Two states challenge Colorado marijuana legalization

LINCOLN, Neb. -- Nebraska and Oklahoma on Thursday asked the U.S. Supreme Court to declare Colorado's legalization of marijuana unconstitutional, saying the drug is being brought from Colorado into the neighboring states.

Nebraska Attorney General Jon Bruning said the states filed a lawsuit seeking a court order to prevent Colorado from enforcing the measure known as Amendment 64, which was approved by voters in 2012. The complaint says the measure runs afoul of federal law and violates the Constitution's supremacy clause, which says federal laws trump state laws.

"This contraband has been heavily trafficked into our state," Bruning said at a news conference in Lincoln. "While Colorado reaps millions from the sale of pot, Nebraska taxpayers have to bear the cost."

In a policy statement last year, the U.S. Justice Department noted it doesn't have the resources to police all violations of federal marijuana law.

It laid out eight federal law enforcement priorities that states need to protect if they want to authorize "marijuana-related conduct." They include keeping marijuana in-state -- something Oklahoma and Nebraska says Colorado has failed to do.

Oklahoma Attorney General Scott Pruitt said Colorado's decision has hindered his state's efforts to enforce its anti-marijuana laws.

"As the state's chief legal officer, the attorney general's office is taking this step to protect the health and safety of Oklahomans," Pruitt said in a statement.

Washington state also has legalized marijuana, but Bruning said Washington wasn't included in the lawsuit because it doesn't share a border with Nebraska or Oklahoma.

Colorado Attorney General John Suthers said the lawsuit was without merit but that he was not totally surprised by it because neighboring states have expressed concerns about Colorado marijuana crossing the border.

"However, it appears the plaintiffs' primary grievance stems from nonenforcement of federal laws regarding marijuana, as opposed to choices made by the voters of Colorado," Suthers said in a statement in which he said Colorado would vigorously defend its law.

Bruning, a Republican, blamed U.S. Attorney General Eric Holder for failing to enforce the federal law's ban on drugs in Colorado.

Brian Vicente, a Colorado attorney and legalization advocate who wrote Amendment 64, said the challenge is "political grandstanding" without merit. He said 23 states have enacted medical marijuana laws, and none have been overturned because of federal law.

"I think it shows they are on the wrong side of history," Vicente said. "Colorado voters passed this measure, and more and more states are passing these laws. If the attorney general has a problem with how federal laws are being enforced he should bring that up with the U.S. attorney."

But some law enforcement agencies in western Nebraska, along the Colorado border, say combating marijuana that's coming in from the neighboring state is a drain on their resources.

Scotts Bluff County Sheriff Mark Overman, in western Nebraska, said Colorado marijuana is extra potent, making it worth more in his region and giving sellers a greater financial incentive to do more business there.

"I think this is overdue, and I think other states should jump on board," Overman said. "I'm very frustrated. I take an oath of office, as does every other police officer in this country. I don't just get to pick and choose which laws I enforce."

There's no way to know exactly how much legal pot is leaving Colorado. But the Rocky Mountain High Intensity Drug Trafficking Area wrote in a recent report that the amount of Colorado pot seized on highways increased from 2,763 pounds between 2005 and 2008 to 3,690 pounds from 2009 to 2013. The weed was headed for at least 40 different states.

The report surveyed law enforcement agencies in Colorado and neighboring ones.
