Cocaine is detected in blood for a relatively short period of time 12-48 hours.

There should not be a problem with a blood test 8 days after use.

i read that it could stay in your blood for months, is this true and if i can pass an over the counter urine test does that mean that all trase's of cocaine is out of my system?

You can read all kinds of information on the web including a site from the Flat Earth Society.

The answer I gave you was from a reputable medical journal. I will be happy to give you the reference if you desire.

no need for that, thank you very much.
Expert:  Family Physician replied 5 years ago.
The reports of extended detection apply to hair testing (90+ days), urine testing (particuarly in individuals who are heavy daily users). The blood tests have shorter detection periods.
