Will crack show up in urine after 3 days?
yes it usually stays in your system for 7-10 days
Answer Cocaine will show in a urine test for a minimum of 3-5 days, depending on how heavy and how often you used. The metabolite benzoylecgonine will show for considerably longer. So even if you did pass a urine test for cocaine, you could still get caught out with the metabolite (benzoylecgonine).
