A state lawmaker on Monday is scheduled to unveil legislation that would legalize, regulate, and tax recreational marijuana in New Jersey. 

State Sen. Nicholas Scutari (D-Union) will formally announce the Democratic-sponsored measure noon at Monday at a news conference at the Statehouse in Trenton.

Medical marijuana is already legal in the state. But if this bill becomes law, New Jersey would become the ninth state to legalize pot -- joining Alaska, California, Colorado, Maine, Massachusetts, Nevada, Oregon, and Washington, as well as the District of Columbia.

"The national trend is toward legalization," Scutari told NJ Advance Media on Friday. "It's absolutely necessary to save our neighborhoods from drug dealers. And we can use the tax revenue. And people are smoking it anyway."

The bill would not immediately legalize marijuana. It would still need to be passed by both houses of the state Legislature and signed by the governor to be enacted. 

Gov. Chris Christie, a Republican, is staunchly against marijuana, arguing that it's a "gateway drug" that can lead users to try harder substances. 

Earlier this month, Christie ripped into supporters of legal pot, saying Democrats who want to pass such legislation are willing to "poison our kids" to receive "blood money" from the tax money it will bring in. 

"This is beyond stupidity," he said during a speech in Princeton. 

But Scutari noted that Christie's final term is up in January, and a new governor will be elected in November. The front-runner is Democrat Phil Murphy, who is in favor of legalization. So are the other five Democratic candidates for governor. Republican candidates are split.

"We got to get the ball rolling and educate the legislators," said Scutari, chairman of the Senate's judiciary committee. "This is not something I can guarantee passage of right now. But we've got to work it so it will be ready for a new administration come January."

There is also the question of how the administration of President Donald Trump, a Republican, will approach marijuana. 

Technically, recreational marijuana is against federal law. But President Barack Obama's administration chose not to enforce it in states that legalized pot.

Now, proponents are worried because Trump's U.S. attorney general, Jeff Sessions, has said he's against it.

Scutari, who sponsored New Jersey's medical marijuana law, has been lobbying for the state to legalize recreational pot for years. 

He led a delegation of state legislators to Colorado in October to examine that state's legal marijuana program.
