Green Man Festival is considering banning vape pens as part of their review of their 'not to bring list'.
It follows the decision by Glastonbury Festival, who asked festival-goers not to bring 'disposable vapes' to their music festival this month.
Green Man already has a list of banned items, which include pets and fireworks. Festival organisers are now deciding whether or not to add vapes to that list. Green Man state on its website that if people are found with prohibited items, they may be asked to leave.
Green Man will run from August 17 to 20 near Crickhowell, Powys, in the Black Mountains.
