疼痛。
从密歇根州的医用大麻认证诊所招募成年人，分析样本纳入过去6个月内有工作的个体（N = 362）。估计未调整和调整后的逻辑回归，以检验与WUIC相关的因素。描述性分析按就业类型检查WUIC情况。
34%（n = 12）的在职医用大麻患者报告有WUIC情况。在调整其他因素后，年龄较大以及有6杯及以上饮酒经历与较低的WUIC几率显著相关。有大麻影响下驾驶的历史、报告每天吸食大麻3小时以上以及每周使用0.5盎司及以上大麻均与较高的WUIC几率显著相关。
在因疼痛而使用大麻且有工作的人群中，WUIC相对常见。在对安全敏感的工作中，这可能尤其令人担忧。针对WUIC的预防措施可能应关注那些每天多次使用大麻的人，并可能需要考虑如何在疼痛管理需求与工作场所职责之间取得平衡。
本研究扩展了关于从事WUIC的医用大麻使用者的患病率和特征的知识。
