New Jersey Gov. Chris Christie (R) says he is strongly against the legalization of marijuana, sending a signal that the legalization movement doesn't have a friend in him.

Asked by a caller on his "Ask the Governor" show about the steady progress of marijuana deregulation, the potential 2016 presidential candidate drew a line in the sand.

"You know when it may come down the road? When I'm gone," Christie said.

Christie noted a study released this week in the Journal of Neuroscience that said that even casual marijuana use affects that brain negatively.

"I am not going to be the governor who is going to tell our children and our young adults that marijuana use is OK, because it's not," Christie said. "I don't care about the tax money that may come from it, and I don't care, quite frankly, that people think it's inevitable."

Despite his comments, Christie has been among the leading voices calling for an end to the "war on drugs." He has also pushed to reform the state's drug sentencing policies -- a cause that is catching on among some Republican governors and senators.
