How does research for advocacy work in the case of tobacco and health? A useful new guide

I’ve been trawling through a ‘Research for Advocacy Action Guide’ from the Global Health Advocacy Incubator and Campaign for Tobacco-Free Kids, a US group (thanks to Ken Shadlen for the heads up). With its focus on health advocacy, especially in the US, it makes for an interesting comparison with my own experience at Oxfam, which works on a wider range of issues, more of them in the Global South. Both approaches have their strengths and weaknesses.
