Legal
Workplace Rights
Zero-Tolerance Protected

Washington RCW 49.44.240 protects job applicants from off-duty cannabis screening restrictions while preserving post-accident, reasonable suspicion, and safety position testing.

Under RCW § 49.44.240, employers in Marcellus 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.
  • 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 Washington), 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 Marcellus, 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 Marcellus and Washington.

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

Fantastic experience from the beginning. Jocelyn was very helpful to me as someone who doesn’t have much experience in needing a test. They were very helpful and walked me through the entire process start to finish. Thank you ADT!

ADT was able to get me the best tests

Dealing with allegation’s of drug use that completely false is stressful, ADT was able to get me the best tests, going back the farthest in the same day with as little hassle as possible, I spoke with 1 person and wasn’t transferred once, and they took my payment, and got me my work order for a clinic as close as possible for the service I needed. 5*
