2. Tramadol
Have you ever had a toothache so bad that it made you just want to run out in front of a Mac truck? I have! And lemme tell ya, even though Tramadol, one of the drugs that contain Phencyclidine (PCP) and may cause false positive on a drug test is a narcotic that can supposedly treat moderate to severe pain… It didn’t do anything! You know what else it can supposedly do? If you guessed, “cause a false positive for PCP,” then you guessed correctly! There have actually been studies to confirm that there is a link between this false positive for PCP triggered when taking tramadol. But what? Something tells me you’re about to find out!
