The use of medical marijuana is legal in 18 states and a group of state senators want Iowa to be number 19.
Lawmakers introduced a bill in the senate Wednesday to reclassify marijuana as a schedule two drug, which would allow doctors to prescribe it for pain relief related to illnesses like cancer and aids.
The bill would also create marijuana dispensaries for patients to get the drug.
Four Senate Democrats are sponsoring the bill including Senator Jack Hatch of Des Moines, Joe Bolkcom of Iowa City, William Dotzler of Waterloo, and Tom Courtney of Burlington.
Des Moines Representative Bruce Hunter has introduced a similar bill in the House.
The measures are expected to fail in both chambers.
