Johann Hari spent three years and traveled roughly 30,000 miles researching Chasing the Scream, a 2015 book arguing that the war on drugs was built on bad science and worse politics, and that the real opposite of addiction isn't sobriety, it's connection. It's a genuinely gripping, well-reviewed book that became a New York Times bestseller and later inspired the film The United States vs. Billie Holiday. It's also written by a journalist who resigned from a major newspaper in 2011 after admitting to plagiarism and fabricating quotes. Most reviews of this book skip that fact entirely or bury it in a footnote. This one won't, because it directly affects how much weight you should put on Hari's reporting, and readers deserve to know it before they buy the book, not after.
What Chasing the Scream Actually Is
The book opens, unexpectedly, with the story of Billie Holiday and Harry Anslinger, the first head of the US Federal Bureau of Narcotics, using their intertwined history to trace the origins of American drug prohibition back to a specific man's personal crusade rather than a purely evidence-based policy. From there Hari travels widely -- to Arizona drug courts, to a legal marijuana operation in Colorado, to Portugal to examine its decriminalization model, to Vancouver's harm-reduction programs -- interviewing addicts, dealers, police officers, scientists, and policymakers along the way. The throughline is a specific, provocative claim: that the standard chemical-hook model of addiction (the idea that certain drugs simply hijack the brain and create dependency on contact) is incomplete, and that isolation, trauma, and disconnection from community are much bigger drivers of addiction than the drugs themselves. Hari leans heavily on Bruce Alexander's "Rat Park" experiments, in which rats housed in a rich, social, stimulating environment showed far less interest in a morphine solution than isolated rats in a bare cage, as the scientific anchor for his broader argument.
About Johann Hari and Why He Wrote This
Hari is a British journalist, born in 1979, who spent nine years as a columnist for The Independent in London and was twice named Newspaper Journalist of the Year by Amnesty International UK during that run. His stated motivation for the book is personal: one of his earliest memories is of trying and failing to wake a relative who couldn't be roused, and as he got older he understood addiction was present in his own family. That unresolved, personal confusion is what he says sent him on the three-year global research trip that became this book, trying to answer, for himself as much as for readers, what actually causes addiction and what actually treats it.
It's also necessary to state the rest of Hari's record plainly, because it happened in the same decade and shapes how this book should be read. In 2011, Hari resigned from The Independent after admitting he had plagiarized passages from other publications without attribution, embellished interviews by inserting quotes his subjects hadn't actually said, and used a pseudonymous Wikipedia account to make malicious edits to the pages of journalists who had criticized his work. Chasing the Scream was published four years after that resignation, positioned by Hari and his publisher as a return to serious, deeply reported nonfiction. Whether it fully earns that trust is something readers have to weigh for themselves, and the section below on where reviewers pushed back covers exactly why that question keeps coming up.
How It Compares to Lost Connections
Hari's later book, Lost Connections, applies the same basic thesis -- that disconnection, not just brain chemistry, drives psychological suffering -- to depression and anxiety instead of addiction. If you found the "connection matters more than we're told" argument compelling here, Lost Connections extends it into different territory, though it inherited the same credibility scrutiny given Hari's history. Readers who want the throughline of Hari's overall body of work should know both books share this identical tension: a genuinely interesting, research-adjacent thesis delivered by a narrator whose past conduct means every anecdote deserves a slightly more skeptical read than it would from a writer without that record.
What Critics Actually Said
The New York Times called the book "a testament to Hari's skill as a writer," and it became a New York Times bestseller, with strong praise circulating for its narrative drive and the boldness of its central argument against decades of prohibition-era drug policy. Reviewers consistently credit Hari with genuine storytelling skill -- the Billie Holiday and Harry Anslinger material in particular gets singled out as gripping, well-constructed narrative nonfiction, and it's the section of the book that later became the basis for a feature film. The book's reception, taken as a whole, was praise for narrative drive and policy critique, sitting alongside real, documented criticism for selective evidence and overreliance on anecdotes -- both things were true of the same book.
And the aggregate reader picture, for what it's worth:
Where Real Reviews Pushed Back
This is the section that matters most for this particular book, and it goes beyond ordinary literary criticism. Hari's prior journalistic scandals -- plagiarism, fabricated quotes, and pseudonymous online attacks -- have prompted real, documented skepticism about the veracity of the interviews and stories reported in Chasing the Scream. One detailed independent review found that when you follow the book's footnotes back to the actual cited interviews, they don't always support what the text claims, and in some cases provide no clear evidence for the claims attributed to them. Separately, Noam Chomsky publicly accused Hari of what he called "idiotic fabrications" regarding statements Hari attributed to him, specifically a false claim that Chomsky denies the Cambodian genocide -- a claim Hari has since said he regrets and has personally apologized to Chomsky for. None of this means every fact in the book is wrong. It does mean that a writer with this specific, documented history of embellishment and fabrication is not the ideal narrator to take entirely on faith, and any responsible review of this book has to say so directly rather than treating it as background trivia.
On the Rat Park Argument and Why It Still Matters
Separate from Hari's own credibility, it's worth noting that the book's central scientific anchor -- Bruce Alexander's Rat Park experiments -- is real, independently conducted research that exists outside of anything Hari personally reported. The finding that socially and environmentally enriched rats showed dramatically less interest in an addictive substance than isolated, caged rats is a genuine, citable data point in addiction science, regardless of how Hari chose to narrate around it. That's useful context: the book's underlying thesis, that environment and connection shape addiction risk more than pure chemistry does, has support that doesn't depend on trusting Hari's own reporting. What readers should be more cautious about is the specific anecdotes, interview quotes, and secondhand stories Hari uses to dramatize that thesis, which is precisely where the documented credibility concerns above apply.
On the War on Drugs, Portugal, and Policy Alternatives
The book's later chapters, covering Portugal's decriminalization model and various harm-reduction programs, are its most policy-focused and, for many readers, its most persuasive. Portugal's approach -- treating drug use as a health issue rather than a criminal one, paired with investment in social and economic reintegration -- is documented by outside sources beyond this book, giving that section a firmer independent footing than some of the more personal, anecdote-driven chapters elsewhere. If you're reading Chasing the Scream primarily for its policy argument about decriminalization rather than for its individual human-interest stories, that's arguably the more defensible way to read it, given everything above.
Key Takeaways
- Hari's core thesis -- connection, not just chemistry, drives addiction -- is backed by real, independently verifiable research including Alexander's Rat Park experiments
- Hari's 2011 resignation over plagiarism and fabricated quotes is a matter of public record and directly relevant to how much trust to extend his individual anecdotes
- Independent reviewers who checked footnotes against source interviews found inconsistencies in some cases -- read the specific human-interest stories with appropriate caution
- The Portugal and policy-focused chapters rest on firmer, more externally verifiable ground than the book's individual character-driven narratives
Who This Book Is Actually For
Readers who want a fast-moving, well-written introduction to alternative theories of addiction and drug policy, and who are willing to treat specific anecdotes with healthy skepticism while engaging seriously with the book's broader, independently supported thesis. It's a genuinely useful entry point into a complicated topic, provided you read it as a persuasive essay rather than a fully verified investigative record.
Who Should Read Something Else Instead
If accurate sourcing and verified reporting matter more to you than narrative pace, Hari's documented history is a real reason for caution, and you may prefer to go directly to Bruce Alexander's own published Rat Park research or to journalists without a comparable credibility record for the same subject matter. Readers who want Hari's later application of a similar thesis to depression and anxiety, with the same caveats in mind, might look at Lost Connections next.

Frequently Asked Questions
Did the author of this book really get caught plagiarizing?
Yes, and it's a matter of public record. Johann Hari resigned from The Independent in 2011 after admitting to plagiarism, fabricating and lifting quotes in interviews, and making malicious anonymous edits to the Wikipedia pages of journalists who had criticized him. That history predates Chasing the Scream and is worth knowing before you read it.
What's the actual Goodreads rating?
Around 4.5 out of 5 from thousands of ratings as of this writing, per Goodreads — an unusually high average for a nonfiction book. Check the live number yourself, since it will keep moving.
Has anyone fact-checked the specific claims in this book?
Yes, and the results are mixed. Independent reviewers who followed the book's footnotes back to its cited interviews found that some sources didn't fully support the claims made in the text, and Noam Chomsky publicly disputed how Hari characterized comments Chomsky made about the Cambodian genocide — a claim Hari later said he regretted and apologized for.
Is the book's central argument still worth engaging with?
Many readers and reviewers think so — the core idea, that connection and social environment matter more to addiction than raw chemical hooks, draws on real, independently verifiable research by other scientists, including Bruce Alexander's Rat Park experiments. The concern raised by critics is less about the underlying thesis and more about whether every anecdote and quote Hari uses to support it holds up.

Final Verdict
Chasing the Scream is a genuinely well-written, ambitious piece of narrative nonfiction with a thesis that's more scientifically defensible than most drug-war-era assumptions, and its high reader ratings and New York Times praise are real and earned on craft alone. It's also written by a journalist with a documented, public record of plagiarism and fabrication, and independent fact-checkers have found real gaps between the book's footnotes and what they actually support. Read the big idea seriously. Read the specific anecdotes with a more skeptical eye than you'd give most nonfiction, and you'll get real value out of this book without getting misled by it.
