This master work brings together in one volume all the texts on drugs written by the philosopher Antonio Escohotado and complements the historical approach with phenomenological by an appendix that examines the main drugs discovered, both legal and illegal. General drug history is a unique book in world literature for its precision and depth. This edition has been updated, reviewed and expanded. — “A fantastic amount of universal history understood in a very precise and well-organized work” (Richard Evans Schultes, Journal of Ethnopharmacology). — “A book without doubt unique in the bibliography not already European but world, for the amplitude and complexity of its purpose, as well as its depth. It encloses what its title offers and much more: a new phenomenology of consciousness” (Fernando Savater, El País). — ‘Aplainous deployment of data, quotations, tracks and a comprehensive development of arguments and reasons’ (Alberto Hernando, La Vanguardia). — “Without a doubt, the best book on drugs in our language […] A decollant work on the international scene” (Enrique Galan, ABC).
