In an announcement, health officials have said that record number of smokers in the US have quit smoking in the past decade. The Centers for Disease Control (CDC) and Prevention shared happy news that the percentage of the US adults who smoke cigarettes has dropped from 20.9% in 2005 to 16.8% in 2014.

Figures have also revealed that cigarette smoking was significantly lower in 2014 being 16.8% as compared to 17.8% in 2013.

The main reason behind the notable fall in the number of smokers has not been mentioned. But some of the causes include improved insurance coverage for helping smokers who have leave the habit. Other main factor is the implementation of stricter laws, banning more smokers to smoke in more places.

In a statement, CDC director Dr. Tom Frieden said that every year half a million Americans die because of smoking and it costs over $300 billion. The report has shown real progress has been done in helping American smokers quit and that the progress could be boost.

Experts have failed to understand why anti-smoking campaigns receive most of the credit for the decreased number of smokers, when there are some other reasons too like improved insurance coverage for assisting the ones who quit, and also stricter laws that ban people from smoking in public places.

In September, Healthday reported that the fall was roughly 17% in 2014 and nearly 18% in 2013. On Tuesday, the US Centers for Disease Control and Prevention reported that the nosedive has reflected a continued fall, starting in 2010 after 10 years of no progress against smoking.
