@cjk The study might be fine. The question is, of all the possible studies, why that one and in whose interests? Also, they know exactly how such a study would be represented by those in the media with similar interests.
Don’t forget that Big Tobacco starting funding *any* health-related research just so articles on new discoveries would take the place of articles on the harms of cigarettes. Corporations are well versed in such PR tactics and worse.
