Cocaine's half-life: Is relatively short (0.5-1.0 hrs) so it's gone from your system w/i a day; its primary metabolite benzoylecgonine, however, has a longer half-life (5-8 hours) & can generally be detected for 24-80 hours after Cocaine use or exposure. Tests screen for both Cocaine & its metabolite.
