The Maryland Senate has passed a measure to allow academic medical research centers to have medical marijuana programs.
The Senate voted 42-4 on Monday for the bill already approved by the House of Delegates, sending the legislation to Gov. Martin O'Malley.
O'Malley has not personally said whether he will sign the bill. However, the state health secretary, who is a member of O'Malley's cabinet, has expressed support for the measure.
The Senate vote came on the last day of the legislative session, which adjourns at midnight. Most major bills already have cleared the Legislature.
The Legislature will be working through the day and night to put the finishing touches on a variety of other bills. Measures to expand early voting, address liability for dog bites and facilitate public-private partnerships remain.
