Yes, methadone and methadose show up as positive for heroin. That’s why most drug labs will retest such a sample using radio-immuno-assay (RIA) or gas chromatography – mass spectrometry (GC/MS), or both, to get a definitive result.

No methadone does not appear as an opiate on a 5 panel drugs screen or any other drug screen. Drugs on a 5 panel screen include Amphetamines (including Methamphetamine, “Crystal Meth”), Cannabinoids (THC, Marijuana), Cocaine, Opiates (Codeine, Morphine, Heroin, Oxycodone, Vicodin, etc.), & Phencyclidine (PCP).
Methadone does not cross react with the standard opiate drug screen. It must be specifically screened for.Most “drug tests” are really “drug screens”. That is, they only show that there is a probability that a substance similar to a particular drug is present in a sample. However, even though methadone and heroin are both “opioids” and have similar effects, their chemical structures are very different. For this reason, methadone does not react with the drug screens used to look for heroin. Therefore treatment programs use separate screens for methadone and heroin-type opioids (such as morphine and codeine).Opium is a black, gooey extract of the opium poppy (papaver somniferum). The main active ingredients in opium are the drugs morphine and codeine. These and other drugs found in or manufactured from opium are called “opiates”. Heroin is made from morphine so it is also an opiate.
There are also drugs with effects like those of morphine but which are manufactured entirely in a laboratory. Methadone is an example of such a man-made drug. The term “opioid” is used to describe all these synthetic drugs as well as the ‘natural’ opiates. In other words, morphine, codeine, heroin, and methadone are all “opioids”, but only morphine, codeine, and heroin are “opiates.”
