(a) Religious entities. A religious corporation, association, educational institution, or society is permitted to give preference in employment to individuals of a particular religion to perform work connected with the carrying on by that corporation, association, educational institution, or society of its activities. A religious entity may require that all applicants and employees conform to the religious tenets of such organization. However, a religious entity may not discriminate against a qualified individual, who satisfies the permitted religious criteria, on the basis of his or her disability.

(b) Regulation of alcohol and drugs. A covered entity:

(1) May prohibit the illegal use of drugs and the use of alcohol at the workplace by all employees;

(2) May require that employees not be under the influence of alcohol or be engaging in the illegal use of drugs at the workplace;

(3) May require that all employees behave in conformance with the requirements established under the Drug-Free Workplace Act of 1988 (41 U.S.C. 701 et seq.);

(4) May hold an employee who engages in the illegal use of drugs or who is an alcoholic to the same qualification standards for employment or job performance and behavior to which the entity holds its other employees, even if any unsatisfactory performance or behavior is related to the employee's drug use or alcoholism;

(5) May require that its employees employed in an industry subject to such regulations comply with the standards established in the regulations (if any) of the Departments of Defense and Transportation, and of the Nuclear Regulatory Commission, regarding alcohol and the illegal use of drugs; and

(6) May require that employees employed in sensitive positions comply with the regulations (if any) of the Departments of Defense and Transportation and of the Nuclear Regulatory Commission that apply to employment in sensitive positions subject to such regulations.

(c) Drug testing—(1) General policy. For purposes of this part, a test to determine the illegal use of drugs is not considered a medical examination. Thus, the administration of such drug tests by a covered entity to its job applicants or employees is not a violation of § 1630.13 of this part. However, this part does not encourage, prohibit, or authorize a covered entity to conduct drug tests of job applicants or employees to determine the illegal use of drugs or to make employment decisions based on such test results.

(2) Transportation employees. This part does not encourage, prohibit, or authorize the otherwise lawful exercise by entities subject to the jurisdiction of the Department of Transportation of authority to:

(i) Test employees of entities in, and applicants for, positions involving safety sensitive duties for the illegal use of drugs or for on-duty impairment by alcohol; and

(ii) Remove from safety-sensitive positions persons who test positive for illegal use of drugs or on-duty impairment by alcohol pursuant to paragraph (c)(2)(i) of this section.

(3) Confidentiality. Any information regarding the medical condition or history of any employee or applicant obtained from a test to determine the illegal use of drugs, except information regarding the illegal use of drugs, is subject to the requirements of § 1630.14(b) (2) and (3) of this part.

(d) Regulation of smoking. A covered entity may prohibit or impose restrictions on smoking in places of employment. Such restrictions do not violate any provision of this part.

(e) Infectious and communicable diseases; food handling jobs—(1) In general. Under title I of the ADA, section 103(d)(1), the Secretary of Health and Human Services is to prepare a list, to be updated annually, of infectious and communicable diseases which are transmitted through the handling of food. (Copies may be obtained from Center for Infectious Diseases, Centers for Disease Control, 1600 Clifton Road, NE., Mailstop C09, Atlanta, GA 30333.) If an individual with a disability is disabled by one of the infectious or communicable diseases included on this list, and if the risk of transmitting the disease associated with the handling of food cannot be eliminated by reasonable accommodation, a covered entity may refuse to assign or continue to assign such individual to a job involving food handling. However, if the individual with a disability is a current employee, the employer must consider whether he or she can be accommodated by reassignment to a vacant position not involving food handling.

(2) Effect on State or other laws. This part does not preempt, modify, or amend any State, county, or local law, ordinance or regulation applicable to food handling which:

(i) Is in accordance with the list, referred to in paragraph (e)(1) of this section, of infectious or communicable diseases and the modes of transmissibility published by the Secretary of Health and Human Services; and

(ii) Is designed to protect the public health from individuals who pose a significant risk to the health or safety of others, where that risk cannot be eliminated by reasonable accommodation.

(f) Health insurance, life insurance, and other benefit plans—(1) An insurer, hospital, or medical service company, health maintenance organization, or any agent or entity that administers benefit plans, or similar organizations may underwrite risks, classify risks, or administer such risks that are based on or not inconsistent with State law.

(2) A covered entity may establish, sponsor, observe or administer the terms of a bona fide benefit plan that are based on underwriting risks, classifying risks, or administering such risks that are based on or not inconsistent with State law.

(3) A covered entity may establish, sponsor, observe, or administer the terms of a bona fide benefit plan that is not subject to State laws that regulate insurance.

(4) The activities described in paragraphs (f) (1), (2), and (3) of this section are permitted unless these activities are being used as a subterfuge to evade the purposes of this part.
