(a) A physician, in good faith and in the course of the physician's professional practice only, may prescribe, administer and dispense controlled substances, or may cause the same to be administered by a physician assistant, nurse or intern under the physician's direction and supervision, for demonstrable physical or mental disorders but not for drug dependence except in accordance with state and federal laws and regulations adopted thereunder. Notwithstanding the provisions of this subsection the Department of Consumer Protection may approve protocols allowing the dispensing of take-home doses of methadone, by a registered nurse or licensed practical nurse, to outpatients in duly licensed substance abuse treatment facilities. Such dispensing shall be done pursuant to the order of a licensed prescribing practitioner and using computerized dispensing equipment into which bulk supplies of methadone are dispensed by a pharmacist. The quantity of methadone dispensed by such nurse shall not exceed at any one time that amount allowed under federal or state statutes or regulations governing the treatment of drug dependent patients. The Department of Consumer Protection shall conduct inspections of such treatment facilities to ensure that the computerized dispensing equipment and related dispensing procedures documented in the approved protocols are adhered to. see full law

(2) An advanced practice registered nurse having been issued a license pursuant to section 20-94a shall, for the first three years after having been issued such license, collaborate with a physician licensed to practice medicine in this state. In all settings, such advanced practice registered nurse may, in collaboration with a physician licensed to practice medicine in this state, prescribe, dispense and administer medical therapeutics and corrective measures and may request, sign for, receive and dispense drugs in the form of professional samples in accordance with sections 20-14c to 20-14e, inclusive, except such advanced practice registered nurse licensed pursuant to section 20-94a and maintaining current certification from the American Association of Nurse Anesthetists who is prescribing and administrating medical therapeutics during surgery may only do so if the physician who is medically directing the prescriptive activity is physically present in the institution, clinic or other setting where the surgery is being performed. For purposes of this subdivision, “collaboration” means a mutually agreed upon relationship between such advanced practice registered nurse and a physician who is educated, trained or has relevant experience that is related to the work of such advanced practice registered nurse. The collaboration shall address a reasonable and appropriate level of consultation and referral, coverage for the patient in the absence of such advanced practice registered nurse, a method to review patient outcomes and a method of disclosure of the relationship to the patient. Relative to the exercise of prescriptive authority, the collaboration between such advanced practice registered nurse and a physician shall be in writing and shall address the level of schedule II and III controlled substances that such advanced practice registered nurse may prescribe and provide a method to review patient outcomes, including, but not limited to, the review of medical therapeutics, corrective measures, laboratory tests and other diagnostic procedures that such advanced practice registered nurse may prescribe, dispense and administer. see full law
