When you purchase a ticket to Parklife, you are essentially agreeing to the festival's terms and conditions.
And while it's very tempting to skip over these during the sign-up process, it includes some very important rules regarding what festival-goers are allowed to take with them to the festival. Breaking some of these rules can result in you either being kicked out of the festival early or even getting in trouble with local authorities.
Obvious things that can't be taken to the Heaton Park event are illicit drugs and alcohol, including so-called 'legal highs' such as Nitrous Oxide - often referred to as 'laughing gas'. However, other contraband items may be regular items you take with you everywhere.
