Drug Testing Laws in Wyoming

Short answer

This is a short page on purpose. We searched Wyoming's labour statutes and did not find a general law telling a private employer how to run a drug test — no written-policy requirement, no laboratory standard, no confirmation rule, no right to your results, no right to explain a positive. If your employer tests you in Wyoming, the terms are largely its own. The one Wyoming provision we did find worth knowing is in the worker's compensation scheme, and its wording is better than most: an injury is excluded only where it was CAUSED BY intoxication or being under the influence — not merely where a test came back positive — and a prescribed drug taken as directed is carved out of the exclusion entirely.

This page describes Wyoming law only. If your role is federally regulated, federal rules apply on top of anything here and generally govern the test itself. This is general information, not legal advice.

Private employers

What we found, and how far that goes: we read the Wyoming Legislature's own compilation of Title 27, the labour and employment title, and the retrievable portion covered general provisions, labour and statistics, and unemployment compensation. Nothing in those chapters governs how a private employer conducts drug or alcohol testing Source 2State legislatureWyoming Statutes Title 27, chapters 1–3 — searched for a general employer drug testing statute — checked 24 Aug 2026. We did not read the rest of the title, other titles, or Wyoming's administrative rules — so this is a statement about our search, not a finding that no such law exists anywhere in Wyoming law Source 2State legislatureWyoming Statutes Title 27, chapters 1–3 — searched for a general employer drug testing statute — checked 24 Aug 2026.

We will say plainly what that means for you in practice. On the evidence we have, an employer in Wyoming is not working within a statutory framework the way one in Alaska, Minnesota, Iowa or Connecticut is. There is no state-law checklist to hold it to, and the protections that employees in those states rely on — written policy, confirmation by a second method, review by a physician, a confidential chance to explain — have no Wyoming equivalent that we located.

So where do the rules come from: from your employer's own policy, from your contract or collective agreement if you have one, from federal law where it applies — and, for a DOT-regulated role, overwhelmingly from the federal rulebook. Read the policy. In a state without a statute, the policy is the rulebook, and it is also the thing an employer can be held to having written.

One thing we are NOT saying: absence of a testing statute is not absence of law. Federal disability law, federal medical privacy rules where they apply, ordinary contract and tort principles, and Wyoming decisions we have not researched all continue to operate. If something has gone wrong with a test in Wyoming, the right conclusion is that this page cannot tell you your position — not that you have none.

Pre-employment testing

What we found: nothing. We located no Wyoming statute restricting pre-employment drug testing, requiring notice to applicants that testing will happen, limiting which substances may be screened for, requiring a confirmation test before an offer is withdrawn, or giving an applicant a right to see the result Source 2State legislatureWyoming Statutes Title 27, chapters 1–3 — searched for a general employer drug testing statute — checked 24 Aug 2026.

Nor did we find the unemployment-benefits mechanism some states use — Wisconsin, for instance, presumes that refusing an employer's pre-employment test is a refusal of suitable work. We read Wyoming's unemployment compensation chapter and found no equivalent Source 2State legislatureWyoming Statutes Title 27, chapters 1–3 — searched for a general employer drug testing statute — checked 24 Aug 2026. That is a genuine difference between the two states, but treat it as read-and-not-found rather than settled.

Practical: if you are asked to test as a condition of a Wyoming job offer, the questions worth asking are the ones the employer's own paperwork should answer. Which substances. Which laboratory. Whether a positive screen is confirmed by a second method before anything is decided. Whether you will be told the result and given a chance to explain a prescription. None of those are guaranteed to you by Wyoming statute as far as we can tell — which makes getting them in writing before you test the whole of your protection.

Random testing

What we found: no Wyoming statute either authorising or limiting random testing by a private employer, and no definition of what makes a selection random Source 2State legislatureWyoming Statutes Title 27, chapters 1–3 — searched for a general employer drug testing statute — checked 24 Aug 2026. There is no safety-sensitive category, because there is no statute in which to define one.

That places Wyoming at one end of a real spread. Alaska permits random testing outright but defines random as a scientifically valid method giving every covered employee an equal chance. Minnesota, Connecticut and Vermont confine it to safety-sensitive roles. Wisconsin makes it MANDATORY for work on public projects. Wyoming, on what we read, says nothing at all — so a selection that keeps landing on the same person has no state-law standard to fail.

Except where federal law reaches you: if you hold a commercial driving licence or work in another DOT-regulated role, random testing is not governed by Wyoming law at all. It is required, and its selection method, rates, panel and consequences are set federally.

Cannabis and employment

The short answer: Wyoming gives employees no cannabis employment protection. Wyoming has not enacted a medical or adult-use cannabis programme, so there is no cannabis statute here to carry an employment clause — nothing like New Jersey's testing restrictions, Nevada's pre-employment rule, New York's off-duty protection or Connecticut's designated-position scheme. And unlike Wisconsin, Wyoming has no off-duty lawful-products protection either, so there is not even a general off-duty conduct provision for the question to be argued under.

A positive marijuana test in Wyoming is therefore governed by the employer's policy, subject to federal disability law where a genuine underlying condition is in play.

One place the distinction does appear: the worker's compensation exclusion discussed below turns on a controlled substance and expressly carves out a prescribed drug taken as directed by an authorized health care provider Source 1State legislatureWyo. Stat. § 27-14-102(a)(xi)(B) — worker's compensation, injury caused by intoxication or controlled substances — checked 24 Aug 2026. Marijuana under a Wyoming prescription is not a thing that exists, so that carve-out does not help with cannabis — but it does mean the exclusion cannot be run against someone taking a lawfully prescribed medication as directed.

On our sourcing: the statement that Wyoming has not legalised cannabis is not drawn from a document we read and recorded, and is flagged for verification with the rest of this page.

How federal rules interact

State law (Wyoming) — the one provision worth knowing: Wyoming's worker's compensation scheme excludes from the definition of 'injury' an injury CAUSED BY the fact that the employee is intoxicated or under the influence of a controlled substance, or both — EXCEPT any prescribed drug taken as directed by an authorized health care provider Source 1State legislatureWyo. Stat. § 27-14-102(a)(xi)(B) — worker's compensation, injury caused by intoxication or controlled substances — checked 24 Aug 2026. The only other item in that same exclusion is a willful intention to injure or kill oneself or another Source 1State legislatureWyo. Stat. § 27-14-102(a)(xi)(B) — worker's compensation, injury caused by intoxication or controlled substances — checked 24 Aug 2026.

Read the wording carefully, because it is more protective than the equivalent in several states. The trigger is CAUSATION, not detection. What is excluded is an injury caused by the employee being intoxicated or under the influence — not an injury that happened to be followed by a positive test. A metabolite in a urine sample days after use is evidence of past use, not of the causal fact the exclusion describes. Whether Wyoming law elsewhere builds a presumption on a positive test, or who carries the burden of proving causation, we did not research and do not assert Source 1State legislatureWyo. Stat. § 27-14-102(a)(xi)(B) — worker's compensation, injury caused by intoxication or controlled substances — checked 24 Aug 2026.

The prescription carve-out is written into the exclusion itself, which matters practically: if you were taking a prescribed medication as directed by an authorized provider, that is not the intoxication the exclusion is about.

To be clear about what it is not: this is a benefits-coverage provision, not a testing law. It gives an employer no authority to test, sets no procedure, requires no confirmation, and grants you no right. It matters after an accident, not before one.

Federal (DOT): in a state with no testing statute, the federal rules are unusually dominant. If your role is DOT-regulated, essentially the whole of the testing regime that applies to you is federal — the panel, the cutoffs, the collection procedure, the medical review officer, the return-to-duty process and the consequences. Nothing in Wyoming law modifies any of it.

Gaps we are naming: the worker's compensation text was read from a commercial reproduction rather than the legislature's own compilation, because the official Title 27 file we retrieved stopped before that chapter Source 1State legislatureWyo. Stat. § 27-14-102(a)(xi)(B) — worker's compensation, injury caused by intoxication or controlled substances — checked 24 Aug 2026 Source 2State legislatureWyoming Statutes Title 27, chapters 1–3 — searched for a general employer drug testing statute — checked 24 Aug 2026. Bills proposing a general drug and alcohol testing act and a state employee testing programme were introduced in Wyoming in 2001; whether anything on either subject was enacted then or since, we did not determine Source 2State legislatureWyoming Statutes Title 27, chapters 1–3 — searched for a general employer drug testing statute — checked 24 Aug 2026. And we searched only Title 27 — occupation-specific and public-employee provisions elsewhere in Wyoming law were not searched at all Source 2State legislatureWyoming Statutes Title 27, chapters 1–3 — searched for a general employer drug testing statute — checked 24 Aug 2026.

Not yet verified for Wyoming

We publish a topic only once it has been checked against Wyoming's own statutes or agency guidance. These are still in research, and their absence above does not mean there is no rule:

  • Medical cannabis
  • Safety-sensitive roles
  • Notice requirements

For these, go to the state's own labour agency rather than a general article.
