Recreational home growing is illegal in Illinois. Only a registered medical patient 21 or older may cultivate cannabis at home, capped at 5 plants per household. Adults 21+ may possess up to 30 grams of flower.
Illinois legalized recreational cannabis in 2020, but home cultivation was not part of it. Under the Cannabis Regulation and Tax Act (410 ILCS 705/10-5), only an Illinois resident 21 or older who is a registered qualifying patient under the Compassionate Use of Medical Cannabis Program Act may grow cannabis, limited to 5 plants taller than 5 inches per household, in a secure area not accessible to the public. A non-patient adult who grows 5 or fewer plants commits a civil law violation punishable by a fine up to $200, with the plants subject to seizure; larger grows bring criminal charges. Champaign and Urbana follow this state framework.
A non-patient who cultivates cannabis at home commits a civil law violation with a fine up to $200 for five plants or fewer; larger grows or sales are charged criminally under the Cannabis Control Act.
