We as humans have nerve receptors on some areas of our brain called the cannaboid receptors which are found in the area that affects pleasure, memory,thoughts,concentration, sensory,time perception, co ordination and movement.  A week after smoking cannabis only 60-70% of the THC has left the body because it is stored in the body fat. It takes about 4-6 weeks before THC is undetectable in the blood. On the other hand, the psychoactive effects are gone after a couple of hours.
 Cannabis has effects both on the body (physiological) and the mind (psychoactive). The physiological effects may include increased heart rate, reddening of the eyes, dryness in the mouth, reduced pressure in the eyeball (intraocular pressure) and muscle relaxation.
