An increasing number of people are dying from misuse of synthetic opioids. In 2022, the US recorded over 70,000 overdose deaths involving synthetic opioids. The government is spending billions to combat the effects of these super strength drugs.
Synthetic opioids, such as Fentanyl, are made in laboratories by using materials derived from the opium poppy. China is a major hub for the production of synthetic opioids, where it then makes its way to North America through Mexican drug cartels.
The lab-made drugs can be more deadly than the natural materials, but they are more easily accessible, and prevalence is rising across the world.
In West Africa and the Middle East, tramadol is one of the most consumed synthetic drugs. The rise of synthetic opioids in the European market, which are being used as a substitute for a heroin shortage, is fuelling concern that these substances could lead to a rise in drug-related deaths.
This week on The Inquiry, we’re asking are synthetic opioids a global problem?

Six months into Israel’s war in Gaza and with no sign of a ceasefire or breakthrough in securing the release of the 130 hostages, as yet unaccounted for, pressure is mounting on Israel’s Prime Minister Benjamin Netanyahu.
There have been widespread protests in Tel Aviv and across Israel. There have been calls both from home and abroad for an early election to be called. And Israel’s greatest ally, the United States has sharpened its rhetoric in the past few weeks over Israel’s conduct of the war, with President Biden now saying that he believes Benjamin Netanyahu is making ‘a mistake’ in his handling of it.
For his part, the Israeli Prime Minister looks set to continue with his military offensive and has shown no indication so far that he is willing to step down or call an early election.
So, on this week’s Inquiry, we’re asking ‘How secure is Benjamin Netanyahu’s leadership?’

Multiple Sclerosis (MS) is a neurological disease which can lead to loss of mobility and vision. Almost 3 million people worldwide are affected by it. There is no cure, but attempts are being made to accelerate the healing process with treatments to restore what the disease has damaged.
At the same time, scientists have recently discovered a link between MS and a common virus that the majority of us carry in our bodies. It had been known for years that there was a link between Multiple Sclerosis and Epstein-Barr virus (EBV). But then, a study finally proved the link.
Now, trials are underway on potential vaccines against EBV and scientists are hopeful that this could be a gateway to preventing MS.
This week on the Inquiry we are asking: Are we close to a breakthrough for Multiple Sclerosis?

For centuries chocolate has had a global appeal, the key ingredient of this confectionery is derived from the dried and fully fermented seed of the Theobroma cacao, whose origins began in northern Amazonia. From this tree, both cocoa solids and cocoa butter can be extracted to form the basis of chocolate.
Today, it’s the West African countries of Côte d’Ivoire and Ghana that produce the bulk of the world’s supply of cocoa beans. But in recent years hotter temperatures and shifts in rainfall patterns have impacted cocoa harvests particularly in this region. And now the global price of this key ingredient has roughly doubled since the start of last year, fuelling concern that demand could outweigh supply.

Cocoa farming itself is mainly small scale and these farmers are at the bottom end of the value chain when it comes to profits. But whilst many of the major chocolate manufacturers do invest in the industry, with support for improved planting and harvesting techniques, farming sustainably is just one of a number of challenges that these small farmers face.
So on this week’s Inquiry, we’re asking ‘Is climate change impacting chocolate production?’

In February this year, El Salvador's president Nayib Bukele won re-election with nearly 85% of the vote. His flagship policy after he came to power in 2019 has been the mass arrest of thousands of alleged gang members, mainly young men.
It is estimated that over 100,000 people are now behind bars as part of his crime crackdown. The round-ups have been hugely popular with El Salvador's people as it has improved security and neighbouring countries are taking note.
But critics say following Bukele's approach could threaten democracy, not just in El Salvador but across the continent.

So on this week’s Inquiry, we’re asking: Will neighbouring countries follow El Salvador's lead on crime?

More than half of the world’s population currently lives in cities, and by 2050, the UN estimates that figure will rise to nearly 7 in 10 people. The world is also getting hotter, with heatwaves and wildfires becoming increasingly common.
So how can we deal with the dual challenges of increasing urbanisation and extreme weather caused by climate change? Perhaps we should look downwards.
For millennia, humans have taken refuge underground from the elements, predators and from war. Even today, bomb shelters exist under major cities like Beijing and Seoul. Many cities across the world have subway systems for easy transportation – and some are integrated seamlessly with below-ground business and shopping centres.
But what are the future challenges for urban planners and architects in this subterranean space, and how can we overcome the social stigma against those who live underground?
This week on the Inquiry, we ask: is our future underground?
