(b) The prosecuting attorney shall review his or her file to determine whether or not paragraphs (1) to (4), inclusive, of subdivision (a) apply to the defendant. If the defendant is found eligible, the prosecuting attorney shall file with the court a declaration in writing or state for the record the grounds upon which the determination is based, and shall make this information available to the defendant and his or her attorney. This procedure is intended to allow the court to set the hearing for pretrial diversion at the arraignment. If the defendant is found ineligible for pretrial diversion, the prosecuting attorney shall file with the court a declaration in writing or state for the record the grounds upon which the determination is based, and shall make this information available to the defendant and his or her attorney. The sole remedy of a defendant who is found ineligible for pretrial diversion is a postconviction appeal.

(c) All referrals for pretrial diversion granted by the court pursuant to this chapter shall be made only to programs that have been certified by the county drug program administrator pursuant to Chapter 1.5 (commencing with Section 1211) of Title 8, or to programs that provide services at no cost to the participant and have been deemed by the court and the county drug program administrator to be credible and effective. The defendant may request to be referred to a program in any county, as long as that program meets the criteria set forth in this subdivision.

(d) Pretrial diversion for an alleged violation of Section 11368 of the Health and Safety Code shall not prohibit any administrative agency from taking disciplinary action against a licensee or from denying a license.This subdivision does not expand or restrict the provisions of Section 1000.4.

(e) Any defendant who is participating in a program authorized in this section may be required to undergo analysis of his or her urine for the purpose of testing for the presence of any drug as part of the program. However, urinalysis results shall not be admissible as a basis for any new criminal prosecution or proceeding.
