Erythroxylon coca
"...I sneered at the poor mortals condemned to live in this valley of tears while I, carried on the wings of two leaves of coca, went flying through the spaces of 77, 438 words, each more splendid than the one before...An hour later, I was sufficiently calm to write these words in a steady hand: God is unjust because he made man incapable of sustaining the effect of coca all life long. I would rather have a life span of ten years with coca than one of 10 000 000..(and here I has inserted a line of zeros) centuries without coca..."
