The number of cannabis clubs that have opened in Barcelona recently has some experts saying this city will soon challenge Amsterdam as the go-to destination for vacationers who want to get high in peace. In the last three years, new clubs have opened, particularly in tourist areas, in many cases circumventing the spirit, if not the letter, of the law. About 300 new cannabis clubs have opened in Barcelona and the surrounding Catalan region, a result, at least in part, of enterprising Spaniards looking for new ways to earn a living.
