'''VM''' ('''Edemo''') is a "V-series" [[nerve agent]] closely related to the better-known [[VX (nerve agent)|VX nerve agent]].<ref name="emergency">{{ cite book | last = Burke | first = R. | title = Counter-Terrorism for Emergency Responders | edition = 2nd | year = 2006 | publisher = CRC Press | isbn = 978-0-8493-9923-7 | page = 94 | doi = 10.1201/9781420009903.fmatt | doi-broken-date = 2024-11-12 | url = https://books.google.com/books?id=ZavD-EaJy74C&pg=PA94 }}</ref>

Like most of the agents in the V-series (with the exception of VX), VM has not been extensively studied outside of [[military science]]. Little is known about this [[chemical compound]] other than its [[chemical formula]].<ref name="emergency"/>

It is commonly theorized that the so-called "second-generation" V series agents came from a [[Cold War]] era [[Russia]]n [[chemical weapons]] development program. They may have been developed sometime between 1950 and 1990. They have similar [[lethal dose]] levels to VX (between 10 and 50&nbsp;mg) and have similar [[VX (nerve agent)#Symptoms of exposure|symptoms]] and [[method of action]] to other nerve agents that act on [[cholinesterase]]. The treatment remains the same, but the window for effectively treating second generation V series [[seizure]]s is shorter. In addition to the standard seizures, some of the second generation V series agents are known to cause [[coma]]s.<ref name="emergency"/>
