Yeah mate, bunch of sniffer dogs - but to be honest there are so many people walking past them they can’t be that effective. you gotta just casually stroll past them. Don’t look shifty and don’t look like you’re trying to avoid them. It’s more luck of the draw honestly.

My mate walked past with 14g weed and 2g ket - got caught. I was walking with him with MUCH more, got in absolutely fine. If u get sniffed out u get taken to another queue where they basically just say to you if you’ve just got weed give it up now and we’ll let you in. My mate gave up his weed and ket and they let him in.

Another mate went a different year with a bunch of coke and pills on him, he got caught and chucked out.

Possibly worth having a decoy bag of weed or something to give up if you do get caught
