Soul drop

Soul drop was a highly addictive drug created by Adam and the Scourge to destroy humanity.

History
After returning as a computer A.I. in the Initiative complex, Adam allied with the Scourge and oversaw the capture and incineration of countless humans, extracting their negative emotions and souls from the remains and transforming them into soul drops, which he planned to sell on the black market and watch as the human race destroyed itself over the drugs.

To power the production of the soul drops, Adam and the Scourge hosted forced demon gladitorial fights in the Initiative's remains, gaining strength from the negative energy. When Buffy Summers was captured and forced to participate, she drained the soul drops and sparked a rebellion amongst the fighters, shutting down the production of them for good.
