The mission of the King County Adult Drug Diversion Court (KCDDC) program is to combine the resources of the criminal justice system, drug and alcohol treatment and other community service providers to compel the substance-abusing offender to address his or her substance abuse problem by providing an opportunity for treatment and holding the offender strictly accountable.

KCDDC 20 Yr Anniversary

KC Councilmember Larry Gossett


King County Councilmember Larry Gossett shared words of appreciation for the program and the life-changing difference it makes for so many.

Program Description

KCDDC program was implemented in August 1994, the twelfth drug court in the country. KCDDC is a pre-adjudication program that provides eligible defendants the opportunity to receive drug treatment in lieu of incarceration. Eligible defendants can elect to participate in the program or proceed with traditional court processing. After choosing to participate in the KCDDC program, defendants come under the court's supervision and are required to attend treatment sessions, undergo random urinalysis, and appear before the KCDDC judge on a regular basis.

If defendants meet the requirements of each of the four phases of the KCDDC program they graduate from the program and the charges are dismissed. If defendants fail to make progress they are terminated from the program and sentenced on their original charge. While KCDDC is a minimum 12 month program, the average graduate requires 18 months to complete. KCDDC provides treatment to an estimated 320 individuals at any one time.
