Drug Addiction Treatment Act of 1999

Drug Addiction Treatment Act of 1999 - Amends the Controlled Substances Act to waive the requirement that practitioners who dispense narcotic drugs to individuals for maintenance or detoxification treatment annually obtain a separate registration for that purpose, and that the Attorney General register an applicant to dispense narcotic drugs to individuals for such treatment, in the case of the dispensing by a practitioner of narcotic drugs in schedule IV or V or combinations of such drugs (schedule IV-V drugs) if the practitioner and the drugs meet specified conditions. Limits the total number of patients of either a sole practitioner or of a group to 40 patients at any one time. Authorizes the Secretary of Health and Human Services to set different numerical ceilings according to the number of practitioners in the group practice. Requires that: (1) the practitioner, before dispensing schedule IV-V drugs to patients for maintenance or detoxification treatment, submit to the Secretary a notification of intent to begin dispensing such drugs for that purpose, including certifications that the practitioner is a "qualifying physician" (defined to mean a physician who is licensed under State law and meets specified training and experience requirements), and has the capacity to refer the patients for appropriate counseling and other appropriate ancillary; and (2) the schedule IV-V drugs have been approved for use in maintenance or detoxification treatment and have not been the subject of an "adverse determination" (i.e., requires additional standards regarding the qualifications of practitioners to provide such treatment, or requires standards regarding the quantities of the drugs that may be provided for unsupervised use). Sets forth specified procedural requirements to make the waiver effective. Directs the Secretary to assign a unique identifier to each notification of the intent of a practitioner to dispense schedule IV-V drugs to patients for maintenance or detoxification treatment, and to provide to the Attorney General all information contained in such notifications. Authorizes the Secretary and the Attorney General, during the three-year period beginning on the date of this Act's enactment, to make determinations regarding whether: (1) treatments provided under such waivers have been effective forms of maintenance and detoxification treatment in clinical settings; (2) such waivers have significantly increased the availability of such treatment; and (3) such waivers have adverse public health consequences. Authorizes the Secretary or the Attorney General, after consulting each other, to terminate the waiver mechanism after announcing their decision in the Federal Register. Authorizes appropriations to assist the Secretary with the additional duties established for the Secretary pursuant to this Act.
