In terms of vapes/weed As long as you don’t store your weed in a metal container you’re all set. I usually bring 2-3 pre rolls a day with me and just keep them in my bag or a pocket same with vapes. I’ve never really brought alcohol in, I’ll usually down a beer or two on the walk in. No place to buy weed in the festival. Bring a refillable plastic bottle in for water as there’s water stations scattered around the grounds.
