The isomers in adderall are dextroamphetamine and levoamphetamine. They are both “amphetamine”.
Last I checked it’s a racemic mixture, so it’ll be 50/50 levo/dextro.
Fun fact! Certain SKUs of Vicks inhalers use levomethamphetamine as a very effective decongestant. It’s literally methamphetamine! Just not the kind that can get you even remotely high.
