How long does it take to get cocaine out of your system to pass a UA?

36-72 hours, so about a week

cocaine stays in your body for about 2-3 days from the day of intake

If used on a single occasion and in a typical dose, the average detection period for cocaine is 2-3 days. Frequent or heavy use may result in longer detection periods.

usually within 48-72 hours, but depends on your metabolism...drinking alot of water will help flush it through faster.

Any significant level of cocaine would be undetectable within 3 days.
