The city shall require an employee to submit to a controlled substances test when the city has reasonable suspicion to believe that the employee has violated the prohibitions of this title concerning controlled substances. The city’s determination that reasonable suspicion exists must be based on specific, contemporaneous, articulable observations concerning the appearance, behavior, speech or body odors of the employee. The observations may include indications of the chronic and withdrawal effects of controlled substances. (Ord. 12-001 § 3, 2013)
