A pillbox of mind-altering chems. Increases memory related functions, and speeds other mental processes. Highly addictive.In-game description, Fallout

Mentats are a brand of nootropic chems in Fallout, Fallout 2, Fallout 3, Fallout: New Vegas, Fallout 4, Fallout 76, Fallout Tactics, and Fallout: The Board Game.


The chalky red tablets manufactured by Med-Tek Laboratories were a popular recreational drug before the Great War, favored by consumers for their effect on creativity.[1][2] The active ingredient is a powerful nootropic that increases memory-related functions, and speeds other mental processes.[3] Students and those in other fields requiring intensive thought would also take Mentats for its mental benefits, but Mentats would gain a reputation as being a drug for beatniks and armchair philosopher.[4][5][6] The effect of Mentants is temporary, leaving the user tired and sluggish once it wears off. The drug seems to have a profound effect on a developing adolescent mind, which results in a permanent and noticeable intelligence increase.[7][8] Mentats can further be used by those suffering from Alzheimer's disease to curb the degeneration of mind and keep the user sharp and lucid when they would otherwise be delirious and unattentive.[4] However, excessive consumption could also result in health complications, including recurring migraines from withdrawal and even worsening or developing debilitating neurological disorders.[9][10]

Coupled with a high addiction rate, Mentats were and still are a double-edged sword.[3] However, the high addiction rate of Mentats was of no concern to Med Tek and was designed as such. Med Tek would practice pre-seeding areas it planned on selling to with free drugs to further drive sales of Mentats brand (as well as its Fixer brand of addiction cure).[11] The seeding of areas predominantly targeted school districts, such as Shaw High School, where Principal Ronald Tanner would use both Rusty Burton and the book return system[12] to distribute Mentants around Shaw High school. To further target children, Med Tek started developing enticing fruit-flavored varieties and offering them as prizes to win at the National Archives after completing a basic history quiz.[13][14]

Mentats packages (available both as cardboard packs and tins)[15] sold well, with their popularity surviving the Great War and making them a popular drug across the wasteland. Some chemists even figured out how to iterate on the design and create special blends of Mentats.[16] The professor from Broken Hills allegedly developed an easy method to mass-produce Mentats, likely owing to its ubiquitous nature across the country, even years after production ceased.

Mentats are most useful for characters with low Intelligence and Perception, as they grant a useful bonus for both these SPECIAL stats. The downside is that they are addictive.

Behind the scenes

The name "Mentats" is a reference to Frank Herbert's novel Dune, as in the wake of humanity rejecting artificially intelligent computers and robots, "Mentats" are humans trained for computer-like mathematical and logical computations. Mentats can consume Sapho Juice to increase their intellectual capabilities. After repeatedly consuming Sapho Juice the lips are permanently stained a deep ruby or cranberry color.


  1. Fallout 2 Official Strategies & Secrets p. 74: "This party drug was once favored for the boost it gave to creativity—tune in, turn on, drop out. Mentats are just the ticket when you need to figure out something particularly perplexing or impress someone with your wits and charm. Mentats also sharpen your Perception, which greatly enhances long-range sniping attacks."
  2. Doctor Mobius: "I have such science-arific ideas while those chalky tablets are zipping through my biogel!".
