When the parole authority concludes that there are reasonable grounds for believing that a person on parole is addicted or habituated to, or is in imminent danger of addiction or habituation to, controlled substances or alcohol, it may, in accordance with procedures used to revoke parole, issue an order to detain or place the person in a substance abuse treatment control unit for a period not to exceed 90 days. The order shall be a sufficient warrant for any peace officer or employee of the Department of Corrections to return the person to physical custody. Detention pursuant to the order shall not be deemed a suspension, cancellation, or revocation of parole until the parole authority so orders pursuant to Section 3060 of the Penal Code. A parolee taken into physical custody pursuant to Section 3060 of the Penal Code may be detained in a substance abuse treatment control unit established pursuant to this article.
No person on parole shall be placed in a substance abuse treatment control unit against his or her will.
