It is now one hundred years since drugs were first banned -- and all through this long century of waging war on drugs, we have been told a story about addiction by our teachers and by our governments. This story is so deeply ingrained in our minds that we take it for granted. It seems obvious. It seems manifestly true. Until I set off three and a half years ago on a 30,000-mile journey for my new book, , to figure out what is really driving the drug war, I believed it too. But what I learned on the road is that almost everything we have been told about addiction is wrong -- and there is a very different story waiting for us, if only we are ready to hear it.
