Gum Drops

 are a food item found in Fallout 3. It can restore some of your Hit Points and causes no Radiation poisoning, but they are very rare. While it seems odd that the box says Radioactive Gumdrops and do not irradiate you, gumdrops actually provide radiation, but less than 1 rad per package. Since the in game description will only show whole rads, the game rounds down and displays no radiation at all.

Known Locations
At A Quick Fix in Rivet City. It must be stolen from the shop and does not appear to be for sale in the owner's inventory.

In the Jury Street Metro Station area (see Dead Man's Signal).

James Hargrave and C.J. Young carry them, they can be pickpocketed. Only with high Luck may they also carry bubblegum.

In the Vault Theme for your Megaton house; one appears on the shelf with the food in.
