Its owner Jimmy Ward wants the law changed to allow him to sell organic marijuana over the counter in a Dutch-style cafe.

He hopes the new venture in Dorset, which is operating as a members-only venue, will help the cause of campaigners calling for the legalisation of cannabis.

Dorset Police have warned they will not tolerate any illegal behaviour at the premises, such as the sale of drugs.

Mr Ward said he was pleased at the number of visitors present when he opened at 1000 BST on Monday.

Mr Ward said he was not worried by police concerns about the cafe.

He said: "Every time the police get involved all they do is make me more determined."

Some customers had come from Stockport, Greater Manchester, where a similar cafe opened six months ago, but there were also local people at the opening.
