How long does cocaine stay in your system

A few days it can be detected.

Cocaine is expected to be present in the body for 72 hours since its intake
Cocaine is expected to be detected in your urine for 1-3 days since its intake provided the intake is only once
Habituated use of cocaine results in traces of cocaine being detected in urine for up to 12 weeks.
Cocaine is said to be retained in your hair for a period of 3 months since its intake.
There are also reports available that suggest the presence of cocaine for a time frame of 25 years since its intake.

I've passed within 24 houras but I am thin and I burn the candle at both ends so to speak...3-6 days is what I say...

Cocaine is metabolised by your liver fairly quickly and turned into a metabolite called benzoylecgonine, you only urinate about 1% of cocaine out. This metabolite is what testers use to detect cocaine use. It can remain in your body for up to 8 days (in heavy users). The hair testing method is able to detect coke alot later. Imagine a small molrcule of cocaine is lodged inside a hair when your using. As long as the hair is still on your body the molecule will be trapped inside it and will be detectable. I suppose if you shaved every single hair off your entire body the testers would have nothing to test!
