President Belisario Betancur, who had opposed extradition, announces, "We will extradite Colombians." Carlos Lehder is the first to be put on the list.

May 1, 2003: The Illicit Drug Anti-Proliferation Act of 2003 (IDAPA) is signed into law, among other things amending a section of the Controlled Substances Act to target rave organizers. It shifts the statute's emphasis from punishing those who establish places where drugs are made and consumed, such as "crack houses," to those who knowingly maintain "drug-involved premises," including outdoor events such as rock concerts. In addition to the criminal penalties in the original statute, the amended statute adds a civil penalty, thereby lowering the standard of proof from beyond a reasonable doubt to a preponderance of evidence.
