No, there's no proof it does, there are certain shampooes and detoxificants that can cause a fake negative in a drugs test, they cost about £100 ($160) for a treatment, but to the best of my knowledge nothing can make a false positive as the drugs tests are based purely on compounds that only certain drugs contain eg THC in marijuana or BZP in ecstacy or LSD

Zanaflex, or better known as Tizanidine, has not been documented to cause false positive in screening tests for drug abuse. Hence if a positive result is registered for the psychoactive drug benzodiazepines, it is likely due to other medications taken by the user that are creating the false positive.
