Focus

Originally developed as a cure for Attention deficit disorder, Focus is an artificial neural attention enhancer which was popular on Earth in the mid 21st century as a student study aid and recreational drug.

It was sold illicitly in complicated packages or 'designs' which required immense concentration to open, thereby necessitating the use of the drug in the first place.

Benefits

Apart from the original intended curative effect, it is difficult to justify the overall benefits of any drug which turns its abusers into mindless morons, however, as has been widely claimed, the discovery of Emti technology may not have been made as swiftly as it was if Milus Blondel hadn't been a devotee.

Demise

The invention of Neural Implants lead to an almost instantaneous decline in the use of the drug and the subsequent end to poly-math-music. Thank God for that.
