What the record says

Wisconsin has no named ban on THC-O acetate. Wis. Stat. 94.55(1) defines hemp to include all derivatives and cannabinoids with a delta-9 THC concentration of not more than 0.3 percent, and 961.01(14) excludes hemp from marijuana. Wis. Stat. 961.14(4)(t) separately schedules THC in any form, including chemically synthesized THC. THC-O acetate is made by acetylating THC, a fully synthetic step, so the Schedule I reach is strong but rests on reading an acetate ester as a form of chemically synthesized THC. No per-serving cap or age rule is enacted.

Controlling language, verbatim

(t) Tetrahydrocannabinols, commonly known as “THC”, in any form including tetrahydrocannabinols contained in marijuana, obtained from marijuana, or chemically synthesized, except that tetrahydrocannabinols do not include any of the following:
