New Jersey probably looks a lot like home to the Denver Broncos. The billboards, anyway.

The Marijuana Policy Project, one of the main groups behind the push to legalize marijuana possession in Colorado, posted advertisements on billboards near Mile High Stadium before the first game of the Broncos’ season on Sept. 5.

Now the group has spent $5,000 to rent several 60-foot-wide billboards in New Jersey, within easy driving distance of MetLife Stadium, where the Broncos will play the Seattle Seahawks in Super Bowl XLVIII on Sunday. Three of the billboards face Interstate 78 near the New Jersey Turnpike toll plaza in Newark, Route 495 leading to the Lincoln Tunnel west of Routes 1 and 9 in North Bergen, and Interstate 80 near the turnpike in Hackensack. The others are on the Garden State Parkway near the Raritan toll plaza north of Sayreville.

The message is directed at the National Football League, just as it was in Denver, and is repeated in a petition the marijuana group plans to deliver to the N.F.L. on Wednesday. “Why are players punished for making the safer choice to use marijuana instead of alcohol?” asked Mason Tvert, a spokesman for the group. “In Colorado and Washington State, this is now a legal product, and the N.F.L. has no legitimate reason to be policing marijuana use by players.”
