Hello from JustAnswer. This is Dr. Love.

Cocaine is cleared from the blood stream relatively quickly. The half life of cocaine is about an hour. The physiologic effect for which people take cocaine only occurs during the peaks levels of the drug, so only lasts up to about an hour to an hour and a half. But it really takes 5-6 hours for the blood levels of the cocaine to be negligible.

Since cocaine is cleared from the body quickly, testing will frequently look for a primary metabolite of cocaine, benzoylecgonine. The half life of benzoylecgonine is much longer, about 6 hours, so it also takes much longer for the benzoylecgonine to be cleared from the blood stream, about 30-36 hours.

Is there any further information that would be helpful?

Is there any further medical information that would be helpful?

Thank you to the Physician who answered my question today. The answer was far more informative than what I got from the Physicians I saw in person for my problem.

You have been more help than you know. I seriously don't know what my sisters situation would be today if you had not gone above and beyond just answering my questions.
