(Value of Illegal Drug Exports from the Caribbean) "The value of illegal drug exports from the Caribbean during the past two decades has fallen into two very well differentiated periods. The first period, from 1981 to 1990, was an epoch of impressive depression in the total value of the Caribbean drugs exports -- from an income over US$20bn at its peak in 1983 to US$5bn in 1991. Since 1991, the value of Caribbean exports of illegal drugs has stabilised around US$5bn."
