BBC News OnlineThree people have been charged with drugs offences at Scotland's first cannabis café, police said.
A Lothian and Borders Police spokesman said: "Three people have been arrested and charged with possession of drugs under the Misuse of Drugs Act."
He added: "Two people were seen using drugs within the premises."
The Purple Haze Cafe, a former greasy spoon, was opened on Thursday afternoon as a private members' club.
Café owner Paul Stewart said that cannabis would not be on sale.
Mr Stewart said he wanted to highlight the discrepancy between the way that the reclassification of the drug was being implemented on different sides of the border.
"In the rest of the UK the presumption of arrest has been taken away, but that presumption still remains in Scotland," he said.
Scottish Socialist Party MSPs Tommy Sheridan and Rosemary Byrne signed up to become members of the cafe.
Mr Sheridan said: "The people in this cafe want to take drugs off our streets and I think most people in Scotland would want to take drugs off our streets."
Earlier, First Minister Jack McConnell had condemned the cafe.
He said: "Those who are attempting to interpret the law for their own ends, I think, should think about the consequences of their actions."
Mr McConnell said Scottish police forces would continue to report cases involving cannabis to procurators fiscals, who would then consider what action should be taken.
He also described the Socialists' position as "shameful" and attacked "those who intend to interpret the law for their own ends".
