can vitamin make a false positive for methadone in urine test ?
my daughters grandmother got a urine test back with a positive for methadone but she doesnt take methadone she does take a bunch of vitamins such as vitamin b12 b6 folic acid superior source vitamin b12,milk thistle, Deva nutrition vegan b12 folic acid
Methadone, only if consumed, would appear in the urine. Please ask her for any previous history of drug addiction, for which she has been prescribed methadone, or any accidental intake of unknown medication.
