Makes property forfeitable to the United States upon the commission of the act giving rise to forfeiture. Permits the forfeiture of property which has been transferred to a third party, but includes a provision protecting innocent bona fide purchasers. Authorizes a court to order the forfeiture of substitute assets of the defendant where the original property cannot be located or traced. Authorizes a court to take appropriate action preserving the availability of property during the pre-indictment period effective for up to 90 days.

Directs the Attorney General to establish regulations governing the restitution and disposition of forfeited property. Amends the Comprehensive Drug Abuse Prevention and Control Act of 1970 to establish general criminal forfeiture provisions for felony violations under titles II and III. Includes provisions similar to the RICO amendments of this Act, relating to property subject to forfeiture, third party transfers, asset substitution, pre-indictment orders, and remission. Authorizes a court to issue a warrant authorizing the seizure of property subject to forfeiture in the same manner provided for a search warrant, if other injunctive relief would not assure the availability of the property. Provides that a criminal forfeiture proceeding shall stay any civil forfeiture proceeding with respect to the same property.
