Marijuana is the most commonly used drug across all groups. A greater understanding of risk factors associated with recent use can inform health prevention messaging and behavioral interventions. Pooled data from the 2015–2018 National Survey on Drug Use and Health were utilized among 89,446 individuals ages 18–34. Weighted logistic regression analyses, controlling for covariates, were utilized to determine conditional associations to past-30-day use. A sizeable percentage (18.5%) of individuals reported smoking marijuana in the past 30 days. Individuals who identify as African American or multi-racial, gay/lesbian, bisexual, reported their health as poor, not covered by health insurance, reported prior drug use, or who had reported any thoughts/plans of suicide were at risk for use. Of concern, high rates of alcohol (14.7%) and cocaine (1.50%) were found among users. We believe our findings can inform harm reduction efforts and policy creation.

大麻是所有群体中最常用的药物。更好地了解与最近使用相关的风险因素可以为健康预防信息和行为干预提供信息。来自 2015-2018 年全国毒品使用和健康调查的汇总数据在 89,446 名 18-34 岁的人中使用。控制协变量的加权逻辑回归分析被用来确定与过去 30 天使用的条件关联。相当大比例 (18.5%) 的人报告说在过去 30 天内吸过大麻。认定为非裔美国人或多种族、男同性恋/女同性恋、双性恋、报告其健康状况不佳、未参加健康保险、报告以前吸毒或报告有任何自杀想法/计划的个人有使用的风险。令人担忧的是，酒精 (14.7%) 和可卡因 (1. 50%) 是在用户中发现的。我们相信我们的发现可以为减少危害的努力和政策制定提供信息。
