> That was Dextroamphetamine or “Green Hornets” as they were more commonly referred to by the troops.
That’s also true, I had forgotten about Green Hornets — Dextroamphetamine was also used by James Bond in several of Ian Fleming’s novels. He called them “Benzedrine tablets”.
Methamphetamine is slightly different to Dextroamphetamine, with much the same effects and similar side-effects. Both are based on ephedrine, an extract from the ephedra plant.
Methamphetamine was invented for German soldiers in WW-II. Hitler apparently took it: if so, that can explain an awful lot.
