Politician Info

A board member for NORML has been active with marijuana reform for over a decade in her district.  Both Senator Olsen and Rep. Ballweg seemed sympathetic back in 2009 while the Republicans were in the minority under a Dem controlled legislature. 2010 changed as Republicans took control and basically killed everything marijuana related, always. Since then, Rep. Ballweg has really failed on the issue.

During 2019, Assembly Republicans worked on the issue and prefiled a bill for the 2020 legislative session to create a medical marijuana program in Wisconsin (Assembly Bill 750 / Senate Bill 683) which Rep. Ballweg (R-Markesan) failed to co-sponsor. 

March 2020 Republicans circulated a decriminalization bill for co-sponsorship which she did not co-sponsor.

NOTE: Advisory Referendums on Marijuana in 2018 passed 78% in Marquette County and 80% in Sauk County and Rep. Ballweg Constituent Surveys in 2019 had 73-83% support for marijuana reform.

Position on Marijuana Legalization


Position on Marijuana Decriminalization


Position on Medical Marijuana



"I believe any valid medicinal benefits from this plant should be studied and used. We now have authorization of CBD oil for seizures and additional treatment options could be found.

However, we should not be promoting products for smoking, given the effects on individual and public health. THC contained in the product does impair individuals on the road and in the workplace.

Those promoting medical marijuana claim it is an effective substitute for prescription opioids, and prescriptions have been reduced because of legalization. But actually, because of the awareness of addiction all states have seen prescriptions of opioids go down, including 30 percent in Wisconsin."  10/9/18
