We present this simple multi-drug urine test that detects cocaine, amphetamines, THC, ecstasy (MDMA), morphine, methadone, opiates, phencyclidine, barbiturates, benzodiazepines, and tricyclic antidepressants.
Just leave the detection strips, attached to the test, in the urine sample. If one line appears it is positive, if two lines appear it is negative, and if no lines appears after a while, the test is no valid.
