Sociodemographic and Cessation-related Differences between Tobacco-Marijuana Co-users and Single Product Users in a College Student Population Open Access
Masters, Matt (2017)
Abstract
Prevalence of tobacco-marijuana co-use has increased nationally. Many studies of tobacco and marijuana exist, but there is significantly less research available on the co-users of both substances, particularly regarding differences in correlates of cessation behaviors. This study is a secondary data analysis of the Project DECOY cohort of college students in Georgia and aims to address this research gap.
Among participants reporting any cigarette or marijuana use in the past 4 months, we conducted analyses to examine correlates (sociodemographics, mental health, substance use related factors) of 1) substance use group membership (cigarette-only, marijuana-only, and co-use), 2) readiness to quit each substance in the next month comparing single product users versus co-users, and 3) having made an attempt to quit each substance in the past four months comparing single product users versus co-users.
Results showed that alternative tobacco product use was associated with being a co-user. Most notably, e-cigarette and little cigar and cigarillo (LCC) use was associated with higher odds of being a co-user rather than cigarette-only user or marijuana-only user. E-cigarette use was associated with increased readiness to quit cigarettes and increased odds of a cigarette quit attempt. LCC use was associated with increased readiness to quit cigarettes and increased odds of a marijuana quit attempt. Technical and HBCU school students had increased odds of being ready to quit marijuana, while public and technical schools had increased odds of having a marijuana quit attempt. Interestingly, higher depression score was associated with increased odds of readiness to quit marijuana and marijuana quit attempts.
Associations between alternative tobacco products and cessation behavior are supported by previous research, but the association between increased depression score and marijuana quit attempts and readiness to quit marijuana is unexpected and should be further investigated. The use of alternative tobacco products such as e-cigarettes and LCCs in quitting should inform policy and intervention makers on college campuses, particularly considering the influence of school type on cessation behaviors. The results of this study can be used to better inform prevention and cessation efforts in the changing landscape of substance use.
