Publisher's Description: While there have always been norms and customs around the use of drugs, 
explicit public policies--regulations, taxes, and prohibitions--designed
 to control drug abuse are a more recent phenomenon.  Those policies 
sometimes have terrible side-effects:  most prominently the development 
of criminal enterprises dealing in forbidden (or untaxed) drugs and the 
use of the profits of drug-dealing to finance insurgency and terrorism. 
Neither a drug-free world nor a world of free drugs seems to be on 
offer, leaving citizens and officials to face the age-old problem:  What
 are we going to do about drugs?
In 
Drugs and Drug Policy, three noted authorities survey the subject with exceptional clarity, in this addition to the acclaimed series, 
What Everyone Needs to Know.
  They begin by, defining "drugs," examining how they work in the brain,
 discussing the nature of addiction, and exploring the damage they do to
 users. The book moves on to policy, answering questions about 
legalization, the role of criminal prohibitions, and the relative legal 
tolerance for alcohol and tobacco. The authors then dissect the illicit 
trade, from street dealers to the flow of money to the effect of 
catching kingpins, and show the precise nature of the relationship 
between drugs and crime. They examine treatment, both its effectiveness 
and the role of public policy, and discuss the beneficial effects of 
some abusable substances. Finally they move outward to look at the role 
of drugs in our foreign policy, their relationship to terrorism, and the
 ugly politics that surround the issue.
Crisp, clear, and comprehensive, this is a handy and up-to-date overview of one of the most pressing topics in today's world.
