The prohibitions contained in Section 8.80.040 of this chapter shall be applicable to hospitals, rest and convalescent homes, medical clinics, physical therapy facilities and other places where medical, dental, psychiatric or counseling services are delivered to members of the general public. Operators of facilities treating psychiatric or chemically impaired patients may permit smoking by patients in designated areas provided the medical director of such facility has determined in writing that the practice is beneficial for the recovery or treatment of such patients and that the practice will not interfere with the recovery and treatment of nonsmoking patients, and provided that adequate nonsmoking areas are made available for nonsmoking patients. Neither this section nor Section 8.80.040 of this chapter shall be construed to prevent smoking in locations or otherwise under conditions in which smoking is expressly authorized by or under statutes or administrative regulations applicable to such licensed facilities.
