(1) Urinalysis is the most common and practical procedure to test for tetrahydrocannabinol metabolites in the human system. THC metabolites will be present in urine for up to one month after last use in regular users. The only way to correlate impairment with drug concentration is to determine parent -THC - drug levels. This requires analysis of either blood or saliva - still being researched. (2) Urine drug screens for THC metabolites are conducted by immunoassay and cost approximately $15 to $17. Positive urine samples are often then confirmed using gas chromatography/mass spectrometry with the average cost being $55. Blood testing for parent THC levels using GC/MC costs an average of $55.
