Cannabis is the UK's favorite illegal drug. An estimated half million people use it for medicinal purposes, and many more use it just to get high. In the past decade, several countries have moved to decriminalize or even fully legalize smoking and growing weed, yet the UK government refuses to budge. When more than 200,000 people signed a petition last year calling on the city of Westminster to make the production, sale, and use of weed legal, the government responded with a flat-out "no." Yet in some ways, decriminalization is happening through the back door, with many British police forces no longer making cannabis crackdowns a top priority.In this episode of High Society, we explore how that approach to the issue shapes the country's weed culture and meet growers, medical marijuana users, politicians, and a couple of thieves who have come up with a novel way to make money off the UK cannabis trade.
