The CDC is out with new stats on smoking, and the big headline is that the number of adults who partake has fallen from 20.9% in 2005 to 19.3% in 2010, report MedPage Today and the Wall Street Journal. That means about 3 million fewer people are smoking today, but "it's been much slower than the rate of decline in the previous five years," says a CDC official. "We can certainly do much better."
