David Gillespie, one of Australia’s best-selling Authors, is back and this time we talk about the potential relationship between ADHD and addiction, how quickly we become adapted to certain drugs (and need more and more), the drugs used (and supplied by governments) during the first and second World Wars to ‘keep the soldiers focused’ (amazing stuff), why breaking an addiction is so difficult (which most non-addicts don’t understand), what happens to us when we don’t get enough dopamine, when Australia used more cocaine than any other country in the world (per capita) and lots more.
