Illinois Governor J.B. Pritzker signed a bill into law in June 2019 legalizing the recreational use of cannabis by adults, including retail sales beginning on Jan. 1, 2020. The following article covers Illinois' current cannabis laws with summaries of provisions under these laws.
As of Jan. 1, 2020, the cultivation and possession of a small amount of marijuana is legal in Illinois under the Cannabis Regulation and Tax Act. The state also allows the use of medical marijuana for eligible patients, who also are permitted to grow their own medicine. Non-medical users, however, may not cultivate their own cannabis.
Cannabis Legalization in Illinois
Illinois lawmakers became the first to legalize the adult (21 and over) use of cannabis through legislation, rather than ballot initiative. The law was enacted on Jan. 1, 2020, with licensed sellers providing the herb at the retail level.
The law allows Illinois residents age 21 and over to purchase up to one ounce of flower (dried herb) and up to five grams of cannabis concentrate (such as hashish or tincture). Illinois visitors are able to possess half those amounts. The law allows adults to consume cannabis either in their homes or at certain approved establishments. Businesses and landlords have the right to refuse its use on their properties.
Also, pre-legalization convictions for marijuana-related offenses (under 30 grams) are eligible for pardons as long as no violent crimes were committed. Cases will be reviewed by the Prisoner Review Board.
