Issue network versus producer network? ASH, the Tobacco Products Research Trust and UK smoking policy

Policy science studies of networks in smoking policy segment the smoking arena into a "producer network" of industrial and retail interests and an "issue network" of anti-smoking organisations. Case studies of ASH (Action on Smoking and Health) and the Tobacco Products Research Trust (TPRT) indicate that networks in smoking policy were more complex and overlapping. ASH pioneered a new style of media-conscious health activism in the 1970s with an anti-industry line. Nevertheless the strategy of harm reduction remained an objective for industry and government, and also for some public health interests through the work of the TPRT. First safer smoking and then nicotine were the focus of these activities.
