背景：过去一个月，美国成年人吸食大麻和烟草（共同使用）的情况有所增加，但人们对美国青少年共同吸食的流行情况知之甚少。本研究使用全国代表性的数据来评估美国青少年中大麻和烟草共同使用、仅使用烟草和仅使用大麻的流行率、相关性和趋势。方法：数据来自 176,245 名 12-17 岁的青少年，他们对 2005 年至 2014 年间的全国药物使用和健康调查进行了调查，这是一项具有全国代表性的家庭访谈调查。 2013 年至 14 月对三组进行了评估：过去一个月的大麻和烟草使用者（共同使用者）、过去一个月的纯烟草使用者和过去一个月的纯大麻使用者。使用多项逻辑回归来评估每组的人口统计学相关性。使用正交多项式的逻辑回归评估了 2005 年至 2014 年的线性和二次趋势。 结果：2013-14 年，5.4% 的青少年报告过去一个月同时使用烟草和大麻，2.2% 报告仅使用大麻，3.9% 报告仅使用烟草。共同使用与过去一年大麻依赖（相对于仅大麻使用者）的较高患病率以及过去一个月高风险酒精和其他非法药物使用（相对于烟草和仅大麻使用者）的较高相关。 2005 年至 2014 年间，共同使用并没有显着增加；只吸烟草的人减少了，只吸大麻的人增加了。结论：在美国青少年中，大麻和烟草的共同使用比只吸烟草或只吸大麻更为普遍。鉴于不断变化的烟草和大麻政策，旨在增加我们对青少年共同使用行为的理解的持续监测和研究至关重要。
Background: Past-month marijuana and tobacco use (co-use) are increasing among U.S. adults, but little is known about the prevalence of co-use among U.S. youth. This study uses nationally representative data to assess the prevalence, correlates, and trends in co-use of marijuana and tobacco, tobacco-only use, and marijuana-only use among U.S. youth.Methods: Data came from 176,245 youth ages 12-17 who responded to the National Survey on Drug Use and Health a nationally representative, household interview survey between 2005 and 2014. Prevalence, demographics and substance use characteristics from 2013 to 14 were assessed across three groups: past-month users of marijuana and tobacco (co-users), past-month tobacco-only users, and past-month marijuana-only users. Multinomial logistic regression was used to assess demographic correlates of each group. Linear and quadratic trends were assessed from 2005 to 2014 using logistic regression with orthogonal polynomials.Results: In 2013-14, 5.4% of youth reported past-month co-use of tobacco and marijuana, 2.2% reported marijuana-only use, and 3.9% reported tobacco-only use. Co-use was associated with higher prevalence of past year marijuana dependence (vs. marijuana-only users), and higher past-month risky alcohol and other illicit drug use (vs. both tobacco and marijuana-only use groups). Co-use did not increase significantly between 2005 and 2014; tobacco-only use declined, and marijuana-only use increased.Conclusions: Co-use of marijuana and tobacco is more prevalent than tobacco-only or marijuana-only use in U.S. youth. Given changing tobacco and marijuana policies, ongoing surveillance and studies that seek to increase our understanding of co-use behaviors in youth are critical.
