Drug testing and marijuana in Wisconsin.
Wisconsin drug testing and marijuana: illegal (limited cbd), off-duty use protections, and safety-sensitive carve-outs.
What changes in Wisconsin
- Cannabis posture: Illegal (limited CBD). Wisconsin permits limited CBD use; no recreational or broad medical legalization.
"We hire in California, Washington, and Texas — what should our marijuana testing policy look like? Focus on Wisconsin."

- Step 1. Match your Wisconsin drug policy to the current state posture: Illegal (limited CBD).
- Step 2. Carve out safety-sensitive roles explicitly — federal DOT rules override state cannabis protections.
- Step 3. Test based on impairment, not off-duty use, wherever WI protects lawful off-duty conduct.
- Step 4. Retain chain-of-custody records; positive results based on THC alone are increasingly hard to defend without objective impairment evidence.
Applicable Wisconsin statutes and references
- Wis. Stat. §111.335 (conviction-record discrimination)
- Wis. Stat. §973.015
- 15 U.S.C. §1681 et seq. (federal FCRA)
Frequently asked (federal + Wisconsin overlay)
Can employers still drug-test for marijuana?
Yes, in most states. But thirteen states restrict pre-employment testing or protect off-duty use, with safety-sensitive and federal-mandate carve-outs that keep DOT testing unchanged.
What is a non-psychoactive cannabis metabolite?
Carboxy-THC, the metabolite detected by standard urine THC tests, remains in the body for days or weeks after psychoactive THC has cleared. California and Washington treat that positive as no evidence of impairment.
Do off-duty cannabis laws apply to DOT drivers?
No. Every state with an off-duty protection statute carves out DOT 49 CFR Part 40 testing and federally regulated safety-sensitive positions.
What is reasonable-suspicion testing?
Testing based on documented, articulable observations of impairment — appearance, behavior, speech, odor — by a trained supervisor, not on rumor or off-duty conduct.
