How long does cannabis stay in the blood stream if taking 4 to 1 ratio, 3mil,3 x's/day?

If you are taking THC and getting a "high" effect from it 3x’s a day, then I would imagine about 4-6 weeks with exercise, good water intake, and good diet. If you are on the heavier side, have a fatty diet, or do not exercise then it can take longer. This is for a hypothetical urine test. It will leave your blood stream much sooner than this.
