The answer is body's fat cells. Marijuana has a quantity of vigorous ingredients like THC (tetrahydrocannabinol or delta-9-THC) and CBD, that goes to the bloodstream very rapidly as the marijuana is expended. They then stay in the body for some time after you have smoked or consumed the drug. If marijuana is consumed, rather than smoked, it will take a little longer to be absorbed into the blood – up to an hour and a half. On each time that you smoke or consume marijuana you soak your blood with the active ingredients and the chemicals in your blood are then absorbed by the fat cells. Because of the way it is stowed, THC takes lengthier to fully clear the body than any other common drug. When marijuana is used it is stored in your body fat cells. It is then removed slowly over time through urine and feces.
