A decline has been witnessed in the adult smoking rate in America. A report released Thursday by the Centers for Disease Control and Prevention has unveiled that around 17% of American adults have smoked cigarettes in 2014, a drop of around 20% from adult smoking rate in 2005.

Those who continue to smoke, the number of cigarettes smoked daily has declined to 13.8% from 16.7% in 2005. Along with this, the CDC report has unveiled that there are many categories, where it has become quite difficult to bring a cut on smoking habit and especially among the poor.

Only 12.9% of adults having private health insurance continue to smoke cigarettes, but 29.1% of those on Medicaid were smoking in 2014. The smoking rate among adults who live below the federal poverty level of $19,790 in annual income of family having three members was 26.3%.

It has also been found that smoking rate is especially quite high among those having a general education development certificate (GED) at 43%, and also among those as multiracial (27.9%). The ones identified as lesbian, gay or bisexual were also having a high rate of smoking, 23.9% in 2014.

"The reduction in smoking prevalence over the last decade is a major victory for public health", affirmed Dr. Jaimee L. Heffner, a Fred Hutchinson Cancer Research Center expert in tobacco cessation.
