An Iowa Senate Subcommittee approved a bill to expand the state's medical marijuana program for a wider range of health problems.

It would also let health care providers approve use of marijuana products for any condition for which they determine could be "medically beneficial."

Currently, patients who want to join the medical marijuana program have to get a doctor to certify a "qualifying medical condition" like Crohn's disease, AIDS, or seizures.

The bill is now headed to the Senate Judiciary committee.
