The documentary explores the controversial use of marijuana and the evolution of mainstream society. From a dangerous narcotic, listed as a Schedule 1 Drug substance since the 1970s, to the rush to decriminalize it today. What has changed and why? What will the cannabis industry look like in five years? Will it retain its integrity as a homegrown industry or be co-opted by Big Business? Experts, growers, celebrities and politicians weigh in on the future of Cannabusiness.

The Magic Pill follows doctors, patients, scientists, chefs, farmers and journalists from around the globe who are combating illness through a paradigm shift in eating. According to its followers, this simple change - embracing fat as our main fuel - is showing profound promise in improving the health of people, animals and the planet. The film is highly controversial and was criticized by some medical associations.
The Paleo diet proposes that humans were genetically adapted to eating specifically those foods that were readily available to them in their local environments. Advocates of the diet claim many chronic diseases and degenerative conditions evident in modern Western populations have arisen because of a mismatch between Stone Age genes and modern lifestyles. The Paleo diet typically includes vegetables, fruits, nuts, roots, and meat and excludes foods such as dairy products, grains, sugar, legumes, processed vegetable oils, salt, alcohol or coffee.

A ground-breaking new trial at Imperial College London sees, for the first time ever under controlled conditions, a psychedelic drug tested head-to-head against a standard antidepressant as a treatment for depression. The film follows a pioneering team of scientists and psychotherapists as they compare the effects of psilocybin (the active ingredient of magic mushrooms) with an antidepressant on a small group of participants with clinical depression.
This is scientific research at its most cutting edge. With over seven million people being prescribed antidepressants each year in England alone, this drug trial is an important milestone in understanding a completely different treatment for depression. How do psychedelic drugs measure up against the industry-standard antidepressants that have been popular since the 1990s? The empirical results of the trial are explored alongside the participants’ powerful lived experience.

Gaby Roslin and Amir Khan present a program in which they apply the latest science to some of the worst sleepers. They include an extreme snorer, a man who suffers from night terrors, a woman who has restless leg syndrome, and a man with chronic insomnia for 20 years.
The film also shows a sleep deprivation experiment to test for risky behaviour, pain resistance and emotional control. When the subjects reach the final hours of the challenge, the experiment begins to take its toll as the participants' emotions go into overdrive, with one threatening to quit altogether.

Dr George McGavin and Dr Zoe Laughlin set up base camp at one of the UK's biggest sewage works to investigate the revolutionary science finding vital renewable resources and undiscovered life in human waste.
Teaming up with world-class scientists, they search for biological entities in sewage with potentially lifesaving medical properties, find out how pee can generate electricity, how gas from poo can fuel a car and how nutrients in waste can help solve the soil crisis. They follow each stage of the sewage treatment process, revealing what the stuff we flush can tell us about how we live today, and the mind boggling biotechnology being harnessed to clean it, making the wastewater safe enough to return to the environment.

Western countries are the most sleep-deprived countries in the world. Insomniac Michael Mosley finds out what happens if we don't get enough sleep and looks at surprising solutions to help us get more.
