Adderall & Focalin are both C-II medications, but Adderall is a stronger CNS stimulant than Focalin. Adderall is an amphetamine. Focalin is the brand name for the drug dexmethylphenidate. Focalin is a "pure" version of Ritalin (methylphenidate), containing only the active isomer. Adderall & Focalin both last for a duration of 4-6 hours (3-4 hours for some users).
