Cocaine will stay and therefore be detected in a person's system for different periods in different organs in the body. In a user's bloodstream cocaine may stay in the user's bloodstream for up to two days. Cocaine may stay in the user's urine for one to three days and may stay in a user's hair for up to three months.

It is interesting to note that while testing for substance abuse most recognized laboratories will not test for the drug, like cocaine, but instead will test for the metabolite of the substance. In the case of cocaine the laboratory will test for 'benzoylecgonine'. This may remain in an addict's bloodstream for up to thirty days.
