Halton Borough Council and Cheshire Police are warning Creamfields attendees that all drugs, including "legal highs", will not be tolerated at this year's event.
This year's event is due to begin on Friday 28th August for what will be the tenth time that the music festival has taken place in Cheshire.
People attending the event will be subject to stringent security checks as they enter the event, which will include both body searches and sniffer dogs, and anyone who refuses to be searched will be denied entry into the event.
Inspector Stewart Sheer from Cheshire Police said:
"Festival goers are reminded that security will be tight at the event. Security measures will be in place and it is important that those attending are aware of these.
"Drug use will not be tolerated and positive action will be taken by police. Searches are a condition of entry and drugs dogs will be used at the entrances to the site.
"Surrender Bins will be provided at the entrances for festival goers to place any drugs or weapons into. Anyone found with drugs or weapons, having not placed them into the bins, will be dealt with by police.”
"I would advise anyone considering bringing any such items to not bring them in the first place."
Halton Borough Council's Executive Board Member for Community Safety, Councillor Dave Cargill, said:
"We are all aware of the harm drugs can cause, so we have adopted a zero tolerance approach, in partnership with Cheshire Police."
Cheshire Police Drugs Expert Detective Constable Jamie Thompson said:
"In addition to illegal drugs, there will also be a zero tolerance approach to legal highs, such as nitrous oxide. Anyone who is found in possession of legal highs will be refused entry into the event.
"The advice is clear - if you are found in possession of any drugs, including legal highs, you will not be allowed into the event, and you may be prosecuted.”
