Legal Highs Warning At Bestival
People are being warned not to take so-called legal highs to Bestival.
Hampshire Police says officers and sniffer dogs will be carrying out extra checks to make sure people aren't bringing drugs to the music festival on the Isle of Wight.
The so-called party drugs have been banned and as they may contain illegal drugs, people could still be arrested if caught with them.
Three people have died after taking them in Hampshire in the past year.
Superintendent Will Schofield said:
"The use of so-called 'legal highs' is not accepted at Bestival. We're reminding people of national warnings that these substances have the potential to be extremely harmful, posing similar health risks to illegal drugs.
"Recent research suggests that some legal highs sold on the internet actually contain illegal drugs.
"Do not experiment by taking a substance when you cannot be sure of its contents. The effects are unpredictable, dangerous, and possibly deadly.
Amnesty bins are also provided on each entrance gate for people to give up banned substances.
