Going to a music festival has become a rite of passage for the post GCSE teenager. Their excitement at the prospect of a long weekend of unsupervised possibility is perhaps only matched by the anxiety of their parents who know exactly what that might entail. Those fears may have been heightened by the news that a music festival in Cambridgeshire has just become the first UK event of its kind to offer people the chance to have their illegal drugs tested to establish the purity of content before they take them. The testing facility, at the Secret Garden Party, was offered with the co-operation of the police. The organisers said the aim was to reduce harm from drug taking and promote welfare. The group conducting the forensic tests this weekend hope other festivals will follow suit. Is this a pragmatic and realistic approach to drug taking that will save lives or a tacit endorsement that will cost them? Is it part of a gradual slide toward decriminalisation of drug taking? According to the 2016 European Drug Report, ecstasy has surged in popularity in Britain among those aged 15-34 in the past three years. Is it logical on the one hand to criminalise the sale of legal highs, but on the other to make it easier to take an illegal drug like ecstasy? Needle exchanges have long been available to registered intravenous drug addicts. Is this a logical extension or does discovering people have illegal drugs and then allowing them to walk away and use them, while the police turn a blind eye, cross a moral Rubicon? It will make it safer for people who want to take drugs, but what about those people who want to attend a festival knowing it is drug free? How should we balance those competing moral goods? Witnesses are Dr Ian Oliver, Johann Hari, Steve Rolles and Deirdre Boyd.

MP's have voted overwhelmingly to renew our Trident nuclear weapons system and the first job of any new prime minister is to write the "letters of last resort" which contain prime ministers' instructions for what to do in the event of a nuclear attack. The handwritten notes are taken to the UK's four Vanguard-class submarines, the ships which carry the ballistic missiles the Royal Navy calls "the nation's ultimate weapon" and contain instructions of what to do in the worst-case nuclear scenario: the obliteration of the UK state. The value of nuclear weapons is in their deterrence - the promise of mutually assured destruction. Theresa May has told the Commons that she wouldn't hesitate, but she could do no other. It is rumoured previous prime ministers may not have been so certain. By their nature the letters have to make broad moral judgments rather than situationally-dependent ones. They're about morality and ethics, not tactics. In the event that deterrence fails and we are attacked, would it be moral to use our nuclear weapons against civilians in retaliation? What would you do in the event of nuclear war? Under the 1949 Geneva Conventions, collective punishment is a war crime. If you think the moral principles of collective punishment are clear when it comes to nuclear weapons what about in other stories in the news? Is it always wrong to punish the innocent in pursuit of a wider justice? Should we ban all Russian athletes from the Rio Olympics to punish the drug cheats? Is protecting American citizens against terrorist attacks a greater good than the right of Muslims to travel to the USA? The morality of retaliation and collective punishment on the Moral Maze. Witnesses are Major General Patrick Cordingley, Air Vice Marshall Nigel Baldwin, Avia Pasternak and Austen Ivereigh.

130 sessions of oral evidence,150 witnesses, 150,000 documents, more than 2.5 million words - the Chilcot Report on the Iraq War was finally published on the day of this programme. The inquiry was set up to examine our reasons for taking part in the US-led invasion of Iraq, how the war was prosecuted and its aftermath. But was the decision to go to war morally justified? Chilcot confirms that there was a massive failing in intelligence in the lead-up to the decision to go to war, especially around WMD; it accepts that Tony Blair was acting in good faith and did not deliberately mislead Parliament and the public about that intelligence. The relationship between morality and consequences is complex and sometimes contradictory. If Tony Blair and his government were acting in good faith but the consequences of that war were so catastrophic, can we still describe the decision to go to war as a moral one? If the government were a limited company, isn't this the kind of gross negligence that would lead to directors being prosecuted for corporate manslaughter? On the other hand, if - being wise after the event - we were to hound all politicians for making decisions that went wrong, wouldn't that produce sclerosis and the replacement of democratic judgement with technocracy? Is this a counsel of moral perfection that produces only paralysis of the will? When does ignorance become a moral failing? Is that contingent on outcomes? What if the war had been a success and Iraq transformed into a flourishing democracy? Would we still be worrying about whether it was moral? Would we have spent £10m on an inquiry about it?

Pundits and politicians alike are struggling to capture the enormity of the consequences of the result of the referendum vote. It's at times like these people often turn to George Orwell for inspiration. He likened our nation to "a family with the wrong members in control" - "that" he said "perhaps, is as near as one can come to describing England in a phrase." Who'll be left standing and in charge after all the political recriminations and bloodletting have ended is still not clear. It's been described as the worst peace-time constitutional crisis this country has faced. So this week on the Moral Maze we're asking what should now be the moral priority for the victors and the vanquished? Has the democratic will of the people been clearly expressed so that the victors must now deliver Brexit at any price? Is it the moral duty of those who championed Brexit to deliver on all their promises made during the campaigning? Or, once normal politics has resumed, should the utilitarian principle of cutting the best possible deal triumph - even if that means forgetting campaign promises on immigration and the single market? Should the vanquished now support Brexit and work towards it with all the enthusiasm they can manage? Or was this a mistake by the British people that means they have a moral duty to go on fighting to keep Britain in the EU and campaign for a second referendum? Or should the priority, above all others, be to find a way to heal a divided nation?

The murder of the MP Jo Cox has cast a very long and dark shadow across the closing days of the EU referendum. The nature of the campaign and how her death might influence the result are a matter of conjecture. On this week's Moral Maze we're going stand back from that speculation and ask a much bigger question - has this referendum been good for us and good for democracy? The intense campaigning has been going on for many months now and comes hard on the heels of the Scottish independence referendum. Arguably, both have been characterised by trenchant, sometimes bitter and even abusive debate between two sides passionately and honestly committed to their positions. And, arguably, both referenda have left large parts of the electorate dissatisfied by a seemingly endless round of fact-free claim and counter-claim. Are our expectations unrealistic? Have referendums been, for all their faults, exercises in democracy that have engaged and inspired people in a way that party politics increasingly fail to achieve? Should we, like Switzerland, hold more of them? Is there a better way? Should we turn to technology and the internet for answers? 76% of people in the UK own a smart phone; with the growth of social media and online petitions there's a movement that believes the future of democracy is online, where it will engage more people in a wider variety of issues, putting more power directly into the hands of the electorate. Will e-democracy encourage more passionate engagement in issues and be a powerful force for progress? Can it cope with complex issues and complex societies with tens, or hundreds of millions of voters? Will we always need representative democracy to protect us from the tyranny of the majority, however that majority cast their votes?

Every year thousands of terminally ill patients are being helped to die by their doctors, according to Baroness Molly Meacher, the new chairwoman of Dignity in Dying. She claims doctors are prepared to risk their own freedom rather than see their patients continue to suffer unbearably. Her assertion comes as the British Medical Association next week prepares to discuss the results of its 18 month long survey in to the public and medical professionals' attitudes on end-of-life care and physician-assisted dying. For 26 years now this programme has charted the moral and ethical life of the nation and this subject, above all others, has been the one we've returned to most often. And little wonder as it's an issue that combines moral dilemma, religious principle, human compassion and fear in equal measure. As a prelude to the BMA debate, this week we're going to invite back witnesses who've appeared on our programme over the years to explore how the debate has developed over time. In 1991 we started out discussing the morality of suicide manuals. Advances in medical technology since then have transformed our expectations of what we demand from life. We've seen a growth of the "me generation" that prizes and demands individual choice and rights above collective responsibility. While as a society we have increasingly recognised the rights of disabled people, there is also growing support for legalising assisted suicide, which may give comfort to some, but could put many more vulnerable people at risk. And there has also been our changing relationship with religion. The moral maze that is the debate on assisted dying, live at 8pm Wednesday. Chaired by Michael Buerk with Mona Siddiqui, Anne McElvoy, Giles Fraser and Claire Fox. Witnesses are Dr Michael Irwin, Lesley Close, Dr Kevin Yuill and Prof David Cook.

The sales signs are going up in 163 BHS shops around the country as the liquidators try to salvage something from the wreckage of this once proud company. When Sir Philip Green bought BHS in 2000, it was making a profit. By the time he sold it in 2015, for £1, to a three-times bankrupt with no retailing experience, it was making a loss and the company pension fund was more than £400m in deficit. Exactly what went wrong at BHS is the subject of no fewer than four separate inquires. What is certain is that it's you and I, the tax payers, who will pick up the bill for the redundancy payments for the 11,000 staff and responsibility for the 20,000 members of the BHS company pension scheme. The head of the Institute of Directors described the affair as deeply damaging to the British business world. It's all a far cry from the days of Quaker philanthropy that inspired so many Victorian entrepreneurs. The study of business ethics is one of the few growth areas of the economy. You might be forgiven for wondering how effective such courses are when we see so many headlines about companies avoiding tax, walking away from pension liabilities, using legal loopholes to make excessive profits, zero hours contracts, falsifying data, mis-selling... The list goes on. Do companies have any moral duty beyond the bottom line? Is the only duty of a company to make money for its shareholders within the law? Where and how do we draw the line between legal duty to shareholders and moral duty to society? The individuals that run companies have moral agency, but is there such a thing as a collective, corporate moral agency? Can we impose a set of moral values, or a social licence, on a company? Or will that create a climate of "What can we get away with?" rather than "What is right?"?

Would you ******* believe it? A council has ******* banned swearing in public. The council in question is Salford which has used a Public Space Protection Order to tackle anti-social behaviour in the Salford Quays area which includes Media City, home to the BBC, which might be just a coincidence. Part of the order says it will be deemed a criminal offence if anyone is caught 'using foul and abusive language'. Public Space Protection Orders, or PSPOs, are similar to ASBO's (anti-social behaviour orders), and allow for broad powers to criminalise behaviour that is not normally criminal. PSPOs are geographically defined, making predefined activities within a mapped area prosecutable. Since they came into existence in 2014 many councils have embraced their new powers enthusiastically, with various PSPO's making, or attempting to make, it a criminal offence to sleep rough, drive a loud car and walk a dog without a lead. It seems that control, or regulation, of public space is becoming more common. In the last month alone a council in Wales has banned smoking on a public beach, the London Underground is considering stopping people walking up escalators and a well known store asked a customer to leave because her toddler was having a tantrum. Are regulations to tackle public nuisance a commendable attempt to protect us or an oppressive enforcement of social conformity targeting public activities that are merely unusual or unpopular? This tension between individualism and the common good is an issue which bedevils so many aspects of contemporary society. If it is true that inconsiderate behaviour is increasing in our society, how should we deal with it? How do we balance our moral obligation to the rest of society with our desire to do what we **** well please?

The fact that the Belgian authorities had been expecting an attack doesn't diminish the shock of yet another bombing with mass casualties in a European capital. Belgium's foreign minister said on Sunday that Salah Abdeslam, the prime surviving suspect in the Paris attacks, could have been plotting more operations. Tragically, he was proved right. That Salah was able to hide in Brussels, under the noses of the Belgian police, for more than four months raises uncomfortable questions for them - and also for us. The UK government is still fighting to get its Investigatory Powers Bill onto the statute book. Its supporters believe it will enable the police and security services to fight terrorism and crime more effectively. Opponents say it will destroy our fundamental right to privacy and believe their arguments have been given more force by the revelations of Edward Snowdon about the extent of secret surveillance. The Brussels bombs came on the day that the FBI in America said they'd found a way to get round Apple's security and unlock the phone of an Islamist terrorist who killed 14 people in California last December. Apple had refused to co-operate, saying it would have security implications for millions of iPhone users all over the world. When we're faced with ruthless terrorists, intent on committing mass murder, how much privacy do we have a right to demand? And who should police it? These bombs were in the city that is the symbolic heart of the European Union and that has - for many - come to symbolise the hard-won freedoms and values we cherish in the West. What price do we place on those freedoms and values? And how much are we willing to compromise them to ensure our safety? How free do you want to be? Witnesses are Professor Anthony Glees, Mike Harris, Douglas Murray and Inayat Bunglawala.

Claim and counter claim in the EU referendum debate have filled the air waves and packed the papers and there are still 14 weeks left to the actual vote. The atmosphere is already highly charged and the political stakes couldn't be much higher. The way we vote on June 23rd will have profound implications for generations to come. We've heard a lot about the political and economic arguments that we should consider when casting that vote, but what are the moral considerations? Is preserving our national cultural identity behind strict border controls a moral priority? Do we have a wider duty as good citizens of Europe and the world? Is fear of immigration and fear of an uncertain economic future a defendable moral position? Is it a moral argument to say our choice should be a utilitarian calculation of where we personally and as a nation will be financially better off? Is sovereignty the moral trump card? Morality and the EU referendum. Chaired by Michael Buerk with Melanie Phillips, Michael Portillo, Matthew Taylor and Anne McElvoy. Witnesses are Anthony O'Hear, Kirsty Hughes, Brian Denny and Sebastian Farquhar.
