Illinois has now become the 11th state to officially legalize marijuana. The news was announced Tuesday after the state’s new Democratic governor signed a bill legalizing its use.

According to ABC News, the Illinois General Assembly passed a law, which legalized and regulated the production of marijuana on May 31st after Governor JB Pritzker campaigned about it. The legalization will officially go into effect on January 1, 2020.

Governor Pritzker said in a statement, “As the first state in the nation to fully legalize adult-use cannabis through the legislative process, Illinois exemplifies the best of democracy: a bipartisan and deep commitment to better the lives of all of our people.”

He continued, “Legalizing adult-use cannabis brings an important and overdue change to our state, and it’s the right thing to do. This legislation will clear the cannabis-related records of nonviolent offenders through an efficient combination of automatic expungement, gubernatorial pardon, and individual court action.”

Illinois now joins 10 other states and also the District of Columbia, which allows the legal use of marijuana.
