It is not impossible, I made that for drug "Speed", look at these sections GetPlayerVelocity and SetPlayerVelocity . Little help, in function OnPlayerUpdate you check is player on adrenaline, if so, than, getplayervelocity, and setplayervelocity + e.g 0.3, but you need to be careful, and check for max velocity and if it reached limit than dont setplayervelocity + 0.3, because if you run too fast player will die.
