Practitioner steps for District of Columbia

Step 1. Match your District of Columbia drug policy to the current state posture: Statewide off-duty protection (2023).
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 DC 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.

Frequently asked (federal + District of Columbia 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.
