For the casual user, marijuana will "show up" for 3 Weeks in a urine test, 6 Weeks in a blood screen and far longer in hair roots tests. For regular users these figures can multiply by a factor of 3 since it takes the body a lot longer to get rid of the substances.

Note of caution: Drinking copious amount of Tee will not speed this process up. Drinking fluids in excess can wash out the minerals in your body and be very harmful to you while not helping you to get rid of the "toxins" you refer to.

Drink, drive and smoke responsively!
