Idaho Drug Testing Laws for Employers

What You Are Buying

Idaho Code Title 72, chapter 17 is opt-in, and its purpose clause states the deal directly: the act establishes voluntary guidelines that, when complied with, will find an employee who tests positive at fault and will constitute misconduct under the employment security law, resulting in denial of unemployment benefits.

Testing is lawful either way. Section 72-1702(1) makes private-employer testing lawful as a condition of hiring or continued employment provided the requirements and procedures comply with the Americans with Disabilities Act, subsection (3) confirms the act does not change at-will status, and 72-1710(1) provides that no cause of action arises from the absence of a program.

Compliance buys four things: the unemployment misconduct finding, the liability limitations in 72-1710, the false-result protections and rebuttable presumption in 72-1711, and eligibility for a premium reduction.

The Premium Reduction Has No Number

This deserves stating plainly, because it is the detail most summaries blur. Idaho Code 72-1716(1) provides that for each workers' compensation policy issued or renewed on or after July 1, 1999, a reduction in premium may be granted if the insurer determines the insured has established and maintains a complying program.

There is no statutory percentage. There is no certifying state agency. And the words are permissive on both sides — "may be granted," "if the insurer determines." This is not the Florida or Georgia arrangement where a number is fixed in statute and the insurer must honor it.

So if a vendor or broker has quoted you an Idaho percentage, confirm it against the carrier's filed rating plan rather than against the code, because we found no percentage in the code. Subsection (2) separately provides that the state or a political subdivision testing all employees and applicants for whom testing is not constitutionally prohibited shall qualify for and may be granted the reduction.

The Most Permissive Random Rules on This Site

Random is listed among the test types a policy may use, and that is nearly all the chapter says about it. There is no selection-rate cap, no requirement that the pool be limited to safety-sensitive positions, no rule about whether supervisors must be included or excluded, and no definition of random or requirement of a scientifically valid selection method.

Contrast that with Iowa, which dictates the selection tool and who may operate it, or Montana, which requires supervisors in the pool and a rate fixed in advance. Idaho leaves all of it to you.

The real constraints are modest: the policy has to list random among the test types; the collection and confirmation requirements of 72-1704 still apply; employee testing time is compensable work time with the employer bearing the cost; and testing must comply with the ADA.

Policy and Procedure

• The policy must state that violating it may result in termination due to misconduct — the sentence that unlocks the unemployment benefit.
• List the test types used, from a menu including baseline, pre-employment, post-accident, random, return to duty, follow-up and reasonable suspicion.
• Drug confirmation on the same sample by a laboratory using a chromatographic technique such as GC-MS or another comparably reliable method. Notably, the chapter does not require a SAMHSA-certified laboratory.
• Alcohol confirmation: a positive initial saliva screen requires a confirmatory test using a different methodology of higher reliability; a positive breath result requires a confirmatory breath test conducted no earlier than 15 minutes after the initial test, or another more reliable confirmatory test.
• Collection standards: reasonable and sanitary conditions, trained collectors, privacy, sample labeling, chain of custody and scientifically accepted analytical methods.
• Written notice of a positive identifying the substance, plus an opportunity to discuss and explain it with a medical review officer or other qualified person.

One provision worth knowing if you are unionized: a policy negotiated with a collective bargaining representative, or consistent with the collective bargaining agreement, earns the full benefits of the chapter even if it does not match every statutory provision. That is an unusually accommodating rule.

No Cannabis Law to Work Around

Idaho has neither an adult-use nor a medical cannabis program. Marijuana and tetrahydrocannabinols remain Schedule I under Idaho Code 37-2705(d), with narrow carve-outs for the permitted THC content in industrial hemp, for nabiximols in an FDA-approved drug product, and for dronabinol in specified FDA-approved formulations.

No medical cannabis registry, patient certification scheme or employment nondiscrimination provision for cannabis users was located. So a national panel that screens for THC needs no Idaho modification, and none of the marijuana-specific limits now constraining programs in neighboring states applies here.

Two prescription-related protections still do. Section 72-1706(1) gives the employee or applicant an opportunity to explain a positive to a medical review officer or other qualified person, which is where a lawful prescription is raised. And the ADA compliance condition in 72-1702(1) is the operative constraint on acting against someone taking lawfully prescribed medication.

Workers' Compensation

Idaho Code 72-208(2) denies income benefits where intoxication is a reasonable and substantial cause of an injury — except where the employer furnished the intoxicants, or permitted the employee to remain at work knowing of the intoxication. That second exception is the same supervisor trap New Hampshire has: tolerating a suspected impaired worker costs you the defense.

Where This Lands

Idaho's employment base runs through agriculture and food processing, semiconductor and electronics manufacturing, healthcare, construction, trucking and logistics, wood and paper products, and mining. For employers with meaningful turnover in hourly roles, the unemployment misconduct finding is usually the part of this chapter worth the paperwork — more reliably than a premium reduction the statute never quantifies.
