Indiana drug testing law is located in the Indiana Code in the sections below. Administrative rules are not covered here.

Sec. 22-9-5-4.

As used in this chapter, "covered entity" means an employer, an employment agency, a labor organization, or a joint labor-management committee.

Sec. 22-9-5-6.

(a) As used in this chapter, "disability" means with respect to an individual:

(1) a physical or mental impairment that substantially limits at least one (1) of the major life activities of the individual;

(2) a record of an impairment described in subdivision (1); or

(3) being regarded as having an impairment described in subdivision (1).

(b) As used in this subsection, "illegal use of drugs" means the use of drugs the possession or distribution of which is unlawful under the Controlled Substances Act. The term does not include the use of a drug taken under the supervision of a licensed health care professional or another use authorized by the Controlled Substances Act (21 U.S.C. 812) or other provisions of federal law. For purposes of this chapter, an individual shall not be considered disabled solely because the individual is currently engaging in the illegal use of drugs. However, this subsection does not exclude as an individual with a disability an individual who:

(1) has successfully completed a supervised drug rehabilitation program and is no longer engaging in the illegal use of drugs or has otherwise been rehabilitated successfully and is no longer engaging in the illegal use of drugs;

(2) is participating in a supervised rehabilitation program and is no longer engaging in the illegal use of drugs; or

(3) is erroneously regarded as engaging in the illegal use of drugs but is not engaging in the illegal use of drugs.

It is not a violation of this chapter for a person or other entity covered by this chapter to adopt or administer reasonable policies or procedures, including but not limited to drug testing, designed to ensure that an individual described in subdivision (1) or (2) is no longer engaging in the illegal use of drugs. Nothing in this section shall be construed to encourage, prohibit, restrict, or authorize testing for the illegal use of drugs.

(c) Notwithstanding subsection (b), an individual shall not be denied health services or services provided in connection with drug rehabilitation on the basis of the current illegal use of drugs if the individual is otherwise entitled to those services.

(d) For purposes of this chapter, an individual shall not be considered disabled solely on the basis of the following:

(1) Homosexuality.

(2) Bisexuality.

(3) Transvestism, transsexualism, pedophilia, exhibitionism, voyeurism, gender identity disorders not resulting from physical impairments, or other sexual behavior disorders.

(4) Compulsive gambling, kleptomania, or pyromania.

(5) Psychoactive substance use disorders resulting from current illegal use of drugs (as defined in section 14 of this chapter).

Sec. 22-9-5-24.

(a) A covered entity may do the following:

(1) Prohibit the illegal use of drugs and the use of alcohol at the workplace by all employees.

(2) Require that employees shall not be under the influence of alcohol or be engaging in the illegal use of drugs at the workplace.

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

(4) 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 that the entity holds other employees, even if the unsatisfactory job performance or behavior is related to the drug use or alcoholism of the employee.

(5) With respect to federal regulations regarding alcohol and the illegal use of drugs, require that:

(A) employees comply with the standards established in the regulations of the United States Department of Defense if the employees of the covered entity are employed in an industry subject to those regulations, including complying with regulations, if any, that apply to employment in sensitive positions in the industry, in the case of employees of the covered entity who are employed in those positions (as defined in the regulations of the United States Department of Defense);

(B) employees comply with the standards established in the regulations of the United States Nuclear Regulatory Commission if the employees of the covered entity are employed in an industry subject to those regulations, including complying with regulations, if any, that apply to employment in sensitive positions in the industry, in the case of employees of the covered entity who are employed in those positions (as defined in the regulations of the United States Nuclear Regulatory Commission); and

(C) employees comply with the standards established in the regulations of the United States Department of Transportation if the employees of the covered entity are employed in a transportation industry subject to those regulations, including complying with regulations, if any, that apply to employment in sensitive positions in the industry, in the case of employees of the covered entity who are employed in those positions (as defined in the regulations of the United States Department of Transportation).

(b) For purposes of this chapter, a test to determine the illegal use of drugs shall not be considered a medical examination.

(c) Nothing in this chapter shall be construed to encourage, prohibit, or authorize the conducting of drug testing for the illegal use of drugs by job applicants or employees or making employment decisions based on the test results.

(d) Nothing in this chapter shall be construed to encourage, prohibit, restrict, or authorize the otherwise lawful exercise by entities subject to the jurisdiction of the United States Department of Transportation of authority to:

(1) test employees in, and applicants for, positions involving safety sensitive duties for the illegal use of drugs and for on duty impairment by alcohol; and

(2) remove those persons who test positive for illegal use of drugs and on duty impairment by alcohol under subdivision (1) from safety sensitive duties in implementing subsection (c).

Sec. 22-9-5-25.
