Is Medical Marijuana Legal in Green Bay, WI?
Facts on this page were checked against official sources, including Wis. Stat. 961.32 and the Wisconsin Legislature’s record for 2025 SB 534, by the Dr. Green Relief editorial team. Last reviewed October 19, 2026.
Medical marijuana is not legal in Green Bay: Wisconsin issues no medical marijuana card, though a physician licensed in Wisconsin may certify a CBD product for a medical condition. A card from Michigan or any other state does not help: Wisconsin honors no out-of-state card.
Our Wisconsin medical marijuana card page explains why no state card exists and what the CBD certification covers. Want to learn more about medical marijuana laws in Green Bay? Wisconsin has no medical marijuana program. You can sign up below for Dr. Green Relief updates on Wisconsin marijuana law. In Green Bay, Wisconsin law lets Brown County punish possession with a forfeiture by ordinance in every city in the county, but that ordinance cannot be used once a state complaint alleges more than 25 grams or follows a prior Wisconsin possession conviction, unless two things happen: the state charge is dismissed or not prosecuted, and the city, village or town where it happened has no marijuana possession ordinance of its own or has dismissed or not prosecuted its own ordinance case.
The state can still charge the same act as a crime under Wis. Stat. 961.41. No card is available to get. Wisconsin has no marijuana program registry to sign up for. The 2025 medical bill, SB 534, would have required an in-person visit with a prescriber and Wisconsin residency, but it failed in March 2026. Hemp-derived CBD sold in Green Bay stores needs no physician letter. Other non-psychoactive CBD products need a Wisconsin physician’s certification unless they are FDA-approved drugs.
