The purpose of this study was to determine whether the Lummi Nation's Community Mobilization Against Drugs (CMAD) Initiative successfully achieved its four stated goals, which were to reduce illicit drug trafficking, reduce rates of substance use disorder and addiction, prevent drug abuse and underage drinking among youth, and mobilize the community in all aspects of prevention, intervention, and suppression of alcohol and drug use, drug abuse, and drug trafficking. The study also aimed to evaluate whether the outcomes of the demonstration project had application for other tribal communities confronting similar public safety issues related to substance abuse. Qualitative information from focus group interviews was collected. Six focus groups were held with individuals representing the following populations: service providers, policy makers, adult clients and family members, youth, traditional tribal healers, and community members. In addition to the focus groups, the evaluation team conducted an interview session with two traditional providers who preferred this format. All focus groups were conducted on-site at Lummi by two trained moderators from the evaluation team. There were six different sets of questions, one for each group. Each set included 9 to 10 open-ended questions, which addressed knowledge and impact of the Community Mobilized Against Drugs (CMAD) Initiative; issues or problems with the Initiative; how the community viewed its actions; the importance and inclusion of a cultural perspective (traditional healers and others) in implementing various aspects of the CMAD Initiative; and how the Initiative had affected work and networking capabilities, policy making decisions, and/or treatment. Participants were also asked to think about what they would like CMAD to address and about their perceptions and definitions of some of the service barriers they may be experiencing (clients, community, and/or youth). All of the focus groups were openly audio taped with full knowledge and agreement of the participants.
