(a) The head of each agency, department, commission, bureau, board, college, university, institution, or authority shall ensure an analysis is completed on all jobs in his or her organization to determine those positions whose duties and responsibilities warrant conducting an established test for illegal drugs in accordance with the provisions of this Code section. The analysis must be completed by July 1, 1995. All jobs established after this date must undergo a similar analysis no later than six weeks after establishment. An applicant for a designated position shall undergo a drug test consistent with these provisions. Organizations with positions covered under the classified service of the state merit system shall consult with the commissioner of personnel administration before making final determinations and shall provide the commissioner with a list of designated positions and accompanying documentation and analysis.

(b) An applicant for state employment who is offered employment in a position designated by the head of the agency, department, commission, bureau, board, college, university, institution, or authority as requiring a drug test shall, prior to commencing employment or within ten days after commencing employment, submit to an established test for illegal drugs. All costs of such testing shall be paid from public funds by the employing agency or unit of state government. Any such test which indicates the presence of illegal drugs shall be followed by a confirmatory test using gas chromatography/mass spectrometry analysis. If the results of the confirmatory test indicate the presence of illegal drugs, such results shall be reviewed and interpreted by a medical review officer to determine if there is an alternative medical explanation. If the applicant provides appropriate documentation and the medical review officer determines that it was a legitimate usage of the substance, the result shall be reported as negative. Any applicant who fails to provide an alternative medical explanation shall be reported by the medical review officer as having a positive test result. Any applicant offered employment who refuses to submit to an established test for illegal drugs or whose test results are positive shall be disqualified from employment by the state. Such disqualification shall not be removed for a period of two years from the date that such test was administered or offered, whichever is later. The State Personnel Board shall develop rules for the administration of the test and any verification procedures for positions covered under the state merit system. Other covered units of state government shall also develop rules governing these procedures. The results of such tests shall remain confidential and shall not be a public record unless necessary for the administration of these provisions or otherwise mandated by other state or federal law.
