Arizona Drug Testing Laws for Employers

A Statute That Trades Paperwork for Protection

A.R.S. Title 23, Chapter 2, Article 14 runs from section 23-493 through 23-493.11 and covers policy contents, scheduling, testing procedures, laboratory standards, confidentiality, and the consequences of a positive result.

Compliance is voluntary, and the statute says so outright. But the benefit is not a discount: it is that sections 23-493.06 through 23-493.08 shut down most causes of action against an employer running a conforming program, including claims arising from excluding someone from a safety-sensitive position. For a large Arizona employer, that is worth considerably more than a few percent off a premium.

The Written Policy Is the Gate

Everything else depends on section 23-493.04(A). The policy must be distributed to every employee subject to testing, or made available in the same way you communicate other personnel practices, and it has specific required contents. Prospective employees must be told they will be tested.

An employer that tests without that policy has not broken the law. It has simply forfeited the protections, which is the whole reason to engage with the article in the first place.

Details Worth Knowing

• Random testing is expressly allowed under 23-493.04(C), alongside the job-related purposes in subsection (B), which include investigating possible impairment and investigating workplace accidents.
• Coverage must be uniform. Section 23-493.04(D) requires all compensated employees, including officers, directors and supervisors, to be included on the same basis. A program that exempts management does not conform.
• The employer pays the actual costs of employee testing under 23-493.02(2); applicant testing costs are discretionary.
• Confirmation is required by a different chemical process under 23-493.03(5), and laboratories must be approved or certified by HHS, the College of American Pathologists, or the Arizona Department of Health Services.
• Results are confidential, and samples may not be tested for anything other than unlawful drugs or alcohol, under 23-493.09.
• Union-negotiated and federally mandated policies still receive the article's benefits, under 23-493.10 and 23-493.11.

Marijuana: Medical Cardholders Are Protected

Arizona splits the two categories. A.R.S. 36-2813(B) protects registered medical marijuana cardholders from discrimination based on their status or on a positive test for marijuana components, unless acting otherwise would cost the employer a monetary or licensing benefit under federal law. A.R.S. 36-2814(A)(3) carries a related qualification worth reading alongside it.

Recreational use carries no such protection. The Smart and Safe Arizona Act at A.R.S. 36-2851 preserves employer authority, so Arizona sits well away from states like New Jersey or New York on this question.

What This Means Practically

Arizona rewards an employer that treats the statute as a checklist. If you are testing in Arizona without a conforming written policy, you are carrying all the exposure and none of the protection the state offers for free.

Arizona's large sectors include semiconductor and electronics manufacturing, healthcare, construction, transportation and warehousing, tourism, and aerospace and defense. Several of those involve safety-sensitive roles, which is precisely where the statute's litigation protection is most valuable.
