Yes, both medical and recreational cannabis are legal in Illinois. The Cannabis Regulation and Tax Act went into effect on January 1, 2020, allowing for the legal sale and use of cannabis for both medical and recreational purposes.
Under Illinois law, individuals over the age of 21 can legally possess and consume cannabis for recreational purposes. They can purchase up to 30 grams of cannabis flower, 5 grams of cannabis concentrate, or 500 milligrams of THC-infused products (such as edibles) from licensed dispensaries.
For medical cannabis patients, the law allows for the use of cannabis to treat a wide range of qualifying medical conditions. Patients must have a written certification from a physician to obtain medical cannabis, and they can purchase up to 2.5 ounces of cannabis every two weeks from licensed dispensaries.
