Pure Amphetamine Extraction

What is the best way to extract pure freebase amphetamines from Adderall? I have ALOT of Adderall to work with (as in 60 20mg pills per month), so that is far from the issue. I just need to good extraction method.

 

I tried everything as a kid with those...quite a kitchen chemist too and i couldnt figure out shit....

 

I used to stir vyvanses in with this trypsin enzyme n heat it a lil to get seperate the protein bonded to the amphetamine but with straight dextro addy I'm not sure. Iso?

 

I want to make it into smokable form. So freebase i presume,

 

I recommend reading up on ol' uncle fester
Clandestine Amphetamine Manufacturing techinques or somethign

 

iso, bring it back to HCI with muratic acid..
