Adderall and caffeine are stimulants that increase alertness and focus, but they differ in potency, mechanism, and safety. Adderall, a prescription medication containing amphetamine salts, is used to treat ADHD and narcolepsy, offering strong, targeted cognitive and energy effects. Caffeine, a widely used over-the-counter stimulant, provides milder, short-term alertness and increased focus. Adderall carries higher risks of dependence, heart problems, and anxiety, while caffeine’s side effects are usually milder, such as jitteriness or insomnia. Both should be used responsibly, but Adderall requires medical supervision, whereas caffeine is generally safe in moderate amounts.
