ABSTRACT
Goals of Changing Opiate Testing Cutoffs (Tables 34.2 and 34.3) ◾ To substantially reduce the total number of specimens reported as positive for opiates
by laboratories, but veried as negative by the MRO ◾ To shift the emphasis of testing for opiates to the deterrence and detection of heroin use ◾ To reduce unnecessary and excessive costs of retesting without compromising the
original drug deterrent objectives (Figures 34.3 through 34.6)
Urine Drug Tests after Ingesting Food Products Containing Hemp Seeds ◾ Specimens that showed immunoreactivity (not necessarily = or > cutoff) were tested
by gas chromatography/mass spectrometry; some screened positive, most did not. ◾ Gas chromatography/mass spectrometry results were 0 or very close to 0 ng/mL; none
were close to cutoff (50 ng/mL). ◾ Immunoreactivity was likely due to cannabinoids other than delta-9-THC acid; may be
a problem for on-site testing.
