Legitimate cognitive enhancers like caffeine and nicotine are widely accepted in society and legally accessible without prescription. They are commonly used to increase alertness, concentration, and energy—particularly in work and academic settings. Despite their psychoactive effects, these substances are normalized through cultural habits, such as drinking coffee or using nicotine products, and are rarely questioned from an ethical standpoint.

Legitimate Cognitive Enhancers 

Illegitimate cognitive enhancers refer to prescription drugs (PCEs)—such as modafinil, Adderall, or Ritalin—used off-label by healthy individuals to improve focus, memory, or mental stamina. Though often more potent than common stimulants, their use outside of medical supervision is socially controversial and legally restricted. These enhancers raise ethical concerns around fairness, coercion, and authenticity, and are often viewed as unnatural or performance-cheating despite their functional similarities to accepted substances.
