Drugs of Abuse Testing
Ordering the Right Test at the Right Time,
and What Does it Mean?
Interpretation
September 2009
Now one of the most frequently asked questions in the laboratory is how long can you detect a drug? Well, of course, it varies from drug to drug, but it also varies from sample to sample. Here is an example looking at cocaine and its metabolite. In blood, you can probably only find evidence of cocaine use up to 24 hours, but only through its metabolite benzoylecgonine. If you look in urine, you can find it for up to 3 days.
