Jet antidote is a chem and an important part of the power struggle between Vault City and New Reno over Redding which, comes about as a result of the quest, Find some endorphin blockers to make a cure for Jet.
It is offered for sale by different merchants in San Francisco, but only after the cure is discovered.
Deliver a sample of jet to Dr. Troy: When the Chosen One 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 Chosen 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 them to use jet anytime they want without fear of addiction.
- The antidote can be used on Myron. In this case, however, it will be consumed.
- If one doesn't find the right track to find the cure they can get it from the gun merchant on the PMV Valdez, who (curiously) carries almost no guns but loads of drugs, plus has several vials of jet antidote which are replenished if one buys them.
- Discovering the cure throws a wrench in Mordino's plan to take over Redding. It also ensures that Redding joins forces with Vault City in the ending.
