A drug that makes it possible to work even harder would only ever be popular in one place: the Action Center, where people have been known to have their need for sleep surgically removed. Technically, Dilligenz is illegal, but since a cabal of its users informally seized power in the Action Centre, that’s more or less a moot point.
The real problem with Dilligenz is that it’s made from the brains of other human beings. The process is as painless as anything involving a syringe can be, but tends to leave the ‘donor’ rather docile. As bad a crime against humanity that is, Dilligenz II is worse: a stronger version of the drug, it tends to leave its ‘donors’ in persistent vegetative states. Which is why none of them are volunteers.
Actually, all of the above is a story put about for political reasons connected to maneuverings inside the Action Centre. In truth, Dilligenz is manufactured from a plant extract, and what limited effects it has are placebos.
