The follow-up to the widely praised Opium, In The Arms of Morpheus is the shocking story of how a simple but bewitching substance, touted as a miracle drug, enslaved unwitting generations of 19th century writers, artists and ordinary citizens. Extracted from opium, the sap of the poppy, this popular drug was welcomed into the homes of rich and poor alike, in the guise of medicinal uses in the form of laudanum and opium elixirs, and as pure, undisguised morphine.

Laudanum contained opium, saffron, cinnamon and alcohol. In the spirit of 19th century progress, other opium concoctions were created and a whole industry in quackery erupted. In both Britain and North America, opium was mixed with everything imaginable: mercury, hashish, cayenne pepper, ether, chloroform, belladonna and whisky, sherry, wine and brandy.
