The San Diego County MPI works to reduce youth access to marijuana by increasing public awareness regarding the adverse effects resulting from youth marijuana use. We aim to decrease community acceptance and tolerance of marijuana use and access among youth living in San Diego County between the ages of 12-25. These years are crucial both academically and developmentally.

The MPI uses research-based strategies for all community interventions and ensures that efforts are SMART — Specific, Measurable, Attainable, Relevant, and Timely. The Initiative additionally supports regional capacity building through the SAMSHA Prevention Technology Transfer Center (PTTC) Region-9 as a Advisory Board Member.

“Joe Eberstein has provided MHS North Inland Community Prevention staff and many of our regional stakeholders with tremendous insight on the various applications and topics in support of the Marijuana Prevention Initiative projects we are working on...Joe helped us organize to raise public awareness of the dangers of driving under the influence of alcohol, marijuana or other drugs. He is incredibly well-informed, and instinctively intuitive. We are fortunate and privileged to have a trusted colleague like Joe and the MPI contributing to the AOD prevention successes we are realizing in the San Diego North Inland region.”
