The Mystique of Opium [EPUB ebook] 

Opium used to have the same importance in international economy and state-led strategies as petrol has today. It became the basis for trade with isolationist China as soon as the Opium Wars obtained trading rights for Western Companies. International strategies for personal reveries… 19th-century European writers were to begin praising this “midnight fairy”. This book offers a tastefully illustrated history of this toxic substance, its paraphernalia and era.
