Nitrous oxide, laughing gas, hippie crack – whatever you know it as – is not welcome at Glastonbury 2015.

Organisers of the summer gig claim the legal high, which has exploded in popularity in the recent years, has slowly been ruining the infamous festival and they state it’s not welcome at this year’s event.

Co-ordinator Liz Eliot made a plea on the event’s website to festival-goers to leave their cannisters of nitrous oxide at home to help reclaim their “sacred place”.

“I’m writing to ask for your help in reclaiming the King’s Meadow – our Festival’s Sacred Space – as a place where people can gather in peace, for fun and spiritual awakenings,” Liz wrote.

“Sadly the King’s Meadow has lost its way. It’s become known as a place where people take nitrous oxide, a damaging drug which pollutes our beautiful field with noise, litter and N2O gas (a greenhouse gas which is 298 times more polluting than carbon dioxide).

“Nitrous oxide is also dangerous: an exploding canister was the source of a major injury at last year’s Glastonbury.

“It breaks our hearts to see our Sacred Space used this way – and we know from many messages we’ve received over the last few years that lots of you feel the same way.

“Nitrous oxide will not be welcome in the King’s Meadow at Glastonbury 2015 and we will be asking people not to use it.

“Each year we come together to share the magic of this truly wonderful festival. Please show your love for the event and each other by showing your appreciation of the land and our spiritual connection to it.

“Help us – please do not bring nitrous oxide onto the site and support us by not using it in the King’s Meadow.”
