本研究针对癌症幸存者相对于没有癌症史的个体，确定与最近吸食大麻和医疗用途大麻使用有关的因素。数据来自2020年在22个州中完成自愿参加麻类模块的行为风险因素监测系统。进行了加权多元逻辑回归，以探索与过去30天大麻使用和医疗用途大麻使用有关的变量，按癌症史分层。协变量包括州级大麻政策、社会人口学特征、健康状态指标和物质使用。相对于没有癌症史的个体，癌症幸存者的大麻使用率较低（7.57％ vs. 10.83％）但更高比例的癌症幸存者报告了医疗用途的使用（82.23％ vs. 62.58％）。在调整州级政策、生物性别、年龄、教育程度、自报种族/民族、房屋所有权、心理健康状况和身体健康状况、吸烟（比率比[OR]，5.14 vs. 3.74）和酗酒（OR，2.71 vs. 2.69）后，两组人群中均与大麻使用有关。与医疗用途大麻使用相关的特征因组别而异；然而，在模型中调整其他变量后，每天使用（20-30天；OR，1.72 vs. 2.43）与两组中的医疗用途大麻使用有关。大量个体报告使用医疗用途大麻，癌症幸存者比例更高。研究结果支持继续进行大麻研究以更好地理解和告知其医疗用途的使用，以及制定高质量标准化教育资料和临床实践指南的迫切需要。 © 2023 The Authors.

This study identified factors associated with recent cannabis use and cannabis use for medical purposes among cancer survivors relative to individuals without a history of cancer.Data from the Behavioral Risk Factor Surveillance System were analyzed for the 22 states completing the optional cannabis module in 2020. Weighted multiple logistic regression was performed to explore variables associated with past 30-day cannabis use and cannabis use for medical purposes, stratified by history of cancer. Covariates included state-level cannabis policy, sociodemographic characteristics, health status indicators, and substance use.Cannabis use was lower among cancer survivors compared to individuals with no history of cancer (7.57% vs. 10.83%). However, a higher proportion of cancer survivors reported use for medical purposes (82.23% vs. 62.58%). After adjusting for state-level policy, biological sex, age, educational attainment, self-reported race/ethnicity, home ownership, mental health status and physical health status, current smoking (odds ratio [OR], 5.14 vs. 3.74) and binge drinking (OR, 2.71 vs. 2.69) were associated with cannabis use in both groups. Characteristics associated with medical cannabis use varied for the two groups; however, daily use (20-30 days; OR, 1.72 vs. 2.43) was associated with cannabis use for medical purposes in both groups after adjusting for other variables in the model.A high proportion of individuals report cannabis use for medical purposes with higher rates among cancer survivors. Findings support the urgent need for ongoing cannabis research to better understand and inform its use for medical purposes, as well as the development of high-quality standardized education materials and clinical practice guidelines.© 2023 The Authors.
