Allows the Attorney General to assess fines for failure to adopt or enforce the required testing policies.
Requires the Attorney General to report to Congress regarding any league that fails to comply with such policies and the effectiveness of the regulations under this Act.
Amends the Controlled Substances Act to double the maximum penalties for violations regarding anabolic steroids that occur near or at a sports facility or that involve an athlete.
Directs the Comptroller General to study the illegal use of performance-enhancing substances and other controlled substances by college athletes.
Allows the Attorney General to include as a major professional league any additional professional sports league or National Collegiate Athletic Association entities if such additions would prevent the illegal use of performance-enhancing substances and other controlled substances by athletes.
