Arizona voluntary drug testing law

A written policy is required for workplace testing in Arizona.  Testing or retesting for the presence of drugs or alcohol by an employer shall be carried out within the terms of a written policy that has been distributed to every employee subject to testing or that has been made available to employees in the same manner as the employer informs its employees of other personnel practices, including inclusion in a personnel handbook or manual or posting in a place accessible to employees. The employer shall inform prospective employees that they must undergo drug testing.
