184 countries signed up to fight Richard Nixon's War On Drugs. New Zealand adopted these drug policies and for decades has lead the world in arresting its citizens for cannabis. Now even as the US turns its back on the failed prohibition of marijuana, New Zealand refuses to change its approach. Someone is arrested here for cannabis every thirty minutes - despite the fact that no one has ever died from using it, the war on cannabis has no end in sight. Through cannabis users and growers, police officers, economists, doctors, politicians and scientists, we examine the cause and effect nature of the underground cannabis business - and explain how other jurisdictions have pulled this black market out of the darkness.
