The primary method for urinalysis detection is enzyme immunoassay or radioimmunoassay. This method is inexpensive, quick, and accurate. This is also useful for confirmation of abstinence. Blood samples may be used to measure quantitative levels of cannabinoids. Saliva testing is a newer technology for detection. The presence of delta-9-THC in oral fluid is a better indication of recent use than the presence of 11-nor-delta-9-THC-9-COOH detected in urine. Hair analysis is not a sensitive enough tool to detect cannabinoids.
