The findings of a new study suggest that children’s ADHD medications, such as Adderall and Ritalin, will not stunt their growth. The study followed three groups of children, one with ADHD taking stimulant medications, one with ADHD not taking medication, and one without ADHD and not on medication. The individuals were tracked from childhood through adulthood. At the conclusion of the study, the group taking ADHD medication did not show any difference in adult height from the other groups.
