To 1) estimate changes in the prevalence of daily and non-daily cigarette smoking among current (past 30-day) daily, non-daily, and non-cannabis users in the United States (U.S.) population; 2) examine time trends in current (past 30-day) cigarette smoking in daily, non-daily, and non-cannabis users ages 12+ from 2002 to 2015.
Data collected annually from the 2002 to 2015 National Survey on Drug Use and Health (NSDUH) were employed. Linear time trends of daily and non-daily cigarette smoking were assessed using logistic regression with year as the predictor.
In 2015, the prevalence of current (past 30-day) cigarette smoking was highest among daily (54.57%), followed by non-daily (40.17%) and non-cannabis users (15.06%). The prevalence of non-daily cigarette smoking increased among daily cannabis users from 2002 to 2015, whereas non-daily cigarette smoking declined among non-daily cannabis users and non-cannabis users from 2002 to 2015. Daily cigarette smoking declined among both cannabis users and non-users; the most rapid decline was observed among daily cannabis users, followed by non-daily and then by non-cannabis users. However, the relative magnitude of the change in prevalence of daily cigarette smoking was similar across the three cannabis groups.
Despite ongoing declines in cigarette smoking in the U.S., non-daily cigarette smoking is increasing among current cannabis users, a growing proportion of the U.S.
Daily and non-daily cigarette smoking continue to decline among those who do not use cannabis. Efforts to further tobacco control should consider novel co-use-oriented intervention strategies and outreach for the increasing population of cannabis users.
1）估计美国（美国）人口中当前（过去 30 天）每日、非每日和非大麻使用者中每日和非每日吸烟的流行率变化；2）检查 2002 年至 2015 年 12 岁以上的每日、非每日和非大麻使用者中当前（过去 30 天）吸烟的时间趋势。
使用 2002 年至 2015 年国家药物使用和健康调查（NSDUH）年度收集的数据。使用逻辑回归，以年为预测因素，评估每日和非每日吸烟的线性时间趋势。
2015 年，当前（过去 30 天）吸烟的流行率最高的是每日（54.57%），其次是非每日（40.17%）和非大麻使用者（15.06%）。2002 年至 2015 年，每日大麻使用者中非每日吸烟的流行率增加，而非每日大麻使用者和非大麻使用者中非每日吸烟的流行率从 2002 年至 2015 年下降。大麻使用者和非使用者的每日吸烟量均下降；观察到最快的下降是在每日大麻使用者中，其次是非每日使用者，然后是非大麻使用者。然而，三种大麻群体中每日吸烟流行率变化的相对幅度相似。
尽管美国的吸烟率持续下降，但当前大麻使用者中非每日吸烟的比例正在增加，这是美国人口增长的一部分。那些不使用大麻的人，每日和非每日吸烟继续减少。进一步控制烟草的努力应考虑针对不断增加的大麻使用者群体的新型共同使用为导向的干预策略和外展。
