SAMHSA Certified • MRO Verified

Accredited Drug Testing provides employer and individual screening in Comfort, TX adhering strictly to Tex. Lab. Code § 411.091, federal DOT 49 CFR Part 40 guidelines, and certified SAMHSA laboratory chain-of-custody standards.

Statutory Citation
Tex. Lab. Code § 411.091
Medical Marijuana

Texas Labor Code § 411.091 mandates written policy distribution for employer drug testing programs while supporting broad pre-employment and random testing rights.

Under Tex. Lab. Code § 411.091, employers in Comfort may institute comprehensive drug-free workplace programs including:

  • Pre-Employment Screening: Conditional job offer testing for all applicants.
  • Reasonable Suspicion Testing: Objective, documented behavioral signs of impairment.
  • Post-Accident Testing: Mandatory screening following workplace injuries or property damage.
  • Random Testing: Unannounced selection for safety-sensitive roles and machinery operators.

While cannabis statutes continue evolving across the United States (Medical: Legal (Medical); Recreational: Prohibited in Texas), employers retain the legal prerogative to prohibit substance impairment on job premises, during operational shifts, and while operating company vehicles.

Federal regulations, Department of Transportation (DOT) mandates, and safety-sensitive positions strictly prohibit marijuana use regardless of state cannabis status. ADT provides both standard THC screening and non-THC customized drug panels for private employers wishing to adapt to state-specific hiring preferences.

For commercial drivers, maritime operators, aviation crews, and transit personnel operating in Comfort, all testing follows rigorous Department of Transportation (DOT) standards governed by 49 CFR Part 40:

  • Federal 5-Panel Regulated Urine Screen: Tested for Marijuana, Cocaine, Amphetamines/Methamphetamines, Opioids (Codeine, Morphine, Heroin, Hydrocodone, Hydromorphone, Oxycodone, Oxymorphone), and PCP.
  • SAMHSA Accredited Laboratories: Zero compromise on testing accuracy with gas chromatography/mass spectrometry (GC/MS) confirmation.
  • Medical Review Officer (MRO): Every non-negative specimen is reviewed by a licensed physician MRO before reporting.
  • FMCSA Clearinghouse Reporting: Real-time reporting of verified positive tests and refusals to test into the federal driver clearinghouse database.

Accredited Drug Testing provides legally admissible drug and alcohol screening for county court dockets, child custody hearings, probation requirements, and pretrial diversion programs throughout Comfort and Texas.

All specimens undergo observed or witnessed collection procedures when ordered by the court, accompanied by rigorous Federal Chain of Custody Forms (CCF).
