Nebraska Attorney General Jon Bruning and Oklahoma Attorney General Scott Pruitt have filed a lawsuit in the U.S. Supreme Court seeking a declaration that Colorado’s legalization of marijuana violates the United States Constitution. The two don’t say exactly how the law violates the constitution, but Bruning says “federal law undisputedly prohibits the production and sale of marijuana.” In a press release, the two say that Congress has continually enforced the principle that drugs are a threat to health and safety and the trafficking of drugs is a national, interstate problem. Colorado has created a system that legalizes, promotes and facilitates distribution of marijuana. The press release says the illegal products of this system are heavily trafficked into neighboring states, causing an unnecessary burden. The Medical Marijuana Industry Group has responded by pointing out lower crime statistics and lower teen use in Colorado as proof the system is working. They say if Nebraska and Oklahoma succeed in their lawsuit, they will put the violent criminal organizations back in charge.
