This is true, and the same is true of other stimulants in ADHD sufferers. For example, it ticks a box in ADHD diagnosis if a patient reports having had a paradoxical reaction to cocaine (drowsiness, focus, a feeling of quietness), because although the pharmacology is, to say the least, not as precise when compared to e.g. lisdexamfetamine, the impact is the same: both block the reuptake of dopamine in the brain.
