Known to the Greeks as opos or opion, as afiun in Persian and Arabic, and fuyung in Chinese, opium is at once a palliative and a poison.

Pierre-Arnaud Chouvy reveals the long and fascinating history of a powerful and addictive drug and explores the changing fortunes of the modern-day illicit opium trade, especially in the remote regions of Asia.
