Direct Answer

Long-term Adderall use is associated with cardiovascular effects (elevated heart rate and blood pressure), appetite suppression and potential weight loss, insomnia, and psychological effects like anxiety or mood changes. In children, growth suppression has been documented — the MTA study showed an average of 2cm less height gain over 3 years. The most significant long-term concern is dopamine system changes: chronic stimulant use downregulates dopamine receptors, which can make it harder to feel motivated or experience pleasure without the medication.
