I am tested every 2 weeks in order to get my methadone, i have 5 paneldrug test for Methadone
, Benzos, Opiates, COcaine, amphetimines. I have had false positive
for benzos which they thought was just me lying as after all i am only a drug addict(in their opinion anyway).I know people tested negative for Heroin and have used just before going. Ihave Diabetes and have read that can cause false positives along with kidney infections. Anti inflamatorys can cause false positive for marijuana.
