ToxTests | EDDP Drug Test Dip Cards

EDDP is the primary metabolite of methadone. Methadone is a synthetic opiate agonist that is often used in detoxification programs as an oral substitute for heroin or other morphine-like drugs to suppress withdrawal symptoms and/or to maintain chronic relapsing heroin addicts.

Measurement of EDDP instead of methadone for compliance can detect those individuals on the compliance program selling their methadone into the illicit drug market and spike their urine with a small quantity of methadone to cover their diversion. Their urine may test positive for methadone but would not test positive for EDDP, since the drug was not ingested and therefore never metabolized.
