Whiskey Rose

 is a perk in Fallout: New Vegas given to you when Cass is your companion.

The Whiskey Rose perk lets you consume whiskey and not have any adverse side effects or addictions, while raising your damage threshold by +3 DT.


 * Perk description states that the player ignores the negative effects of alcohol addiction. It is still possible to become addicted to whiskey but you do not suffer any penalties.
