Their constitution prescribes that the state will provide free access to public health services through a three-tiered health system which provides preventative, promotive, and curative services. Because of this policy, Bhutan was able to eliminate iodine deficiency disorder in 2003, leprosy in 1997, and achieved childhood immunization for all children in 1991. It became the first country to ban tobacco in 2004, and cases of malaria decreased from 12,591 cases in 1999 to 972 cases in 2009.[1] The elimination of these diseases and the strong push for GNH allows for all people (including adolescents who are provided with many necessary items and free education) to live happier lives than they otherwise may have had.
