In America it’s an epidemic. Now new evidence raises concern about the UK’s use of prescription opioids. Michael Mosley goes on an immersive journey to ask what can be done about it. 　　The opioid epidemic has devastated America. But what’s the situation here? A new report from Public Health England raises serious concerns about Britain's own relationship with painkillers. Dr Michael Mosley embarks on an immersive journey to Britain’s opioid frontline and meets patients struggling with addiction and GPs fighting a constant battle to help those suffering from chronic pain. He also uncovers worrying evidence of people abusing over-the-counter opioids and discovers how easy it is to buy strong opioids online. 　　Nearly six million people in England and Wales were prescribed an opioid last year. Michael wants to uncover how and why we’re consuming twice the amount of opioids as twenty years ago, especially when the scientific evidence he encounters disturbingly suggests that for the majority of people taking them for chronic pain, these drugs mostly don’t even work. Though a vital tool in our doctors’ armoury to combat acute pain and in cancer and end-of-life care, the Public Health England report revealed that more than half a million people have been on opioids for more than three years. 　　Michael cautions that people taking these drugs should not suddenly stop taking them. Nevertheless, as he discovers, long term or high dose use does leave them exposed to greater risk of side effects including dependency, addiction and even accidental death by overdose. 　　As many as 28 million Britons endure chronic pain - and if we’re to kick what seems like a dangerous national opioid habit, Michael believes that the critical issue is deprescribing. Millions now require help coming off opioids and drug-free alternatives to them. For Michael this is nothing short of a challenge as important as the fight against cancer and heart disease. 　　So how much do people on the ground really know about these powerful painkillers, some of which, including fentanyl, can be many times stronger than heroin? On his travels, Michael meets Karen in Hastings who now believes her five years on increasingly strong opioids ‘turned her into a zombie’. But he also encounters Brenda in Salford who thinks the morphine she has taken for fifteen years to help with her excruciating back pain is the thing that makes her life just about bearable. And he spends time with Vicki whose 50+-a-day over-the-counter painkiller habit led to overdose and near death before she finally admitted her addiction and started detox.

本部纪录片是BBC地平线系列节目四十年来颇具争议的一次感官剥夺实验。此次实验由圣乔治医院精神创伤心理科的领头人伊恩·罗宾斯教授发起，他从世界各地邀请六位曾在英国关塔那摩被拘留和受过酷刑的人，研究他们大脑所经历的变异。这六位志愿者被置身于一个核燃料仓中，其中三人被安排独自待在黑暗的隔音房中，而其他三人则戴上护目镜和泡沫箍袖带，被安排在刺耳的白噪音中。等待他们的是足足48小时的漫长煎熬。 　　最初的实验是由顶级心理学家唐纳德·赫布教授于二十世纪六十年代进行的，但很多北美政治和科学团体认为该实验极其残忍，被迫中止。
