NOW WITH A NEW AFTERWORD, THE NEW YORK TIMES BESTSELLER AND THE SOURCE OF THE VIRAL TED TALK.

What if everything we've been told about addiction is wrong? One of Johann Hari's earliest memories is of trying to wake up one of his relatives and not being able to. As he grew older, he realised there was addiction in his family.

Confused, he set out on a three-year, thirty-thousand mile journey to discover what really causes addiction - and how to solve it. Told through a series of gripping human stories, this book was the basis of a TED talk and animation that have been viewed more than twenty million times. It has transformed the global debate about addiction.
