Slasher

 is a consumable item in Fallout: New Vegas.

Characteristics
is made at a campfire, and requires a Science skill of 50. It essentially combines the effects of Med-X and Psycho into a single drug except it is possible to combine the effects of this drug with Med-X to gain a 50% boost to damage resistance. It will not stack with Psycho, therefore you can only get 25% damage bonus even you use both of slasher and Psycho.

 * Stimpak (2).

Locations
The only place that Slasher can be found in the wild is from Jack, in Red Rock Canyon, after teaching him the recipe.
