how long does cocain stay surrounded by the body system?
Cocaine has a half-life of one hour. It is metabolized to benzoylecgonine and ecgonine methyl ester, which are both excreted contained by the urine. In the presence of alcohol, a further active metabolite, cocaethylene is formed.
Because it is water-soluble, cocaine will one and only remain in traceable amounts for around 1-3 days.unlike other recreational drugs (i.e. marijuana) that are lipid-soluble and remain in the body for longer period of time.
With normal functioning kidneys 24-48 hours.
Cocaine can remain present contained by a person's body as detected by a urine test for over a week after injesting the drug.
Also, traces of cocaine can be found contained by the hair and stay within it until either that coat grows out or is removed (cut, plucked, etc.)
3 days in urine 4yrs curls

Research speak that 24-72 hours
