This book looks at the complex web that links people across the world - from the Afghan poppy farmer to the London heroin addict. The drugs trade is now a huge global industry - generating more income than the tourist industry - and this book looks at why this is so and the measures governments have taken to combat it. It presents the facts about the production, distribution and use of illegal drugs and asks how the supply and demand of drugs can be reduced. Throughout, there are debate boxes which challenge the reader to think about difficult questions and viewpoints boxes that look at differing sides of the debates.
