According to Drugs.com, the effects of Adderall last four to six hours:
“When taken as prescribed, the effects of Adderall (amphetamine and dextroamphetamine) last for about 4 to 6 hours. The effects of Adderall XR last for up to 12 hours because this form of Adderall has been designed to release its contents slowly, over a longer period of time (this is called a sustained release preparation).”
