... Anyone?
Uppers including cocaine and amphetamines (speed, meth, adderall, etc.) will increase focus and mental stamina. A player using them will feel sharper, more alert, and more energized, and can play with a high degree of focus for much longer before fading, especially if they can sneak off for repeated doses.
Of course, they may impair judgment, decision-making, and logical/analytical abilities enough to hurt your game as well, but they are an unfair advantage on the execution side of the game.
