This is a basic report that refutes what a lot of people are telling me but confirms what a lot of pot smokers tell me. 11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid or 9-carboxy-THC is a metabolite of delta-9-THC. This metabolite is what urine tests look for because it is produced by delta-9-THC. What this document says is "80%-90% of the total dose of delta-9-THC is excreted within 5 days--approximately 20% in urine and 65% in feces." FreeVibe's site and many other sources maintain that it remains in the body for more than 2 weeks and up to 60 days.
