Study shows role of depression in the ongoing tobacco epidemic

The prevalence of smoking has remained fairly stable over the past decade after declining sharply for many years. To determine whether there was an increase in certain barriers to successful cessation, researchers analyzed changes in the prevalence of depression among current, former and never smokers in the US. They found that depression appeared to have significantly increased in the US from 2005 to 2013 among smokers and was most prominent among former and never smokers.
