BOSTON — A group supporting legalized use of recreational marijuana in Massachusetts said Friday that Gov. Charlie Baker and Boston Mayor Marty Walsh are being hypocritical by supporting more liquor licenses while opposing the pot initiative.

The Campaign to Regulate Marijuana Like Alcohol leveled the charge a day after Baker, Walsh and other top officials announced formation of a committee to fight a likely November ballot question that would allow Massachusetts residents 21 and older to possess up to 1 ounce of marijuana.

The group unveiled a poster outside the Statehouse showing the faces of Baker and Walsh, who is a recovering alcoholic, with a speech bubble that read: “Our Health Policy: Drink More Alcohol.”
