Apparent half-life of excretion of cannabinoids in man

Hum Toxicol. 1983 Oct;2(4):641-4. doi: 10.1177/096032718300200410.


The apparent half-life of excretion of cannabinoids was calculated from their concentration in the urine of 27 psychotic patients. The best estimate was about 4 days but the range was too wide to be of use in predicting time to total clearance from the body of any randomly chosen patient.
