> and the entire value of the drug is in the measurements. I'm not sure this is true. While modern Adderall has a closely controlled mixture of multiple enantiomers, it hasn't always been this way. Medicine historically didn't care nearly as much about racemic mixtures, and the possibility of stereo toxicity (eg Thalidomide). Many drugs in modern human history, including mixed amphetamine salts, have been marketed with very little concern for racemic purity.
