What are the best stimulants for productivity?

I read this article from an American doctor whose residency students couldn't keep up with him.
His secret was to use cocaine and morphine, with cocaine he could possibly stay awake and with morphine he could focus his thoughts.

Does anyone know of easily accessible stimulants that help improve productivity?
