I'm planning on taking 2C-B at gig this weekend. It says drugs dogs will be in operation. Is it true that dogs are normally only trained for one substance? Surely if so they'd only be looking for MDMA and coke. Are dogs even trained to smell 2C-B? It's pretty rare so I'm guessing it shouldn't be an issue, seems like it'd be a huge waste of resources to catch out just a couple of people. I know people who have been to this venue recently and they were police dogs, which I hear are better trained.
