Hello from JustAnswer. This is Dr. Love.

No, a sexual encounter with someone that uses drugs would not cause you to fail a drug test.

If the test was done today and you already have the results, that would typically be from a screening test, and there is a fair amount of false positives on screening tests, even in people that are not taking any other substances that have been identified to cause false positives. Was the urine specimen sent for a confirmatory test, such as GC/MS?

If the only issue is whether you could have been exposed through sex, then you will definitely not test positive on the confirmatory test, which will show that the screening test was a false positive. The amount of cocaine in semen is like most body fluids, and is measured in ng. This compares to the usual dose of cocaine taken fro recreation that is measured in mg, which is a million times higher than the ng in the semen. Even if there is absorption of this small amount, it will then be so diluted in the recipient that it will not exceed the threshold of detection for a urine drug test.

So, if you are confident that there is no other potential exposure, such as the partner surreptitiously giving you cocaine, then you can be equally confident that the confirmatory test will be negative.

If I can provide any further information, please let me know.

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.
