Pack of cigarettes (Fallout 3)

A pack of cigarettes is a miscellaneous item in Fallout 3 and Fallout: New Vegas.

Characteristics
Packs of Big Boss brand cigarettes are abundant in both the Capital and Mojave wastelands, and can be found in many locations or purchased from merchants. Like other cigarettes, they can be traded but cannot be smoked by the player character.

Uses

 * As with all miscellaneous items, they can be used as Rock-It Launcher ammunition.
 * Packs of cigarettes may be exchanged for five Sierra Madre chips or purchased for 10 chips at a Sierra Madre vending machine, either in the Sierra Madre Casino & Resort itself or at the abandoned Brotherhood of Steel bunker.

Behind the scenes
The brand name "Big Boss" alludes to the popular stealth/action series Metal Gear and Metal Gear Solid. One of the primary characters in both series is code-named Big Boss, and is nearly always portrayed smoking.
