[Barba Jacob and the history of marihuana]

The outstanding Latin-American poet Porfirio Barba-Jacob (1883-1942) was a heavy user of marihuana. In this paper the author provides some data concerning historical antecedents of marihuana--mainly in Latin America--and he discusses its influence upon Barba-Jacob's life and poetry. The hypothesis that consumption of marihuana is used by some hyperkinetic adults as self-induced pharmacotherapy is outlined.
