Compassion + Accountability = Recovery

King County Drug Diversion Court (KCDDC) is a voluntary program for adults who are charged with felony property and other drug-related crimes in King County.

KCDDC promotes community safety and empowers participants to rebuild their lives by addressing the root causes of criminal behavior.

KCDDC provides a daily structure and expectations that support recovery. Participants earn rewards to encourage positive life skills and are held accountable to program requirements through a range of court-ordered sanctions. KCDDC recognizes that recovery is a process and employs best practices and a dedicated, multidisciplinary team to support participants along the journey. Participants are required to attend treatment, provide frequent random urinalysis drug tests, and attend regular court hearings. Participants receive comprehensive support and resources to help them succeed – inpatient and outpatient treatment, medications, housing, transportation, peer support, vocational support, and family counseling if needed. The court and case managers provide supervision and monitoring to ensure participants stay on track and to recognize their progress and achievements.

KCDDC is a minimum 10-month program and requires participants meet specific milestones prior to graduation, in order to impart the tools and stability needed to prevent a return to substance use and criminal activity. When participants successfully complete the program, they graduate, resulting in a dismissal of their felony charge(s).

KCDDC is a proven effective program with data continuing to show significant reductions in 36-month recidivism, decreased homelessness, reduced substance use, and increased employment for all program participants (not just graduates).
