BACKGROUND: A growing number of states have new legislation extending prior legalization of medical marijuana by allowing nonmedical marijuana use for adults. The potential influence of this change in legislation on adolescent marijuana and other substance use (e.g., spillover or substitution effects) is uncertain. We capitalize on an ongoing study to explore the prevalence of marijuana and other substance use in 2 cohorts of adolescents who experienced the nonmedical marijuana law change in Washington State at different ages.

METHODS: Participants were 8th graders enrolled in targeted Tacoma, Washington public schools and recruited in 2 consecutive annual cohorts. The analysis sample was 238 students who completed a baseline survey in the 8th grade and a follow-up survey after the 9th grade. Between the 2 assessments, the second cohort experienced the Washington State nonmedical marijuana law change, whereas the first cohort did not. Self-report survey data on lifetime and past-month marijuana, cigarette, and alcohol use were collected.

RESULTS: Multivariate multilevel modeling showed that cohort differences in the likelihood of marijuana use were significantly different from those for cigarette and alcohol use at follow-up (adjusting for baseline substance initiation). Marijuana use was higher for the second cohort than the first cohort, but this difference was not statistically significant. Rates of cigarette and alcohol use were slightly lower in the second cohort than in the first cohort.

CONCLUSIONS: This exploratory study found that marijuana use was more prevalent among teens shortly after the transition from medical marijuana legalization only to medical and nonmedical marijuana legalization, although the difference between cohorts was not statistically significant. The findings also provided some evidence of substitution effects. The analytic technique used here may be useful for examining potential long-term effects of nonmedical marijuana laws on adolescent marijuana use and substitution or spillover effects in future studies.

BACKGROUND: In November 2012, Washington State and Colorado became the first states in the United States to legalize recreational marijuana use for adults, and Uruguay became the first country to allow the cultivation, distribution, possession, and use of marijuana. One possible consequence of these changes is increased adolescent marijuana use. Parents may mitigate this adverse consequence; however, whether parents and adolescents have accurate knowledge about the laws and are discussing marijuana use in light of the law changes is unknown.

OBJECTIVE: We examine perceptions, knowledge, and parent-child discussions about Washington State's recreational marijuana law in a sample of low-income families.

METHODS: Participants were a subset of families (n = 115) in an ongoing study that originally recruited parents and adolescents from middle schools in Tacoma, Washington. In summer 2013, when students were entering the 11(th) grade, students and their parents were asked questions about the recreational marijuana law.

RESULTS: Participants perceived that their marijuana-related attitudes and behaviors changed little as a result of the law, and displayed uncertainty about what is legal and illegal. Most parents reported discussing the new law with their children but only occasionally, and conversations emphasized household rules, particularly among parent lifetime marijuana users compared to non-users. Conclusions/Importance: Results suggest that there should be a public health campaign focused on families that provides clear information about the recreational marijuana laws.

This paper describes the extent to which communities implementing the Communities That Care (CTC) prevention system adopt, replicate with fidelity, and sustain programs shown to be effective in reducing adolescent drug use, delinquency, and other problem behaviors. Data were collected from directors of community-based agencies and coalitions, school principals, service providers, and teachers, all of whom participated in a randomized, controlled evaluation of CTC in 24 communities. The results indicated significantly increased use and sustainability of tested, effective prevention programs in the 12 CTC intervention communities compared to the 12 control communities, during the active phase of the research project when training, technical assistance, and funding were provided to intervention sites, and 2 years following provision of such resources. At both time points, intervention communities also delivered prevention services to a significantly greater number of children and parents. The quality of implementation was high in both conditions, with only one significant difference: CTC sites were significantly more likely than control sites to monitor the quality of implementation during the sustainability phase of the project.

This paper describes findings from the Community Youth Development Study (CYDS), a randomized controlled trial of the Communities That Care (CTC) prevention system, on the adoption and implementation fidelity of science-based prevention programming in 24 communities. Data were collected using the Community Resource Documentation (CRD), which entailed a multi-tiered sampling process and phone and web-based surveys with directors of community-based agencies and coalitions, school principals, service providers, and teachers. Four years after the initiation of the CTC prevention system, the results indicated increased use of tested, effective prevention programs in the 12 CTC intervention communities compared to the 12 control communities, and significant differences favoring the intervention communities in the numbers of children and families participating in these programs. Few significant differences were found regarding implementation quality; respondents from both intervention and control communities reported high rates of implementation fidelity across the services provided.
