Sotoxi

Sotoxi is the brand of cigarettes in Doom 3. Cartons of them are found throughout the game in storage lockers, by equipment and ammunition, and by cola cans and empty burgerboxes.

A Sotoxi is equivalent to a full-strength, short cigarette. The computer-station guards love to smoke Sotoxis while drinking their coffee and eating stolen medication from the medical labs. The chaingun commandos can be caught smoking a Sotoxi just as they walk out from a red-lite storage closet.
