America’s cannabis industry is worth tens of billions of dollar and it generates tax revenues and jobs. But it is barred from accessing most financial services. This is because, while legal in an increasing number US states, cannabis remains illegal at a federal level. We hear what it’s like running a cannabis business from Ken Churchill of the West Coast Cannabis Club in California. Emily Dufton, author of Grass Roots: The Rise and Fall and Rise of Marijuana in America, explains how the US went from "Just Say No" in the 1980s to yes now. And Robert Hoban, a lawyer who specialises in cannabis, explains why two currently empty Georgia Senate seats could determine whether the Biden administration can fulfil its pledge to decriminalise cannabis.

Artificial intelligence is increasingly part of our daily lives - in health, in transport, entertainment and much more - but how many of us actually trust the algorithms that drive it? Rolls-Royce says it’s now developed a system, called the Aletheia framework, that gives IT engineers in any sector a way of testing whether their AI systems are making decisions that are safe and trustworthy. The aerospace company says it's making the framework available for free to all. Manuela Saragosa speaks to Caroline Gorski from Rolls-Royce who helped develop the Aletheia framework. She also speaks about AI's trust issues with Dame Wendy Hall, Professor of Computer Science at the University of Southampton in the UK and Chair of the Ada Lovelace Institute.

Britain is looking to ban the export of live animals for slaughter and fattening after its existing trade arrangement with the European Union lapse at the end of this year. Natasha Smith of Compassion in World Farming, who have campaigned on this for decades, explains why they’re against the practice. Meanwhile UK minister Craig Mackinlay says leaving the EU’s trade rules after Brexit is key to getting the ban implemented. But will the ban run afoul of WTO free trade rules? Emily Rees of consultancy Trade Strategies breaks down the rules and whether the ban fits. But what do UK farmers think? Phil Stocker of the National Sheep Association says this ban overshoots, and puts farmers already in an unclear position because of Brexit, even more on the back foot. And Francesca Porta of the Brussels-based Eurogroup for Animals explains what changes might be coming in the EU itself on live animal transport.

Boris Johnson's dinner with EU chief Ursula von der Leyen - aimed at breaking the Brexit trade deadlock - has ended without agreement. The BBC's Laura Kuenssberg said the evening had "plainly gone badly" and the chances of the UK leaving the post-Brexit transition period at the end of the year without a firm arrangement was a "big step closer". What would that mean for the UK, and the rest of the world? Joining the programme live will be BBC World Service political correspondent Rob Watson, and Dr Anna Jerzewska, Director of the trade consultancy Trade and Borders.

A UK grandmother became the world’s first recipient of the Pfizer Covid vaccine this week. What does this mean for the pharmaceutical industry?

We’ll hear from former Pfizer executive John Lamattina, Thomas Cueni of the International Federation of Pharmaceutical Manufacturers, Tahir Amin of the Initiative for Medicines, Access & Knowledge, as well as Sudarshan Jain, Secretary General of the Indian Pharmaceutical Alliance.

It was grounded worldwide after two tragic accidents. Now, regulators in the US have given it permission to fly again – but will it really be safe? Theo Leggett speaks to Mark Pegram whose son Sam was killed aboard the flight which crashed after take-off from the Ethiopian capital Addis Ababa in March last year. He also spoke to Ed Pierson, a former senior manager on the 737 production line at Boeing’s Renton factory, just outside Seattle, who gave testimony to the House of Representatives saying how months before the first accident, he had emailed his bosses, warning them how the pressure to produce new planes as fast as possible was undermining safety. In response to Mr Pierson’s testimony, Boeing insisted that the suggestion of a link between his concerns and the Max accidents was completely unfounded. It added that none of the authorities investigating the accidents had found that production conditions in the 737 factory had contributed in any way.The US regulator, the Federal Aviation Administration, has also come under fire. Barry Valentine, a former assistant administrator at the FAA who now works as a consultant for the Wicks group, says lessons have been learnt. Also in the programme is attorney and former inspector general of the US department of transportation, Mary Schiavo. And Bjorn Fehrm, of aviation consultants Leeham, who insists the 737 Max will now be safe.
