I'll just very simply re-state the opinions/questions/assumptions that I made originally, since there has certainly been some misunderstanding.
DEXTROamphetamine is the active enantiomer of amphetamine. That means it works anywhere from a little to a whole heck of a lot better than levoamphetamine, depending on enzyme selectivity. In the case of this chemical, biological selectivity for the d form is high. THEREFORE, dextroamphetamine is going to be a lot more effective, gram for gram, than levoamphetamine. Simple, and lots of hard science to back it up so we know that it isn't something like placebo effect. I never questioned this, and while Iago's rant on the efficacy of dextroamphetamine versus chimeramphetamine was certainly entertaining, it wasn't very illuminating.
MY QUESTION was over the claim which has been made here numerous times that LEVOamphetamine is a PNS stimulant, rather than merely being less effective than dextroamphetamine or a biochemically inert substance. It was this assumption that I was contesting, as I've found zero evidence to back it up.
Anyone else have anything useful to contribute? :)
