Marijuana use: persistence and urinary elimination.
Journal of Substance Abuse Treatment
|January 1, 1984
Summary
Chronic marijuana users eliminate THC metabolites slowly. Hospitalized users showed persistent drug levels, impacting treatment and primary care interpretations.
Area of Science:
- Forensic toxicology
- Clinical chemistry
- Pharmacology
Background:
- Marijuana is a widely used illicit substance with gradual elimination from the body.
- Understanding marijuana metabolite persistence is crucial for drug testing and clinical management.
Observation:
- A study monitored ten chronic marijuana users during hospitalization.
- The Syva EMIT Cannabinoid Assay, a urine test for marijuana metabolites, was utilized.
- Two case reports illustrate the monitoring results.
Findings:
- Chronic marijuana users exhibit prolonged excretion of THC metabolites.
- Urinary marijuana metabolite levels can remain detectable for extended periods post-cessation.
- The study provides data on the persistence of cannabinoids in frequent users.
Implications:
- Results inform the interpretation of urine drug test outcomes in chronic users.
- Findings impact the definition of "significant" urinary marijuana levels.
- Clinical implications for addiction treatment programs and primary care settings are discussed.
