(a) LEAD programs funded pursuant to this chapter shall consist of a strategy of effective intervention for eligible participants consistent with the following gateways to services:

1. (1) Prebooking referral. As an alternative to arrest, a law enforcement officer may take or refer a person for whom the officer has probable cause for arrest for any of the offenses in subdivision (b) to a case manager to be screened for immediate crisis services and to schedule a complete assessment intake interview. Participation in LEAD shall be voluntary, and the person may decline to participate in the program at any time. Criminal charges based on the conduct for which a person is diverted to LEAD shall not be filed, provided that the person finishes the complete assessment intake interview within a period set by the local jurisdictional partners, but not to exceed 30 days after the referral.

2. (2) Social contact referral. A law enforcement officer may refer an individual to LEAD whom he or she believes is at high risk of arrest in the future for any of the crimes specified in subdivision (b), provided that the individual meets the criteria specified in this paragraph and expresses interest in voluntarily participating in the program. LEAD may accept these referrals if the program has capacity after responding to prebooking diversion referrals described in paragraph (1). All social contact referrals to LEAD shall meet the following criteria:

   1. (A) Verification by law enforcement that the individual has had prior involvement with low-level drug activity or prostitution. Verification shall consist of any of the following:

      1. (i) Criminal history records, including, but not limited to, prior police reports, arrests, jail bookings, criminal charges, or convictions indicating that he or she was engaged in low-level drug or prostitution activity.
      2. (ii) Law enforcement has directly observed the individual’s low-level drug or prostitution activity on prior occasions.
      3. (iii) Law enforcement has a reliable basis of information to believe that the individual is engaged in low-level drug or prostitution activity, including, but not limited to, information provided by another first responder, a professional, or a credible community member.
   2. (B) The individual’s prior involvement with low-level drug or prostitution activity occurred within the LEAD pilot program area.
   3. (C) The individual’s prior involvement with low-level drug or prostitution activity occurred within 24 months of the date of referral.
   4. (D) The individual does not have a pending case in drug court or mental health court.
   5. (E) The individual is not prohibited, by means of an existing no-contact order, temporary restraining order, or antiharassment order, from making contact with a current LEAD participant.

(b) The following offenses are eligible for either prebooking diversion, social contact referral, or both:

1. (1) Possession for sale or transfer of a controlled substance or other prohibited substance where the circumstances indicate that the sale or transfer is intended to provide a subsistence living or to allow the person to obtain or afford drugs for his or her own consumption.
2. (2) Sale or transfer of a controlled substance or other prohibited substance where the circumstances indicate that the sale or transfer is intended to provide a subsistence living or to allow the person to obtain or afford drugs for his or her own consumption.
