Illinois Governor-elect J.B. Pritzker said he wants to legalize recreational marijuana use in Illinois immediately after being sworn in next year.

“That’s something we can work on nearly right away,” Pritzker told WFLD on Wednesday.

Pritzker also plans to look at vacating arrest records for individuals convicted of crimes involving marijuana.

“I definitely want to look at all those arrest records. If we’re going to legalize recreational marijuana, then we shouldn’t have all the, what I think are, challenges in our criminal justice system, you know, still existing, people sitting in prison for things that are currently legal,” Pritzker said.

Illinois does not have to vote to approve a measure to legalize marijuana: Pritzker can simply sign legislation passed by lawmakers in the General Assembly.

On Tuesday, the state of Michigan became the first state in the Midwest to legalize marijuana use for people over the age of 21, similar to alcohol.
