A FOAF has somehow managed to come upon approximately 5,000 GSK Dexedrine tablets (imprint codes checked through RxList), don't ask how. Not being the type of person who enjoys swallowing pills, he was wondering what would be an effective way to separate most of the binders/inactives to give him a product of reasonable purity which he could snort.
RxList shows that Dexedrine contains, in addition to d-amphetamine: calcium sulfate, FD&C Yellow No. 5 (tartrazine), FD&C Yellow No. 6, gelatin, lactose, mineral oil, starch, stearic acid, sucrose, talc.
Any idea?
