The proposed bill allows individuals charged with specific controlled substance-related offenses in Washington to seek dismissal of those charges if they complete a certified substance abuse treatment program. It establishes a new section in chapter 69.50 RCW, outlining the process for individuals to demonstrate their eligibility for dismissal. To qualify, individuals must provide proof of undergoing a certified assessment for substance use disorder and successfully completing a court-approved treatment program. The assessment must take into account the individual's criminal and substance use history, confirming the need for treatment.

If the individual submits the necessary documentation, including the assessment report and proof of treatment completion, the court is required to dismiss the charges without prejudice if it finds that the assessment supports the need for treatment, the individual has completed the program, and the interests of justice justify the dismissal. Additionally, the court has the discretion to dismiss related nonpossession charges unless the prosecutor objects. The court must document its reasons for the dismissal in writing and on the record.
