Day Tripper is a challenge perk in Fallout: New Vegas.


You've done enough chems to know how to hang on to the effects just a while longer. More specifically, ingested chems last 33% longer than they normally would. This perk stacks with the Chemist perk. Chems are first increased by 33% with Day Tripper, then doubled with the Chemist perk.


  • If you have both Chemist and Day Tripper, all consumable foods have their times increased. For example, the effects of brahmin meat normally last for 15 seconds; with these two perks it increases the duration up to 40 seconds.
  • The increased duration of healing items does not show up in the list of effects for the items on the Pip-Boy.

Behind the scenes

  • The perk name is a reference to The Beatles' song by the same name.
