Electronic cigarettes (e-cigarettes) are battery-operated devices that deliver nicotine in a vapor form by heating a solution commonly comprised of propylene glycol, nicotine, and flavoring ingredients. Since entering the U.S. market in 2007, e-cigarettes have attracted a growing supply of consumers, with sales increasing from $20 million in 2008 to approximately $1.5 billion in 2014. 1 The U.S. Centers for Disease Control and Prevention found that 12.6 percent of U.S. adults reported ever trying an e-cigarette in 2014. 2 Ecigarette sales are projected to further increase in the years ahead.
