Smoked, eaten, imbibed — or just talked about — it seems the world has a strong
appetite for cannabis. An estimated one in five European adults have tried it. Thirteen million Europeans have consumed it in the past month. Globally, nearly 50000 tonnes of cannabis herb or resin is produced for consumption each year. Little wonder, then,that cannabis has become a controversial cultural and commercial phenomenon.Today, cannabis has a unique ability to divide opinion among policymakers, scientists, law enforcers, drugs professionals and consumers.
