Washington (CNN) Illinois is close to becoming the 11th state in the United States to legalize the purchase and possession of recreational marijuana.

The state's Senate on Wednesday passed legislation on a 38-17 vote that would allow adults to buy and possess small amounts of marijuana. The bill is currently being considered by the Democratic-majority House, which is facing a Friday deadline to get bills passed before adjournment.

The bill already has the support of Illinois' Democratic Gov. JB Pritzker, who had campaigned for the legalization of marijuana.

The bill would allow adults 21 and older to purchase and possess 30 grams of cannabis, five grams of cannabis concentrate, and cannbis-infused products containing no more than 500 milligrams of THC. Nonresidents will be able to purchase half of each of those amounts.

The measure would also pardon individuals with convictions for amounts of cannabis under 30 grams. State's attorneys or individuals would be able to petition a court to vacate convictions for cases with 500 grams possession. Supporters of the bill argue that the criminalization of marijuana has disproportionately impacted communities of color.
