The biggest threat to this new establishment: law enforcement. The second biggest threat: customers with the munchies, demanding extra haggis. The Scotsman reports: Scotland's first cannabis cafe is set to open next month when the drug is downgraded from class B to class C. The Purple Haze internet cafe in Leith will become a private club where people can bring small amounts of the narcotic to smoke. It will be the first such establishment to open in Scotland and will test how the new laws are to be applied by police. Cafe owner Paul Stewart believes turning the former greasy spoon into a private club in the evenings would allow him to operate within the law. Thirty-seven-year-old Mr Stewart said: "I use cannabis and I’m going to allow people to smoke it. I’m not going to sell it, but I’ll allow people to bring their own. I don’t think there’s going to be a problem, but I could be wrong. I could end up in jail."
