Former President Leonel Fernandez, at a conference at the Universidad Nacional Pedro Henriquez Ureña, said that the main threats the DR must face in the 21st century are drug trafficking, migration of Haitians, dependency on the US, AIDS and environmental deterioration. He pointed out that while the DR is being used as a bridge for the transport of illicit drugs to the US, the menace of what he called the "toll" payment of drugs left in the DR in the process is dangerously increasing the number of local consumers and creating a large market here.
