Pharmacology - Cleaning up (generic) adderall for snorting

[hamsterdam]

swim did a search and didn't really find too much about this..

so he has a few things he's wondering about:

The most simple:

Volume Reduction -- Is there an easy way to filter out the bulk of the binders/fillers with minimal loss of the amphetamines, just to cut down on the volume you have to snort

Still relatively simple:

How difficult would it be to do an acid/base, and end up with a relatively pure product free of any fillers/binders? Swim realizes this procedure would have to be done multiple times due to multiple salts. And if this is done.. what would be the 'best' salt to end up with? (Since this would be under your control)

and a complex one:

How would you go about converting the levo-amphetamine portion of adderall into dextro-amphetamine? Swim realizes this is probably out of his league though.
