Much of our work involves measuring the difference others make. Getting involved and making our own difference is also an important part of who we are as individuals and as an organization.
The goal of the Marijuana Prevention Initiative (MPI) is to reduce youth marijuana use and increase knowledge of its negative impacts. To accomplish this goal the MPI collaborates with partners across San Diego County to bring awareness and education about: (1) local trends, (2) national research, (3) youth-related harms, and (4) public safety issues associated with marijuana use. This document provides selected county, state, and national data points regarding youth marijuana use and its related health and community impacts, organized by the four categorized referenced above. These data points provide relevant marijuana use/perception statistics to help inform marijuana prevention efforts currently underway across San Diego County. This report was made possible through funding from the County of San Diego, Health and Human Services Agency.

Can be hard to tell between packaging and look of products
By Gary Robbins
Food, candy and drinks infused with marijuana have become commonly available in California since January, when the first licensed pot stores began to open statewide.
The products are among the more popular items sold by the dispensaries. The consumption of edibles also is being popularized by cannabis cooking classes and free online tutorials.
