Can my employer drug test me in Texas?

Federal & State Law Editorial TeamLast reviewed: 2026-05-18

1. Federal Framework

Drug-Free Workplace Act of 1988 applies to federal contractors over $100,000. DOT regulations (49 C.F.R. Part 40) cover CDL drivers, pilots, pipeline workers. Otherwise no federal restriction on private employer testing.

2. State Drug-Testing Statute

Texas has no general statute regulating private-employer drug testing. Tex. Lab. Code § 411.091 establishes the voluntary Texas Workers' Compensation Drug-Free Workplace program: employers with 15+ employees may adopt a written policy, post notice, conduct testing, and provide EAP referrals. Compliance qualifies for premium credits and creates a rebuttable presumption that a workplace injury was caused by intoxication, denying WC benefits per Tex. Lab. Code § 406.032.

3. Test Categories

Pre-employment, random, reasonable suspicion, post-accident, return-to-duty, and follow-up testing all permitted. No statutory restrictions on frequency or selection methodology for private employers outside the voluntary program.

4. Required Procedures

Outside § 411.091's voluntary program, no statutory procedures apply. Best practice (and § 411.091 requires): written policy, 60-day advance notice before implementation, SAMHSA-certified lab, MRO review, GC/MS confirmation.

5. Marijuana Considerations

Texas has no recreational marijuana law. The Compassionate Use Program (Tex. Health & Safety Code Ch. 487) permits low-THC cannabis for qualifying patients but provides NO employment protections. Employers may discipline employees for any marijuana use, on or off duty.

6. Safety-Sensitive Carve-Outs

DOT-covered transportation workers, pipeline operators (49 C.F.R. Part 199), and oil/gas industry employees under OSHA process-safety regs subject to mandatory federal testing.

7. ADA / Disability

Current illegal drug use not protected. Recovering addicts in treatment protected. Prescription medication use, including for disabilities, may require accommodation analysis under Tex. Lab. Code Ch. 21 and federal ADA.

8. Remedies for Improper Test

Limited. Texas is at-will; no public-policy exception covers drug testing. Possible claims: defamation (if results published), invasion of privacy (rare, narrow), breach of contract if employer violates its own written policy, ADA accommodation claim.
