A drugs dog will be visiting pubs across Hyndburn over the Christmas period to make sure revellers are not using anything illegal.
William the black Labrador and his handler Phil Evans have already been out and about in the Accrington and Oswaldtwistle areas.
On Saturday, December 11, they visited 15 different premises.
A small amount of discarded methadrone was recovered, but nobody was found to be in possession of any drugs and no arrests were made.
Sergeant Graham Brownsmith, from Accrington Police, said: "It’s good news that we’re not finding many drugs.
"Although drugs are not a massive problem in the area, they are something which will always be a concern for both the police and the public.
"I think it’s reassuring for people to see the police out and about with the dog.
"We’ve had a very positive response so far.
"The scheme has been very well-received by the licensees as well. They are glad to see the police actively tackling the issue of drugs."
Emma Kenyon, from Hyndburn's Community Safety Partnership, said she was delighted to be involved with the scheme.
She said: "We are always looking to tackle issues that are key to the community and we are pleased to be working with licensees to stamp out the misuse of drugs."
Five-year-old William and his handler Phil plan to continue their weekend visits thid week. Sergeant Brownsmith added: "It’s a privilege to be working with a dog like William – he’s a very valuable resource and we're lucky to have him."
