The percentage of people who smoke in the U.S. remains stable--one out of every five adults. Since 2005 the proportion who smoked 30 or more cigarettes per day decreased by more than 25% (12.6% to 9.1%). Approximately 443,000 U.S. adults die from smoking-related illnesses annually, and smoking costs the U.S. $193 billion each year in direct costs and lost productivity.
