Iowa Code § 730.5 governs private sector employee drug testing, requiring written company policy distribution and certified laboratory screening protocols.

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

  • 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.
