N.J. Stat. § 26:2B-15
Any person who is intoxicated and who voluntarily applies for treatment or is brought to a facility by a police officer or other authorized person in accordance with section 10 of P.L. 1975, c.305 (C.26:2B-16) may be afforded treatment at an intoxication treatment center or other facility. Any person who is a person with an alcohol use disorder and who voluntarily applies for treatment may be afforded treatment at an intoxication center or other facility.
As soon as possible after the admission of any person, the administrator of the facility shall cause such person to be examined by a physician or by a medically competent individual designated by the department and under the supervision of a physician. If, upon examination, a determination is made that the person is intoxicated or is a person with an alcohol use disorder, and adequate and appropriate treatment is available, the person shall be admitted. Admission shall not be denied on the basis that the person is currently receiving medication assisted treatment for a substance use disorder administered by a licensed treatment provider, including but not limited to methadone, buprenorphine, naltrexone, or any other medication approved by the Food and Drug Administration for the treatment of a substance use disorder. If any person is not admitted for the reason that adequate and appropriate treatment is not available at the facility, the administrator of the facility, acting whenever possible with the assistance of the director, shall refer the person to a facility at which adequate and appropriate treatment is available. In the event that a person is not admitted to a facility, and has no funds, the administrator shall arrange for the person to be assisted to the person's residence, or, if the person has no residence, to a place where shelter will be provided.
Any person admitted to a facility may receive treatment at the facility for as long as the person wishes to remain at the facility or until the administrator determines that treatment will no longer benefit the person; provided, however, that any person who at the time of admission is intoxicated and is incapacitated, shall remain at the facility until the person is no longer incapacitated, but in no event shall the person be required to remain for a period greater than 48 hours.
When a person is admitted to a facility, the facility shall provide notice of admission to the person's spouse, parent, legal guardian, designated next of kin, or other designated emergency contact, as soon thereafter as possible, provided that:
The manner in which any person is transported from one facility to another, or from a facility to the person's residence, and the financing thereof, shall be determined by the director in accordance with rules and regulations promulgated by the department.
When a patient is discharged or otherwise released from treatment at a facility, the patient shall be encouraged to consent to appropriate outpatient or residential aftercare treatment.
When a patient voluntarily withdraws, or is involuntarily evicted from a transitional sober living home, halfway house, or other residential aftercare facility, the facility shall provide notice of the patient's release from care to the patient's spouse, parent, legal guardian, designated next of kin, or other designated emergency contact, provided that:
