Nicotine addiction is the second leading cause of death worldwide. According to the Centers for Disease Control and Prevention (CDC), around 44 million adults got addicted to cigarette smoking in 2011, with majority being from the low-income class in the U.S. Similar conditions prevail in other countries and pose an equal threat to human lives. Cigarette smoking is a primary cause of lung cancer and other respiratory and cardiac diseases. Awareness about these health hazards has encouraged smokers to adopt smoking cessation therapy.
