Few people have done more to bring honest, evidence-based thinking about drugs to a wider audience than Professor David Nutt. This collection of archive lectures covers a broad range of topics, from how alcohol and other drugs affect the brain, to addiction, mental health, and why drug policy so often gets the science wrong. They're free to watch, evidence-led, and as relevant today as when they were recorded. If you've ever wanted to understand the real science behind drugs, this is a great place to start.
