        Enforcement Administration, research, development, testing, 
        evaluation, and cost-benefit analyses to improve the safety, 
        effectiveness, and efficiency of equipment and the effectiveness 
        and efficiency of reference libraries for use by Federal, State, 
        local, Tribal, and territorial law enforcement agencies for the 
        accurate detection of drugs, such as fentanyl and xylazine, 
        including--
                    ``(A) portable equipment that can detect and

                containing low concentrations of drugs and high 
                concentrations of cutting agents into their component 
                parts to enable signature extraction for field 
                identification and detection; and
                    ``(C) technologies that use machine learning or 
                artificial intelligence (as defined in section 5002 of 
                the National Artificial Intelligence Initiative Act of 
                2020 (15 U.S.C. 9401)) and other techniques to predict 
                whether the substances in a sample are controlled 
                substance analogues or other new psychoactive substances 
                not yet included in available reference libraries.''.
