The Cochrane Tobacco Addiction Group at the University of Oxford in the UK is one of the oldest groups working on Cochrane Reviews. It has produced dozens of these during the last two decades and, in 2016, it embarked on a project to identify the top priorities for future research into tobacco control. 

The Cochrane Tobacco Addiction Group's research prioritization exercise involved more than 300 people and identified a total of 183 unanswered questions in tobacco control through two online surveys and an Oxford-based workshop. It identified 24 priority questions, grouped into eight priority themes. This new set of research priorities to support tobacco control will help ensure future research provides the greatest benefit to public health and value for money.
