I haven't found too much info on propylhexedrine on the web (not surprising, given it's only used in one medication anymore), but Wikipedia appears to have conflicting information. On the main Benzedrex page they say: http://en.wikipedia.org/wiki/Benzedrex *BUT* on the page for Benzedrine, they say: http://en.wikipedia.org/wiki/Benzedrine Huh... hexahydromethamphetamine? So, is propylhexedrine an amphetamine or not? Or is it more a matter of semantics? I am not a chemistry-head so he could be waaaayyyyy off on that latter assumption. Anyway, thanks for anyone who can clear this up (although I am satisfied to assert that the propyl high *feels like* an amphetamine in most respects).
