Cocaethylene, Urine, Qualitative Screen

What Is Cocaethylene

Cocaethylene is a compound that the body produces when cocaine and alcohol are consumed at the same time. It is not present in either substance alone, so its detection is considered a marker of combined use. It is chemically related to cocaine and can be detected in urine after such combined exposure.

How the Test Works

A urine sample is collected and analyzed with a screening method designed to detect the presence of cocaethylene. Screening tests give a preliminary result, and a positive screen may be followed by a more specific confirmatory method to verify the finding. The test is qualitative, meaning it reports whether cocaethylene is detected rather than an exact amount.

What a Positive Result Means

A positive result suggests that cocaine and alcohol were used together within the detection window of the test. Because results can be affected by factors such as how recently substances were used and how the sample was handled, positive screens are typically confirmed with a second, more definitive method before being acted upon.

What a Negative Result Means

A negative result means cocaethylene was not detected in the sample at the test's level of detection. This generally indicates no recent combined alcohol and cocaine use, but it does not rule out use that occurred outside the detection window or use of one substance without the other.
