Heavy Smokers Decrease, Light Smokers Increase More people today puff a few cigarettes per day than in 2005 By John Johnson, Newser Staff Posted Sep 6, 2011 5:19 PM CDT 8 comments Comments (Getty Images) (Newser) – 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." Other highlights: The number of heavy smokers (30 or more cigarettes per day) fell from 12.7% to 8.3% over the same period. The number of light smokers (one and nine cigarettes per day) increased from 16.4% to 21.8%. Daily smokers puffed an average of 15.1 cigarettes per day in 2010, down from 16.7 in 2005.
