How dose THC, stay in your blood?

This answer was rated:

how long dose THC, stay in your blood?
This really depends, but if you use marijuana occassionally, it might stay in your system as short as 5 days, but if you use it chronically (daily) then it will stay in your system sometimes up to 30 days.

i have tried an herbal cleanser and used a urine test. The urine test reads boarder line negative. Can i asume that the blood result will be the same.
I can't really tell you for sure one way or the other, but I can tell you that urine cleansers do not work, only time and body metabolism will help to clear your body - but if your urine test is negative, then there is a strong chance a blood test would be negative too, but this depends on the sensitivity of the test they will use if they use blood, many places just use urine.
