Supporters of medical marijuana in Kansas have joined two Democratic state lawmakers at a Statehouse rally in favor of a bill legalizing marijuana for medical use.

About 50 people attended the rally Thursday.

Rep. Gail Finney, of Wichita, and Sen. David Haley of Kansas City filed medical marijuana bills prior to the start of this year’s legislative session. Similar measures have been filed since 2009, but none of them have made it to the discussion stage in committee.

But the Senate Public Health and Welfare Committee plans informational hearings next week.

In addition to Thursday’s rally, several medical cannabis groups were lobbying state lawmakers on behalf of patients and caregivers throughout the day.

More than 20 states across the U.S. have legalized the use of medical marijuana.
