Illinois Marijuana Laws

The cultivation, trafficking, sale, or possession of marijuana is a crime in Illinois under the state's Controlled Substances Act. But while laws criminalizing cocain, heroin, and other hard drugs typically result in felony charges, Illinois marijuana laws are much more lax. For instance, possession of less than 2.5 grams of cannabis is a class C misdemeanor, punishable by a fine. The state also allows the use of medical marijuana for eligible patients as part of a pilot program slated to run through 2018.

Details about Illinois marijuana laws are listed and referenced in the table below. For more information, see Medical Marijuana Laws by State and FindLaw's Drug Charges section.
