Brewer Asbjorn Gerlach: many customers feel more awake

The brew - Turn - contains hemp although it does not contain any illegal substances.

But its label includes a picture of a marijuana leaf which the British drinks regulatory industry wants changed.

The beer is now being imported to Britain

The hemp is mixed with more traditional ingredients such as hops, malt and yeast.

The brewer claims drinking Turn may result in vivid dreams but getting high from the drink is a physical impossibility.

The beer only contains very small amounts of the chemical found in cannabis.

The drinker would have to consume more than 3,000 litres to feel the same affects as smoking cannabis.

After a successful launch in Germany, the beer has just been licensed to sell in Britain.

Thousands of litres of Turn will be exported every week for the British market.

It is not the content of the beer that worries the regulator but the drink's image.

The drinks industry wants the label changed

Importer Brian Haddow has been asked to change the label but he has resisted.

He said: "It is perfectly legal to bring it into the UK.

"I have a Home Office certificate to say there's no drug substance in the product.
