Yes, Atripla can cause a false positive for a high reading of cannibinoids.

Maybe, but even if Atripla showed up on a drug test, as long as there is a valid medical reason to take it (HIV infection), then there should be no problem. This is not a drug used for recreational purposes.

There have been reports of false positives for benzodiazepines and THC for Atripla users in simplistic screening tests, so if you're taking Atripla (or, for that matter, any other prescription medication) you should inform the person who's doing the test about it. This will allow them to do a more precise test that will not give a false positive.

As all drugs, Atripla can produce many side effects. Some side effects it can produce are psychiatric problems, kidney problems, changes in bones density, etc.

It just gave me a false positive for marijuana for a drug screen for a job.
