Glastonbury discourages use of nitrous oxide after "two tonnes" of empty canisters removed in 2014

Liz Eliot, the co-ordinator of Glastonbury’s Green Fields, has released a statement pleading with festival goers not to use the gas in the area:

"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... the arrival of so much nitrous oxide in the King’s Meadow – some two tonnes of canisters were picked up, by hand, at Glastonbury 2014 – has darkened the field’s atmosphere. Now, though, is the time to reclaim the spirit and lighten up the energies. Nitrous oxide will not be welcome in the King’s Meadow at Glastonbury 2015, and we will be asking people not to use it."

Foo Fighters, Kanye West and one more artist (or two, if you believe the hearsay) are headlining the festival. For more information on the list of acts so far confirmed, head here.

Glastonbury 2015 takes place 24-28 June; it's sold out.
