The issue focused on legislation intended to legalize medical marijuana in Massachusetts. Lawmakers approved legislation last month that decriminalizes possession of small amounts of marijuana for adults 21 and older. Lawmakers then authorized Attorney General Martha Coakley to sue to challenge the constitutionality of the legislation.
