Urine: Screening immunoassay detects multiple metabolites of THC while the GC/MS specifically identifies and quantitates THCA. Standard lab cut-off level is 50 ng/ml, but it can be varied from 20 to 100 ng/ml, at the employer’s request in non DOT cases. The assay can be falsely positive as metabolites from other drugs can cross-react with the antibodies used in the immunoassays. Therefore ...

Passive inhalation of marijuana smoke does occur and can result in detectable levels of THC and its metabolites in urine. Clinical studies have shown, however, that it is highly unlikely that a non-smoking individual could unknowingly inhale sufficient smoke by passive inhalation to result in a high enough drug concentration in urine for detection at the cutoff levels used in the Federal ...
Cannabis drug testing - Wikipedia
THC is rapidly metabolized and distributed to body tissues, so that none is excreted in urine unchanged. 11-nor-delta-9-THC-9-carboxylic acid, the principle metabolite, becomes detectable in plasma, feces and urine within hours after exposure.4 In chronic users, THC may accumulate in fatty tissue faster than it can be excreted, leading to longer detection times in urine for chronic users than ...

Urine can be tested for the presence of cannabinoids.1,4,9,14 Due to their lipophilic nature and enterohepatic recirculation, THC can be detected in the urine for several days following acute ingestion.17 The use of human urine drug screening test has been brought into serious question by a recent retrospective study of THC toxicosis in dogs.6 One type of qualitative urine drug screening test is a 5 channel urine …

The use of oral fluid testing for THC provides a convenient means of detection of recent cannabis use and might also be used to discriminate between passive and active cannabis use. The present study compared THC levels, in oral fluid and urine, in subjects actively smoking cannabis and subjects exposed to passive smoke. The urine and oral fluid THC levels were also measured in subjects ...
