Next date to watch

Federal 0.4mg cap 11/12 is the only operative clock for WI (no state ban). Gov Evers lobbying Congress to delay (~3,500 jobs/$700M).

Federal change scheduled for November 12, 2026

State rules are only one layer. Unless Congress changes the enacted provision, Section 781 changes the federal hemp definition to total THC—Delta-9 THC plus 0.877 times THCA—and adds a 0.4 milligram total-THC-per-container cap beginning November 12, 2026. That federal change is separate from the Wisconsin posture above.
