LINCOLN, Neb. (AP) — Less than a week after pushing a broad medical marijuana bill through a first-round vote, Nebraska lawmakers have advanced a second measure to provide faster, federally approved relief.

Senators voted 33-1 Monday to allow a study examining the effectiveness of a cannabis extract in treating epilepsy.

Nebraska would procure the low-potency drug from GW Pharmaceuticals. The United States has authorized the England-based company to provide the drug for rare diseases.

Sen. Sue Crawford of Bellevue says neurologists would monitor the study to determine the number of participants.

Sen. Tommy Garrett of Bellevue, who sponsored a bill to allow medical marijuana, says he supports Crawford’s bill because it would provide immediate access to the drug while the state sets up a medical marijuana program.
