- After Burner gum can be found on civilians in Macomb.
- A deceased Vault 0 citizen in Peoria.

The effects of the After Burner gum are identical to that of jet in Fallout 2, except that After Burner gum gives a temporary addiction rather than a permanent one without a cure, and it is much rarer and more valuable.
Behind the scenes
After Burner Gum was planned for inclusion in Van Buren.
