Day Tripper (perk)

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

Effects
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.

Behind the scenes

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