The Portman Group said pictures on the labels of the drinks that resemble cannabis leaves violate alcohol marketing rules by associating the products with illegal drugs, The Daily Mail reported Tuesday.

The offending beverages are produced by Spanish firm Beveland SA and were brought into Britain by Ultimate Brands Ltd. An Ultimate Brands spokeswoman said the company has agreed to halt importation of the drinks.

"Too many young adults these days regard alcohol and illicit drugs as interchangeable," said David Poley, chief executive of the Portman Group. "The industry must not contribute to this attitude but instead distance itself totally from illegal drugs."

The drinks, which are believed to contain hemp, did not violate any drink contents rules.
