Kansas hasn't decided whether to join a lawsuit filed by other states against Colorado over its legalization of marijuana.
Spokeswoman Jennifer Rapp said Friday that Kansas Attorney General Derek Schmidt has been considering legal action against Colorado for months.
However, Rapp says Schmidt's office is still weighing its options.
Nebraska and Oklahoma filed a lawsuit Thursday with the U.S. Supreme Court, asking it to declare Colorado's legalization of marijuana unconstitutional. They argue it's a public safety issue.
They want to keep Colorado from enforcing an initiative approved by voters in 2012 to legalize marijuana, despite federal laws against it.
