Your lack of punctuation made this a pretty hard post to understand but I'll try anyway. You're not a regular user of
cocaine? When was the last time you used cocaine? If you're not a regular user, you're urine will be clean in three or four days, but with chronic use it will stay in your system a lot longer. I had a buddy that went to rehab for cocaine and failed for it after two weeks clean. I'm assuming cocaine is the only
drug you are using so I think you'll be fine if you don't use between now and then. If you do decide to bring in a substitute specimen then you should heat it up to body temperature as some places test for temperature, pH, and creatine. That being said I think you'll be fine with your own urine. Good luck
