In brief: Adderall (dextroamphetamine and racemic amphetamine) or xr
Depends on if you take regular Adderall (dextroamphetamine and racemic amphetamine) or Adderall (dextroamphetamine and racemic amphetamine) xr. The xr may take a little longer to kick in, but lasts longer. Either way you should notice some benefit within an hour, but may take longer before the full effect.

In brief: 30-45 minutes
It usually takes between 30 and 45 minutes before the effect of Adderall (dextroamphetamine and racemic amphetamine) begins, if the dose is sufficient for you.
