President Trump has issued an executive order to speed up reviews into psychedelic drugs like psilocybin, LSD, and Ibogaine. Psychedelics are banned in the US in the vast majority of circumstances, but scientists are looking at the drugs and their possible therapeutic benefits for serious mental health conditions.

Ibogaine comes from a shrub native to west Africa and is used ceremonially in Gabon. Trials have reported benefits from the drugs in conditions like post-traumatic stress disorder and opioid addiction. But experts say that it’s been difficult to study because it can cause heart problems.

BBC’s Bernd Debussman Jr in Washington tells us more about the growing interest in psychedelics in the US. Plus, we hear about the reaction in Gabon from Yann Guignon, a researcher at Blessings Of The Forest, a charity that works to protect Gabonese cultural heritage.

Tourism is a vital part of the economy for many Caribbean nations, from Jamaica to Grenada to the Bahamas. In fact, the United Nations says the Caribbean is the region of the world that’s most dependent on tourists. The sector supports millions of jobs — from barmen and waiters to cab drivers and chefs — and many of these roles go to women and young people. But what happens when developers close off beaches to locals?

BBC reporter Chelsea Coates, who has visited several Caribbean islands, explains the growing tensions across the region as countries try to balance tourism with the rights and interests of local communities. Focusing on Barbuda, a tiny island with just a few thousand residents, she looks at the impact of major developments and how local residents are reacting.

Prediction markets Kalshi and Polymarket allow people to make trades against future events - which can range from when the US and Iran might sign a permanent peace deal and sports results, to whether a politician will mention a certain phrase in a speech. These sites have surged in popularity over the past year, hosting more than $44 billion in trades.

But they bring up all sorts of ethical questions. Not just war profiteering, but also insider trading. Recently a US soldier was arrested for allegedly using classified information to place bets on the capture of Venezuelan president Nicolas Maduro - before it happened. Reports say he won more than $400,000 from these bets.

And there are dozens of lawsuits at the US state level trying to figure out how to regulate these platforms. Minnesota has just become the first state to ban prediction markets.

So, why are people betting on things like the weather, elections and global conflicts - and should it be allowed? The BBC’s Madeline Gerber, who’s based in Washington explains.
