The five-year Population Assessment of
tobacco and Health (PATH) Study of about 46,000 people, begun in 2011, is expected to provide a wealth of data about smoking behavior that could shape regulations ranging from warning labels and advertising restrictions to new product approvals.
"It is going to provide the most fine-grain, comprehensive, highest quality data on
tobacco use that has ever been collected in the United States," said Stanton Glantz, a
tobacco control expert at the University of California, San Francisco.
