California AB 2188 requires non-psychoactive cannabis metabolite protections while retaining full employer rights for pre-employment, post-accident, and safety-sensitive testing.

Under Cal. Lab. Code § 1025 et seq., employers in Parkfield may institute comprehensive drug-free workplace programs including:

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

  • Post-Accident Testing: Mandatory screening following workplace injuries or property damage.
  • Random Testing: Unannounced selection for safety-sensitive roles and machinery operators.
  • Workers' Comp Incentives: Verified testing programs provide premium discounts on state workers' compensation insurance policies.

While cannabis statutes continue evolving across the United States (Medical: Legal; Recreational: Legal in California), 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.

  • 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 Parkfield and California.

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