Public Perceptions and Attitudes Toward Adolescent Marijuana Use

Abstract

The purpose of the current study is to examine patterns in public perceptions and attitudes toward marijuana use among adolescents. Computer-assisted telephone interviewing (CATI) was used to collect data from a statewide sample of adults in Michigan identified through random-digit dialing ( n = 560). CATI interviews were supplemented with web- and paper-based surveys for nonrespondents. We used latent class analysis to characterize patterns in public perception, using a vignette technique that assessed (a) whether adults recognize adolescent marijuana use as a problem, (b) how they view the efficacy of treatment, (c) how they view help-seeking with mental health professionals, and (d) whether they support prevention services for adolescents. Multinomial logistic regression was used to examine the relationship between class membership and demographics, substance use, and methodological factors. Three latent classes were identified: (a) a discriminating group, (b) a low-concern group, and (c) a high-concern group. Age and substance use were among the strongest determinants for membership in the discriminating group. Results provide insight into how the general public perceives marijuana use and marijuana-related problems among adolescents.
