Most of us think we know cocaine — a glamorous party drug with a dark side, a scourge of the 80s, a straightforward villain in the story of addiction. But what happens behind the scenes - in the months of work and miles of travel that take the coca leaf of Central and South America to the consumers all around the world?

Emilia Ziosi is a researcher and science communicator whose work has focused largely on the cocaine trade.

In this episode, Zale and Emilia dig into the assumptions we carry about cocaine and where they actually come from, including:

- How cocaine was used medically for decades — and why that history got buried

- What's actually happening in the brain during cocaine use, and why the "addiction = weak willpower" framing misses the point

- The racial politics behind cocaine prohibition and how moral panic shaped drug policy

- Why cocaine's cultural image has shifted so dramatically across time and class

- What harm reduction gets right that abstinence-only approaches keep getting wrong

- Whether we're asking the right questions when it comes to drug policy reform

What does it actually mean to thrive—not emotionally, but biologically? In this episode, neuroscientist Paul Zak breaks down the brain science behind emotional fitness, social connection, and the kinds of experiences that make life feel deeply engaging rather than merely comfortable. We explore whether thriving is a measurable state of the nervous system, why modern life may be quietly working against it, and how factors like immersion, awe, and human connection shape the way our brains function over time.

In recent years, conversations around sex have become far more attentive to women’s experiences, desires, and frustrations — and for good reason. But in the process, have we stopped talking honestly about male sexuality? In this episode, Zale sits down with sex therapist and author Chris Donaghue to explore the psychology of male sexual performance, insecurity, validation, and desire. From penis size and performance anxiety, to casual sex, long-term relationships, and what actually makes someone “good in bed,” this conversation examines the fears men rarely admit out loud — and asks what healthy male sexuality could look like without shame, pressure, and distorted expectations.
