gchem sets the players speed for the effects for some of the gasses, issue is, the main timer function includes a reset to default gmod speed when you are not affected, in the gchem config (i have a discussion explaining it pinned) is variables for the different speeds, set the default to whatever you want. (i know my method isn't the best way of doing it, but i've had to move on)

If i remove the speed part in the config does it break the mod?
