Black Nova is an addictive pleasure drug manufactured by the Nabia in which the first hour is black indeed. Many users report severe depression and nearly all who are capable experience the phenomenon of it "coming out both ends." However, once the black period is over, the nova period kicks in as your pleasure centers all-but-explode with wave after wave of pleasure that lasts for a couple of hours. It's typically injected for maximum effect, but it can also be microdosed orally for more recreational users.
