That's really the key provision, and it only makes sense. If one legalizes the cultivation of oranges, it only makes sense that it implies that all parts of the orange are legal (juice, concentrates, peel, pulp, etc.,) How could an extract of an orange be illegal when the entire fruit is not? It isn't an exact comparison, so it was smart to make it explicitly clear that industrial hemp is explicitly defined to include “all derivatives, extracts, cannabinoids, isomers, acids, salts, and salts of isomers” of industrial hemp.
