Limited research has examined psychosocial factors that differ among cigarette users, marijuana users, and co-users and influence their cessation efforts. We examined: 1) sociodemographic, mental health, and other substance use in relation to user category; and 2) associations among these factors in relation to recent quit attempts and readiness to quit among single product versus co-users. We used a cross-sectional design to study college students aged 18-25 from seven Georgia campuses, focusing on the 721 reporting cigarette and/or marijuana use in the past 4months (238 cigarette-only; 331 marijuana-only; 152 co-users). Multinomial logistic regression showed that correlates (p's<0.05) of cigarette-only versus co-use included attending public or technical colleges (vs. private) and not using little cigars/cigarillos (LCCs), e-cigarettes, and alcohol. Correlates of marijuana-only versus co-use included being Black or Hispanic (vs. White), not attending technical school, and not using LCCs and e-cigarettes. Importance was rated higher for quitting cigarettes versus marijuana, but confidence was rated lower for quitting cigarettes versus marijuana (p's<0.001). Co-users were more likely to report readiness to quit and quit attempts of cigarettes versus marijuana (p's<0.001). While 23.26% of marijuana-only and 15.13% of cigarette-only users reported readiness to quit, 41.18% of cigarette-only and 21.75% of marijuana-only users reported recent quit attempts (p's<0.001). Binary logistic regressions indicated distinct correlates of readiness to quit and quit attempts of cigarettes and marijuana. Cessation efforts of the respective products must attend to co-use with the other product to better understand relative perceptions of importance and confidence in quitting and actual cessation efforts.
有限的研究考察了在吸烟、吸大麻和同时使用这两种物质的人群中存在差异的社会心理因素，以及这些因素如何影响他们的戒烟努力。我们研究了：1）与用户类别相关的社会人口统计学、心理健康和其他物质使用情况；2）这些因素之间的关联，以及它们与单产品使用者和同时使用者最近戒烟尝试和戒烟准备的关联。我们使用横断面设计研究了来自佐治亚州七个校区的 18-25 岁的大学生，重点关注在过去 4 个月内报告使用过香烟和/或大麻的 721 名学生（238 名仅使用香烟；331 名仅使用大麻；152 名同时使用者）。多项逻辑回归显示，与仅使用香烟相比，同时使用者的相关因素（p 值<0.05）包括就读于公立或技术学院（而非私立学院），不使用小雪茄/雪茄烟、电子烟和酒精。与仅使用大麻相比，同时使用者的相关因素包括为黑人或西班牙裔（而非白人），不就读于技术学校，以及不使用小雪茄/雪茄烟和电子烟。与戒烟大麻相比，戒烟香烟的重要性评分更高，但戒烟香烟的信心评分更低（p 值<0.001）。与戒烟大麻相比，同时使用者更有可能报告准备戒烟和尝试戒烟香烟（p 值<0.001）。虽然仅使用大麻的人中 23.26%和仅使用香烟的人中 15.13%报告准备戒烟，但仅使用香烟的人中 41.18%和仅使用大麻的人中 21.75%报告最近有戒烟尝试（p 值<0.001）。二元逻辑回归表明，准备戒烟和戒烟尝试的香烟和大麻的相关因素是不同的。针对相应产品的戒烟努力必须考虑到与另一种产品的同时使用，以便更好地理解对戒烟的重要性和信心的相对看法以及实际的戒烟努力。
