Maryland Gov. Martin O'Malley (D) said Monday that he will sign a bill decriminalizing possession of small amounts of marijuana, reports the Washington Post.

On a 34-to-8 vote, the Senate gave final approval to the legislation Monday afternoon. The bill would impose only civil fines, rather than criminal sanctions, on those caught with less than 10 grams of the drug.

At least 24 other states now have either decriminalized the use of marijuana, approved it for medicinal purposes or legalized it outright, according to a study by the Pew Research Center for the People & the Press.

"As a young prosecutor, I once thought that decriminalizing the possession of marijuana might undermine the public will necessary to combat drug violence and improve public safety," O'Malley said in a statement. "I now think that [it] is an acknowledgment of the low priority that our courts, our prosecutors, our police and the vast majority of citizens already attach to this transgression of public order and public health."
