Tobacco production in Malawi is one of the nation's largest sources of income. As of 2005[update], Malawi was the twelfth-largest producer of tobacco leaves and the 7th largest global supporter of tobacco leaves.[1] As of 2010, Malawi was the world's leading producer of burley leaf tobacco.[2] With the decline of tobacco farms in the West, interest in Malawi's low-grade, high-nicotine tobacco has increased. Today, Malawian tobacco is found in blends of nearly every cigarette smoked in industrialized nations including the popular and ubiquitous Camel and Marlboro brands. It is the world's most tobacco dependent economy.[3] In 2013 Malawi produced about 133,000 tonnes of tobacco leaf, a reduction from a maximum of 208,000 tonnes in 2009 and although annual production was maintained at similar levels in 2014 and 2015, prices fell steadily from 2013 to 2017, in part because of weakening world demand but also because of declining quality.[4]
