POLICE took a drug dog out in Sowerby Bridge to check for banned substances.
Five randomly-chosen pubs and clubs were visited by the team.
They carried out eight stop and searches and gave a formal warning to one man for possessing a small amount of a Class B drug.
Sergeant Jonathan Firth, from Halifax Central neighbourhood policing team, said they would be repeating the checks in the future.
Anyone with information about drugs in their area should call their neighbourhood policing team via 101.
Information can also be passed to Crimestoppers on 0800 555111.
