Since 1990, the eight jurisdictions in California, Texas, Kentucky, New York, Virginia, Oregon, Maryland, and Arizona have developed a variety of initiatives. Among the few components these various programs have in common are a police enforcement component, a focus on neighborhoods, and an emphasis on drug demand reduction. All eight INOP programs have either implemented or attempted to implement a broad array of partnerships with State and local agencies and community organizations within their respective jurisdictions. In many respects, however, differences among the eight initiatives are more striking than their commonalities. The INOP projects vary greatly in terms of the size of the locality in which they have developed and with respect to their historical relationship to other neighborhood or community-oriented policing initiatives. The INOP projects also differ substantially in terms of their approach to the drug demand reduction effort. In some jurisdictions, the primary emphasis is on drug enforcement, supplemented by secondary drug prevention activities. In other areas, more emphasis is placed on the provision of community-based services, including drug prevention, education, and treatment. Detailed descriptions of the eight INOP projects are provided, and a planned evaluation of the projects is noted. The descriptions include information on the target area, drug demand reduction activities, and expected impacts.
