Jet antidote

Jet antidote is a consumable in Fallout 2. It cures the addiction effects of Jet.

Characteristics
Jet antidote is a chem in Fallout 2. It is an important part of the power struggle between Vault City and New Reno over Redding, and comes about as a result of the Find some endorphin blockers to make a cure for Jet quest.

Quests
Deliver a sample of jet to Dr. Troy: when the player manufactures the cure, Dr. Troy gives them two vials of the antidote, one of which is passed on to Doc Johnson in Redding to cure the miners of their jet addiction. The player is free to keep the second vial for themselves. The jet antidote is unique in that it can be used an infinite number of times without being consumed, effectively allowing the player to use jet anytime they want without fear of addiction. Players who use the unofficial patch, however, do not enjoy this bug: you must continue to buy more in San Francisco.

Locations
It is offered for sale by different merchants in San Francisco, but only after the cure is discovered.
