Cocaine Clearance Time in Long Term Users
Q: I am 32, 5’4 about 180 lbs. I was a “few times of week” user of cocaine. I would smoke it, mixed with tobacco. Last time I used was 10 days ago. I have to take a urine test. I have been drinking water and cranberry juice. How likely is it that I will pass this urine test tomorrow?
After a one time session of the drug, cocaine and its metabolite usually take 4 to 5 days to get eliminated from the body.
However, since, you have been a chronic user of the drug, nothing can be said for sure.
With repeated doses of cocaine, the elimination time gets doubled. This happens with each dose. So, after the second dose taken, the elimination time is a week, after the third dose it is two weeks and so on.
Why Does This Happen?
In chronic (long term) users, the drug gets deposited in different organs of the body, like the liver etc. The drug has a tendency to get deposited or dissolved in fatty tissue present in the liver, subcutaneous fat and elsewhere. This deposited drug is difficult to eliminate.
Usually, a drug free time period of 45 days is required to assure that the drug would not show up in the urine test of chronic user.

Blood tests are even more accurate. Hair tests are sometimes done which show every drug ever taken when that hair was growing.
