Bad Pharma is the latest book by the well-known anti-quackery campaigner Ben Goldacre, and attempts to explain to us that medicine is broken. Despite the title, he criticises not only the pharmaceutical industry, but also regulators, doctors, academic clinical researchers, ethics committees, and various other players in the world of clinical research. His take home message (I don't think a spoiler alert is really needed here!) is that we simply can't trust the evidence that we see about the efficacy and safety of drugs in common use.
