E-Cigarettes - a podcast by BBC Radio 4

More than two million people in Britain are thought to have used electronic cigarettes. Whitehall civil servants think that e-cigarettes are one of the most significant public health success stories of our generation. In Wales however, the principality's government wants to ban their use in public places. Wesley Stephenson asks why the two governments have such different approaches.

Producer: Smita Patel.
