大麻与烟草的共同使用最近有所增加，特别是在年轻人中。我们进行了一项混合方法研究：（1）检查共同使用的原因;（2）制定一个量表，评估参与者在纵向队列研究中共同使用的原因，该研究涉及来自7所格鲁吉亚学院和大学的3，418名18-25岁的学生。2015年夏季，在46名当前（过去30天，n = 26）或终身（n = 20）大麻使用者中进行了基于电话的半结构化访谈。随后，制定了量表项目，并将其纳入第3波。报告过去4个月烟草和大麻使用的参与者（n = 328）完成了大麻-烟草共同使用的原因部分。根据定性数据，大麻-烟草共同使用的原因包括协同效应，一种触发或先于另一种使用，使用一种减少另一种使用，共同管理，社会背景和实验。调查子样本包括37.1%的吸烟者，30.4%的LCC，9.4%的无烟，23.7%的电子烟和30.4%的水烟。出现了四个子尺度因素：（1）工具性，表明协同效应;（2）替代性，表明使用一种产品来减少/放弃另一种产品;（3）社会背景，表明在不同的环境/社会情况下使用;（4）实验性，表明对两种产品进行实验，但没有具体的共同使用原因。这些分量表表现出不同的协会与烟草类型使用;尼古丁依赖;大麻和酒精的使用频率;烟草和大麻的使用动机，分别;烟草和大麻的看法;和父母和朋友使用。在预测尼古丁依赖和大麻使用天数的回归中包括这些分量表对每个模型都有显着的贡献。这些发现可能会为大麻烟草共同使用的理论框架提供信息，并指导未来的干预研究。
Marijuana-tobacco co-use has increased recently, particularly in young adults. We conducted a mixed-methods study to: (1) examine reasons for co-use; and (2) develop a scale assessing reasons for co-use among participants in a longitudinal cohort study of 3,418 students aged 18-25 from 7 Georgia colleges and universities. Phone-based semi-structured interviews were conducted in Summer 2015 among 46 current (past 30-day, n = 26) or lifetime (n = 20) marijuana users. Subsequently, scale items were developed and included at Wave 3. Participants reporting past 4-month tobacco and marijuana use (n = 328) completed the Reasons for Marijuana-Tobacco Co-use section. Per qualitative data, reasons for marijuana-tobacco co-use included synergistic effects, one triggering or preceding the other’s use, using one to reduce the other’s use, co-administration, social context, and experimentation. The survey subsample included 37.1% who used cigarettes, 30.4% LCCs, 9.4% smokeless, 23.7% e-cigarettes, and 30.4% hookah. Four subscale factors emerged: (1) Instrumentality, indicating synergistic effects; (2) Displacement, indicating using one product to reduce/quit the other; (3) Social context, indicating use in different settings/social situations; and (4) Experimentation, indicating experimentation with both but no specific reasons for co-use. These subscales demonstrated distinct associations with tobacco type used; nicotine dependence; marijuana and alcohol use frequency; tobacco and marijuana use motives, respectively; perceptions of tobacco and marijuana; and parental and friend use. Including these subscales in regressions predicting nicotine dependence and days of marijuana use significantly contributed to each model. These findings might inform theoretical frameworks upon which marijuana-tobacco co-use occurs and direct future intervention studies.
