Introduction and Aims: Gambling research is characterised by widespread gambling industry involvement. It is likely (as with alcohol and tobacco industry influence) that this will delay or divert effective harm prevention or minimisation measures. Gambling harms are known to be significant and widespread. Effective action to reduce these harms requires concomitant efforts to eliminate industry influence. Design and Methods: Gambling industry influence and activity in three research forums is described. The influence of tobacco and alcohol industry involvement in research directions and outcomes is discussed. Aspects of the discursive elements of industry funded and/or directed research outputs are analysed in the context of industry-friendly discourse and its effects. Industry activity and participation at representative research forums is outlined. Results: The examples and background provided demonstrate that specific material and discursive effects of gambling industry involvement can be discerned in the gambling literature. The consequences of this for the gambling evidence base around harm prevention and minimisation are presented. Discussion and Conclusions: Industry influence operates at multiple levels within the gambling research field. There is increasing awareness of this, and of the effects it may have on the development and deployment of effective harm prevention and minimisation efforts. Key reforms are proposed: (i) the elimination of industry participation and sponsorship of gambling research associations and forums; and (ii) the establishment where necessary of new research forums and international scholarly associations.
