SLAM, also known as redline, bounce, or berserker, is a stimulant that eases pain and inhibits the fear response in Humans. It is most commonly administered as a gas, inhaled from small vials of crushed crystals. Now illegal in the United Empire of Earth (UEE), it was initially introduced as a steroid and performance enhancer for athletes. Side effects of prolonged SLAM include involuntary tremors and muscle spasms.
