One day last summer, residents of rural Norfolk began to complain about a strange and pungent smell wafting across the Fens just south of King’s Lynn.

Likened by some to burning leaves, and others to a noxious strain of freshly mown grass, it lingered for days, causing locals to complain of nausea and headaches and eventually sparking a formal investigation by the district council.

‘The issue is not limited to Fenland, with the odour being reported across Cambridgeshire and Norfolk,’ declared a council spokesman. ‘Along with Environmental Health teams from neighbouring authorities, we are continuing to search for the source of the smell.’

Soon, officers were knocking on the door of a massive greenhouse complex covering roughly 18 hectares of farmland (the size of 23 football pitches) next to the River Wissey, on the outskirts of Downham Market.

The facility, owned by British Sugar, had originally been built to cultivate tomatoes. But in recent years, the site had quietly undergone an intriguing transformation.

Today, it happens to be the location of Britain’s only legal cannabis farm.

Here, thanks to a special licence quietly granted by the Home Office, a huge crop of marijuana was being cultivated on behalf of a British drug company called GW Pharmaceuticals.


the affair highlighted an intriguing, but little-known fact: that this vast horticultural unit, down a secluded country lane and largely shielded from view by hedgerows, is almost singlehandedly responsible for Britain’s status as the world’s largest producer of medical cannabis.

According to a 2016 UN report, we currently grow around 95 tonnes of the stuff each year, accounting for 45 per cent of global production and roughly 70 per cent of exports. And virtually all of it comes from this one, unassuming greenhouse in rural Norfolk.
