Where you can legally use cannabis in Chicago and Illinois, and how much you can buy

Walk out of a dispensary on Milwaukee Avenue with a sealed bag and the city around you turns into a map of places you cannot open it. The sidewalk is out. So is the bench at the bus stop, the park two blocks over and the car at the curb, parked or running. Under the Cannabis Regulation and Tax Act (410 ILCS 705/10-35) and the City of Chicago's own guidance, an adult aged 21 or over may use cannabis on private property where the owner allows it, and at a business holding a local on-premises consumption license. That is the whole list. As for buying: since 12 June 2026 a resident may possess 60 grams of flower, a visitor 30.

The state law reads like a list of exceptions to a permission. Section 10-35 forbids use in "any public place", which it defines as anywhere a person could reasonably be observed by others, and it names government buildings and parks. It forbids use in any motor vehicle. Chicago adds the detail a visitor needs: streets, parks and the area next to a licensed dispensary all count as public, and a vehicle counts whether or not the engine is on. None of this changed in 2026. What changed, in June, was how much you may carry home.

The law allows for one, and that is as far as the public record takes us. Illinois leaves consumption lounges to local government: under the Act a city or village may authorize on-site use at a dispensary or at a standalone retail tobacco store, and the state itself issues no lounge license. Chicago's cannabis guidance says use is permitted at a business holding an on-premises consumption license. On 13 October 2026 we searched the city's and the state's published pages for a list of Chicago businesses holding that license and found none, so we name none here. If a venue tells you it is licensed, ask to see the license.

Springfield has been asked to settle the question statewide. House Bill 3513, filed in February 2025, would create an On-Premise Cannabis Consumption Act and let counties and municipalities license "cannabis hospitality venues", kept at least 500 feet from a school. We found no record of it passing. Until something like it does, the visitor who wants to smoke somewhere other than a friend's back porch is asking a question the city has answered in principle and not, as far as we can find, in practice.

A hotel is private property, which sounds like good news until you read Section 10-35(c): nothing in the Act stops a private business from restricting or banning cannabis on its premises, parking lots included. The Smoke Free Illinois Act applies to smoking cannabis exactly as it applies to tobacco. So the hotel decides, and its house rules are the rules that bind you. Read them before you light anything, and remember that the smoke-free law is about smoke; a hotel's own policy can reach further.

A car is simpler, because the answer is always no. Using cannabis in a motor vehicle is prohibited outright. Carrying it is allowed, on terms: the Illinois Vehicle Code (625 ILCS 5/11-502.15) requires cannabis in a vehicle to be in a secured, sealed or resealable, odor-proof, child-resistant container that the driver and passengers cannot reach. The odor-proof clause has its critics. In April 2025 the Illinois Senate voted 33 to 20 for Senate Bill 42, which would have dropped it and barred stops based on cannabis odor alone; in May 2025 the bill went back to the House Rules Committee, and the requirement stands. Put the bag in the trunk.

The airport is where state law ends. The Transportation Security Administration says marijuana remains illegal under federal law, apart from hemp products at or under 0.3% THC and FDA-approved drugs, and that its officers, who do not search for drugs, refer any they find to law enforcement. Illinois's own cannabis regulator says cannabis should not be taken across state lines, and Chicago's guidance says cannabis bought in Illinois cannot be transported to another state. A visitor flying home from O'Hare or Midway should plan to finish, or leave behind, what they bought.

On 12 June 2026 Governor Pritzker signed Senate Bill 3222, now Public Act 104-0463, and the possession limits in 410 ILCS 705/10-10 doubled on signing. A resident aged 21 or over may now possess 60 grams of cannabis flower, 10 grams of concentrate and cannabis-infused products containing no more than 1,000 milligrams of THC. A non-resident aged 21 or over may possess 30 grams, 5 grams and 500 milligrams. Older figures, half of these, still circulate, including on some state pages we read on 13 October 2026; the statute is the text that counts.

Two clauses matter more than the numbers. The limits are cumulative, so a resident may hold all three at once: 60 grams of flower and 10 grams of concentrate and 1,000 milligrams of edibles. And the Act forbids obtaining from a dispensary any amount that would take you over the limit, which means what is already in your bag counts against what you buy. Edibles are measured in milligrams of THC, not in the weight of the chocolate. The visitor limit is the one that moved most in practice: 30 grams is a little over an ounce, where 15 was barely half of one.

The first thing that happens at an Illinois counter is that somebody scans your ID. The Act requires a dispensary to refuse a sale unless the buyer shows valid identification proving they are 21 or older, and the state's rules require the card to be scanned electronically where it can be. It must be current and carry a photograph and a date of birth. The scan is for age and validity only: the Act says the data may not be retained, used or shared except as the Act allows, and the state may not require a buyer to hand over personal information beyond that ID.

Residency is where people get caught out. The resident limit follows proof of Illinois residence, and the state's guidance to dispensaries says extra identification may be needed to prove it. A new Chicagoan still carrying a Wisconsin or Indiana license may be held to the visitor limit unless they can prove residence some other way. The same guidance tells stores not to treat an international driving permit or a student card as government ID; a passport or a consular card is the safer thing to bring from abroad.

We read the menus of 23 Illinois stores every morning around 8 AM CT, 15 of them inside the city limits. The deals below are drawn from those menus, and each store page shows what that shop is charging today.
