Just want to echo someone else's sub-thread:
Adderall is not at all similar to Huxley's description of Soma. Soma was about feeling good and not having to think of the evil things that make the BNW society possible, not efficiency.

It turns out to refer to a drug in fiction which is named after the Vedic ritual drink.
Original Vedic "soma" is indeed more like a drink of inspiration and ecstasy, with myths similar to the norse "Mead of poetry".
"somasya tA mada indraS cakAra" - "In the exhilaration of soma, Indra has done these great deeds" - is a rig-vedic refrain.
