This collection of essays explores the complex and contested histories
of drugs and narcotics in societies from ancient Greece to the present
day. It shows that the major substances so used, from herbs of the field
to laboratory-produced synthetic medicines, have a healing potential,
and have been widely employed both within and outside the medical
profession. Many of these substances, if taken improperly, are also
highly toxic or even lethally poisonous. Some, being mood-influencing
and habit-forming, are open to abuse and lead to addiction and are even
objects of international contraband trade and the targets of "drug
wars."
