Clinical Significance: | Marijuana is a mixture of dried leaves and flowering tops of the plant Cannabis sativa L. The agents that produce the hallucinogenic and other biological effects of marijuana are called cannabinoids. The cannabinoid Δ9-tetrahydrocannabinol (Δ9-THC) is the principal psychoactive ingredient in marijuana and hashish. The compound Δ9-THC is quickly and effectively absorbed by inhalation or from the gastrointestinal tract, and is almost completely metabolized by liver enzymes. Peak plasma levels of Δ9-THC occur within 10 minutes of inhalation and approximately 1 hour after ingestion. Approximately 30% of a dose of THC is excreted as urinary metabolites within 72 hours after exposure. Concentration depends on the total amount of THC absorbed, frequency of abuse, rate of release from fatty tissue, and time of specimen collection with respect to use. In chronic users, THC may accumulate in fatty tissue faster than it can be eliminated. This accumulation leads to longer detection times in urinalysis for chronic users than for occasional users. The Emit® II Plus Cannabinoid Assay detects the major metabolite of Δ9 THC, 11 nor Δ9 THC 9 carboxylic acid, in human urine. It also detects other Δ9 THC metabolites. The cutoff level for distinguishing positive from negative specimens is 50 ng/mL. Passive inhalation of marijuana smoke may produce positive results with low cutoff cannabinoid assays. Urine specimens from nonsmokers can test positive for cannabinoid metabolites, but only after exposure to high concentrations of marijuana smoke in a small, unventilated area. Such extreme exposure conditions clearly are not typical of usual social situations. Positive results for specimens containing other compounds structurally unrelated to cannabinoids have not been observed. While confirmation techniques other than GC/MS may be adequate for some drugs of abuse, GC/MS is generally accepted as a rigorous confirmation technique for all drugs, since it provides the best level of confidence in the result |
