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

  • Pre-Employment Screening: Conditional job offer testing for all applicants.

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.

  • 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 San Ygnacio and Texas.

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