God, you sound like a right laugh. Camp Bestival might not annoy so much. One of the very essential elements of Glastonbury for me and my mates is the freedom to do as many drugs as you like, wherever you like, whenever you like. Although I tend to sniff more ket than coke in the daytime, I don't see why anyone should have any qualms about people doing bumps of whatever at the stages, or indeed wherever they feel like it. There isn't meant to be many rules at a festival, if a person doing drugs near offends you then Glasotnbury is no longer for you.
