The country with the biggest weed habit? That might surprise you.

A new report claims the UK government should legalise marijuana because it's “the only solution to crime and addiction problems”.

The strongly-worded study - titled The Tide Effect: How the World is Changing its Mind on Cannabis - was produced by the nonpartisan Adam Smith Institute and has the backing of several cross-party MPs including former deputy prime minister, Nick Clegg.

When you think of anti-cannabis crusaders, names like former President Richard Nixon and former First Lady Nancy Reagan immediately come to mind. But Napoleon Bonaparte - the French emperor and general who was tastefully portrayed by Verne Troyer on TV's Jack of All Trades - is also among the ranks of history's prohibitionists.

The world has had a long and complicated relationship with hemp.

It wasn’t until the twentieth century that hemp fell out of favor as one of the most important crops in the history of mankind. In 2016, however, anything is possible it seems.

Marijuana legalization has been a political issue in the United States for some time, and while it remains illegal in most states, others have softened their stance in recent years.
