A single cigarette sold on a street corner may not cost a lot; however, the overall costs of smoking are huge.First, consider the cost of human life. The World Health Organization says about 10 people die of a tobacco-linked disease every minute.That rate adds up to almost six million people dying from such diseases every year.The majority of these preventable deaths happen in low-income and middle-income countries.The World Bank says each of these countries has a gross national income of less than $12,746.For most people, stopping smoking is hard. Many began smoking as teenagers. They are used to it. Also, tobacco contains the powerful drug nicotine.Studies show people who want to stop smoking can do so with different treatments.Some get help from electronic cigarettes, medicine or nicotine patches that reduce one's desire for the drug.Dr. Nancy Rigotti works at Massachusetts General Hospital in the United States. She says she finds that medicine and counseling services together work best of all.
