A bill to amend part S of title I of the Omnibus Crime Control and Safe Streets Act of 1968 to permit the use of certain amounts for assistance to jail-based substance treatment programs, and for other purposes.

Amends the Omnibus Crime Control and Safe Streets Act of 1968 to authorize: (1) a State to use residential substance abuse treatment grant amounts to provide non-residential substance abuse treatment aftercare services for State prisoners, subject to specified requirements and certification by the State's chief executive officer; and (2) not less than ten percent of the total amount made available to a State for residential substance abuse treatment for State prisoners to be used for grants to local correctional facilities in the State to assist jail-based substance abuse treatment programs. Limits the Federal share (with respect to the latter) to 75 percent of the total program cost.

Grants preference to applications that provide for certain aftercare services and periodic substance abuse testing. Requires States making grants to implement a statewide communications network with the capacity to track participants.
