If you work or are applying for a job in Arizona and your employer has asked you to take a drug test, you'll want to know your legal rights.

Like many other states, Arizona has laws that allow drug testing in certain situations, as long as the employer follows the procedural rules.

Notice and Procedural Rights for Employees

Have you been illegally asked or required to take a drug test? Even though Arizona law allows employers to drug test, employees and applicants may have legal claims based on how the test was conducted, who was tested, or how the results were used. Here are some examples:
