Technically, that should be MañanacillinTM, which is how it inevitably appears when mentioned in the pages of American Flagg!.
MañanacillinTM is of that class of substances euphemistically referred to as ‘morning after pills’ or abortifacients. Sold in pill form by the Plex, its existence serves primarily to reinforce the general disregard for the consequences of their actions that characterises most of the citizenry of 2030’s Chicago.
Curiously absent from American Flagg! is any religious group decrying MañanacillinTM as the offence against God’s will they would no doubt see it as.
