In brief: The

The effects of marijuana use usually occur pretty quickly after smoking it and then start to decline after 3 hours of the last use.
Most studies that measure how long thc is detectable in the urine look at occasional use. A positive urine test usually reflects occasional marijuana use within the last 1-3 days. However, with chronic use, some of the thc is stored in fat cells causing a slower release and much longer detection times - up to 5 or 6 weeks.
