how long do it take for cocaine to leave your system and to successfully pass a drub test

It depends on how often you use. For first time users, plan on 3-5 days, but don't quote me. I have never used myself, but I have worked with lots of people that have. Take this opportunity to stop and never use again. It ruins lives. I have also heard that cranberry juice helps as well. We all make mistakes. It's time you corrected this one. Just my opinion. Good luck!

how long do it take for cocaine to leave your system and to successfully pass a drub test

I think you mean to ask:

"How long DOES it take for cocaine to leave your system and to successfully pass a DRUG test"

If that is the case, and I am sure it is..... it depends on the test involved, be it blood, urine or follicle.

In the urine and/or blood it takes 2-3 days, approximately, after last usage to be released from your system. However, this is an average and does not take into account high usage and your body's own metabolism. It could take longer if you use regularly and have a low metabolism.

There is a product you can buy to help flush your body out of drugs, alcohol, etc.. I have a friend that did it twice and it worked the second time but not the first time. It is like $80 a box though. I don't know how long that it takes to work but it DOES work. You can buy it at health food stores, etc I believe!
