Many factors weigh in detecting the cocaine in urine.

When you screen urine for the cocaine,you are actually measuring benzoylecgonine, which is a metabolite of cocaine.

Generally, the accepted period of time for benzoylecgonine to be detected in urine is three to five days in occasional users of cocaine.

In high dose users above 0.5 gram or more can test positive even after eight days.

In chronic users of extremely high doses of 112 grams in a week, the benzoylecgonine was detected between even 10 to 22 days.
