Montana Gov. Brian Schweitzer has vetoed a bill that would have repealed the state's voter-approved medical marijuana law.
Schweitzer, a Democrat, vetoed the Republican-backed measure Wednesday along with several others he called "frivolous, unconstitutional or in direct contradiction to the expressed will of the people of Montana."
Montana voters in 2004 overwhelmingly approved the use of medical marijuana by the very sick. There are now more than 28,000 registered medical pot users.
Supporters of repeal say the boom has gone too far and that the voter initiative has too many holes to be effectively reformed.
A separate bill proposing changes in the law is now in conference committee. It may be this Legislature's last chance of acting on the issue with little more than a week left in the session.
