The nation's governors are taking a cautious approach on legalizing marijuana despite increasing support.
All the buzz over pot, some say, is just smoke.
Republicans and Democrats gathered for the National Governors Association meeting in Washington this weekend expressed broad concern for their children and public safety should legalized recreational marijuana use spread to their states.
States are watching closely as Colorado and Washington establish themselves as national pioneers after becoming the first states to approve recreational marijuana use in 2012. A group is hoping to do the same in Alaska this summer.
Colorado Gov. John Hickenlooper is warning other governors against rushing to follow his state's lead.
He says he's spoken to half a dozen governors with questions, and he's urging them to wait a year or two.
