Yep, both Adderall immediate-release and Adderall-XR contain d-amphetamine and l-amphetamine salts in a 3:1 ratio.
The thread thus far or Chemist have probably already explained, but the major difference between Adderall and Dexedrine is that Adderall ALSO contains racemic amphetamine, which is a 50/50 combination of dextroamphetamine and levamphetamine. These amphetamines are molecular mirror images or optical isomers. Levamphetamine, the L-isomer, is mainly a *cardiovascular system stimulator* rather than a cerebral stimulant. So, Adderall affects both the CNS (central nervous system) and PNS (peripheral nervous system).
If anyone would like to read more on Adderall visit the URL below. It points to the official prescribing information for the extended-release formulation. You will need the Acrobat Reader.
