Cal. Penal Code § 1463.13

(a) Each county may develop, implement, operate, and administer an alcohol and drug problem assessment program for persons convicted of a crime in which the court finds that alcohol or substance abuse was substantially involved in the commission of the crime. This program may be operated in coordination with the program developed under Article 6 (commencing with Section 23645) of Chapter 4 of Division 11.5 of the Vehicle Code.
1. (1) A portion of any program established pursuant to this section shall include a face-to-face interview with each program participant.
2. (2) No person convicted of driving under the influence of alcohol or a controlled substance or a related offense shall participate in any program established pursuant to this section.
(b) An alcohol and drug problem assessment report shall be made on each person who participates in the program. The report may be used to determine the appropriate sentence for the person. The report shall be submitted to the court within 14 days of the completion of the assessment.
(c) In any county in which the county operates an alcohol and drug problem assessment program under this section, a court may order any person convicted of a crime that involved the use of drugs or alcohol, including any person who is found to have been under the influence of drugs or alcohol during the commission of the crime, to participate in the assessment program.
(d) Notwithstanding any other provision of law, in addition to any other fine or penalty assessment, there shall be levied an assessment of not more than one hundred fifty dollars ($150) upon every fine, penalty, or forfeiture imposed and collected by the courts for a public offense wherein the court orders the offender to participate in a county alcohol and drug problem assessment program. The assessment shall only be levied in a county upon the adoption of a resolution by the board of supervisors of the county making that county subject to this section.
(e) The court shall determine if the defendant has the ability to pay the assessment. If the court determines that the defendant has the ability to pay the assessment then the court may set the amount to be reimbursed and order the defendant to pay that sum to the county in the manner which the court determines is reasonable and compatible with the defendant’s financial ability. In making a determination of whether a defendant has the ability to pay, the court shall take into account the amount of any fine imposed upon the defendant and any amount the defendant has been ordered to pay in victim restitution.
(f) Notwithstanding Section 1463 or 1464 of the Penal Code or any other provision of law, all moneys collected pursuant to this section shall be deposited in a special account in the county treasury and shall be used exclusively to pay for the costs of developing, implementing, operating, maintaining, and evaluating alcohol and drug problem assessment and monitoring programs.
(g) On January 15 of each year, the treasurer of each county that administers an alcohol and drug problem assessment and monitoring program shall determine those moneys in the special account which were not expended during the preceding fiscal year, and shall transfer those moneys to the general fund of the county.
