Cannabis in Wisconsin
CBD oil was legalized in 2014, but under tight controls and for a very limited number of conditions, primarily seizures.
Wisconsin was historically a major producer of industrial hemp until 1958, though a 2017 law has re-opened Wisconsin for hemp farming.
The Rens Hemp Company of Brandon, Wisconsin, closed in 1958, was the last legal hemp producer nationwide in operation following the World Wars. Prior to its 1957 shutdown, Rens had been the primary provider of hemp rope for the United States Navy.
The 1939 legislation “161.275 Possession and use of marijuana; penalty” stated that the penalty for “growing, cultivating, mixing, compounding, having control of, preparing, possessing, using, prescribing, selling, administering or dispensing marijuana or hemp” would be no less than one year and no more than two years in the state prison.
Medical use of cannabidiol
In April 2014, Wisconsin Act 267 (2013 Assembly Bill 726) was enacted. The legislation nominally legalized the use of cannabidiol (CBD) in the state for treatment of seizure disorders. It was passed by a voice vote in the Assembly and a unanimous 33–0 vote in the Senate. It was renamed “Lydia’s Law” by an act a month later in honor of a seven-year-old girl who suffered from a rare form of epilepsy; the girl’s parents had pushed by CBD legislation in the state. The bill was criticized as being largely symbolic, as in order to gain support for passage in the Senate, its sponsors added a clause specifying that CBD oil must have FDA approval to be prescribed; prior to that clause the bill had support in the Assembly but was stalled in the Senate. Because CBD does not yet have FDA approval, and because a complex series of steps are required to allow trial usage, Wisconsin doctors are not allowed to prescribe CBD. As of May 2015, CBD advocates stated that they could not find a doctor in Wisconsin willing to prescribe CBD. In mid-2015, a state legislator proposed an amendment to remove penalties for possession of CBD oil, negating prescription requirements, but the amendment still would not provide a legal way to create or obtain CBD oil.
In February 2017 the Wisconsin Senate passed Senate Bill 10, a bill allowing people to possess CBD oil by a vote of 31-1. Senate Bill 10 amends Lydia’s Law (2013 Act 267), which allowed access to CBD oil under limited circumstances in Wisconsin. Senate Bill 10 allows for possession of CBD oil in Wisconsin if a doctor has certified the oil is being used to treat a medical condition. In addition, the bill requires Wisconsin follow suit if CBD oil is rescheduled at the federal level.

2013-14 Legislative session had 6 bills related to marijuana reform
Menominee Indian Reservation
In August 2015 the Menominee Indian Reservation held a vote on proposed measures to legalize medical and/or recreational cannabis. The Menonimee are uniquely placed in the state, as the only American Indian reservation which falls only under federal law, rather than under Wisconsin Public Law 280 like all other reservations in the state, meaning that the state of Wisconsin cannot prevent legal changes within the sovereign reservation.
On April 1, 2014 voters of Dane county voted on a nonbinding referendum to legalize marijuana. It passed with 65% of the vote.
City of Fond du Lac
On January 26, 2011 by Ord. No. 3450, marijuana for medical purposes was decriminalized within Fond du Lac city limits with the language “No person within the corporate limits of the City shall possess marijuana or a synthetic cannabinoid unless the substance was obtained directly from or pursuant to a valid prescription or order of a practitioner while acting in the course of his professional practice.”
