Methyldihydromorphine (dihydroheterocodeine) is a semi-synthetic opioid originally developed in Germany in 1936, controlled under both domestic law and UN conventions because of its possible potential for abuse. Methyldihydromorphine is related to heterocodeine and is not a synonym for dihydrocodeine. Its structure suggests that it is six to nine times stronger than morphine and 72 times stronger than dihydrocodeine.

So far, little is currently known about this compound. It is a Schedule I controlled substance in the United States with an ACSCN of 9304 and a 2013 annual manufacturing quota of 2 grammes.
