Track how many drugs you have consumed within Pardus (a MMORPG set in space) to ensure that you don't become too drugged.
The Drug Clock does not send any data anywhere - it counts when you use drugs (from a blocking building, combat or the nav screen) and displays how long you have until you are "clean" (no longer under the influence of drugs), as well as how drugged you are (which considers Trip Control and your Meditation level) when on the nav screen or on the logout screen.
You can control the settings for each universe, including different levels of meditation and whether you have trip control or not.
