(2) The scientific evidence of its pharmacological effect, if known;
(3) The state of current scientific knowledge regarding the substance;
(4) The history and current pattern of abuse;
(5) The scope, duration, and significance of abuse;
(6) The risk to the public health;

(b) After considering the factors enumerated in subsection (a) of this section and after complying with subchapter I of Chapter 5 of Title 2, the Mayor shall make findings with respect to the factors and issue a rule either controlling the substance if the Mayor finds that the substance has a potential for abuse or deleting the substance if the Mayor finds that the substance does not have a potential for abuse.
(c) If the Mayor designates a substance as an immediate precursor, substances which are precursors of the controlled precursor shall not be subject to control solely because they are precursors of the controlled precursor.
(d) If any substance is designated, rescheduled, or deleted as a controlled substance under federal law, the Mayor may similarly designate, reschedule, or delete the controlled substance under this chapter, or may otherwise designate, reschedule or delete as a controlled substance pursuant to subsections (a) and (b) of this section.
(e) Authority to control under this section does not extend to tobacco or to distilled spirits, wine, or malt beverages, as those terms are defined or used in § 25-103.
