A cigarette designer from the nation's number two tobacco company today denied his company modified cigarettes to hook smokers. Tobacco companies are using David Townsend's testimony to counter claims by the state and Blue Cross Blue Shield that they manipulated nicotine content in cigarettes, and conspired not to develop safer products. Minnesota Public Radio's Laura McCallum reports... By the way, the tobacco companies have until tomorrow to persuade the U-S Supreme Court to hear its case regarding secret industry documents. If the high court refuses to hear the case, the companies must turn over the documents to the state. We will have that story tomorrow night on ALL THINGS CONSIDERED.
