Illinois cannabis rules for visitors

Adults 21 and older who live in Illinois may possess up to 60 grams of cannabis flower, 10 grams of cannabis concentrate and 1,000 milligrams of THC in cannabis-infused products, and adults who live elsewhere may possess half that: 30 grams of flower, 5 grams of concentrate and 500 milligrams of THC (410 ILCS 705/10-10). The categories stack, so a person may hold up to the cap in each at once, but no one may obtain an amount from a dispensary that would push them past their limit. The figures doubled on June 12, 2026, when Public Act 104-463 took effect; some older state pages still print the 2020 numbers.

Bring valid, unexpired government ID with a photo and date of birth; Illinois sets no residency rule, and visitors buy under the lower non-resident limit (410 ILCS 705/10-10, 15-85). Use cannabis only on private property where the owner allows it: the Act bars use in any public place, which includes every park, beach and lakefront path run by the state or a local government, and in any motor vehicle, and Chicago fines public use $50 for a first offense (Municipal Code 7-24-099). Hotels may ban cannabis, at least 75 percent of hotel rooms are smoke-free by law, and dispensaries may not deliver. Flights out of O'Hare and Midway, federal land and trips across state lines fall under federal law, where adult-use marijuana remains Schedule I.

The regulator is the Illinois Department of Financial and Professional Regulation. Check any shop's license on the state license lookup before you buy.

Adults 21 and older who live in Illinois may possess up to 60 grams of cannabis flower, 10 grams of cannabis concentrate and 1,000 milligrams of THC in cannabis-infused products such as edibles and drinks. A visitor who lives in another state or country gets half: 30 grams of flower, 5 grams of concentrate and 500 milligrams of THC in infused products (410 ILCS 705/10-10). The state's Cannabis Regulation Oversight Office describes 60 grams as about 2 ounces and 30 grams as about 1 ounce.

The statute calls the limits cumulative, and the oversight office reads that to mean a person may hold a combination of flower, concentrate and infused products up to the cap in each category. The same numbers work as a purchase ceiling: no one may knowingly obtain an amount from a dispensary that would push them over their possession limit (410 ILCS 705/10-10). Each sale is entered into the State's cannabis electronic verification system with the amount and type of product dispensed (410 ILCS 705/15-85).

These limits are new. Public Act 104-463, signed June 12, 2026 and effective the same day, doubled every figure: residents rose from 30 grams, 5 grams and 500 milligrams, and visitors from 15 grams, 2.5 grams and 250 milligrams. IDFPR's June 23, 2026 fact sheet confirms the change. Some official pages lag behind: IDFPR's purchaser FAQ, last updated in 2023, still lists the old numbers, and the gifting answer on the oversight office's FAQ still cites 30 grams. The statute controls.

Gifts between adults 21 and older are legal as long as they are purely non-commercial and are not used to promote a sale, the oversight office says, and possession limits still apply to the person receiving them. Hemp is a separate track. The same Public Act creates an Illinois Hemp Act that takes effect November 12, 2026 and limits a final consumer hemp cannabinoid product to 0.4 milligrams of total THC per container.

You must be 21 or older, and a dispensary must refuse a sale unless you produce valid identification showing that you are at least 21 (410 ILCS 705/15-85). The ID must be valid and unexpired and must carry your photograph and date of birth. Before each sale the agent checks your age and the card's validity with an electronic reader or scanning device where the document can be scanned (410 ILCS 705/15-85, 10-20). Registered medical patients under 21 may buy only at a store licensed for medical sales.

Illinois does not require residency to buy. The statute sets a separate, lower possession limit for a person 21 or older 'who is not a resident of this State' (410 ILCS 705/10-10), which is the rule that lets visitors shop. The Act asks only for government-issued identification and does not publish a list of accepted documents or limit it to U.S. cards, so a valid foreign passport meets the text; the store's scanner and agent make the call in practice. Bring the original, not a photocopy.

Privacy rules limit what stores collect. IDFPR may not require a purchaser to give a dispensary personal information beyond government-issued identification to determine age, and a dispensary may not obtain and record personal information about a purchaser without consent; data from the ID scan may be used only as the Act allows (410 ILCS 705/10-20). IDFPR's consumer guide says every dispensary checks the identification of every person who enters and may check it more than once during a visit.

Underage attempts carry real penalties. A person under 21 who offers false or borrowed evidence of age to buy cannabis or to get into a store commits a Class A misdemeanor, and the Secretary of State may suspend or revoke driving privileges (410 ILCS 705/10-20). Possession by anyone under 21 is a civil law violation with a fine of $100 to $200 (410 ILCS 705/10-15, 720 ILCS 550/4), and a parent who knowingly lets underage guests use cannabis at home commits a Class A misdemeanor with a fine of at least $500 (410 ILCS 705/10-15).

Private property, with the owner's permission, is the only reliably legal place. The Act bars using cannabis in any public place, in any motor vehicle, on school grounds or a school bus, in a correctional facility, in a home used for licensed child care, and knowingly near anyone under 21 who is not a registered patient (410 ILCS 705/10-35). It also bars smoking cannabis anywhere the Smoke Free Illinois Act bans smoking, and it lets any private business restrict or prohibit cannabis on its property, including parking areas.

'Public place' is defined broadly: any place where a person could reasonably be expected to be observed by others, all parts of buildings owned or leased by the State or a local government, and all areas in a park, recreation area, wildlife area or playground owned, leased or managed by the State or a local government (410 ILCS 705/10-35). A private residence is excluded unless it is used for licensed child care or similar care. That covers Chicago's beaches and the 18-mile Lakefront Trail, run by the Chicago Park District along the city's 26 miles of lakefront. A balcony, porch or yard in plain view of neighbors or the street may still count as public.

The Smoke Free Illinois Act adds an indoor layer. No one may smoke in a public place, in a place of employment or within 15 feet of an entrance to either (410 ILCS 82/15), and smoking is defined to include any lighted weed or herbs and the use of an electronic cigarette (410 ILCS 82/10). The Act's list of public places includes bars, restaurants, stores, arenas, lobbies and convention facilities, so vaping indoors is no workaround.

Chicago enforces the same lines with its own fines. Its code makes it unlawful to use cannabis in any public place or any motor vehicle, or to smoke it where the Smoke Free Illinois Act forbids smoking, and the November 2019 amendment set a fine of $50 for a first offense and $100 for a second or later violation within 30 days, or community service or a drug education program instead (Chicago Municipal Code 7-24-099). Each violation counts as a separate offense.

Only if the hotel allows it, and smoking it is usually off the table. No Illinois statute bans cannabis in a guest room, and a closed room is not a place where you would reasonably expect to be observed, the Act's test for a public place (410 ILCS 705/10-35). But the Act lets any private business restrict or prohibit the use of cannabis on its property (410 ILCS 705/10-35), so a hotel's no-cannabis policy is enforceable as a condition of your stay. Check the house rules before you book.

Smoking runs into the Smoke Free Illinois Act. Its definition of public place includes lobbies and no less than 75 percent of the sleeping rooms rented to guests in any hotel, motel, resort, inn, bed and breakfast or similar lodging (410 ILCS 82/10). A hotel may designate no more than 25 percent of its rooms as smoking rooms, grouped together on each floor (410 ILCS 82/35), and smoking under the Act includes vaping (410 ILCS 82/10). Even in a designated smoking room, the hotel's own cannabis policy still applies.

Common areas are public places. Lobbies, hallways, pools, hotel bars and restaurants are places where you can expect to be seen, so using cannabis there breaks the Act (410 ILCS 705/10-35), and inside Chicago it draws the city's $50 fine for a first offense (Chicago Municipal Code 7-24-099). Edibles avoid the smoke rules, but not the hotel's policy or the public-place rule, so keep them in the room.

Vacation rentals work the same way. A short-term rental is private property run as a business, so the owner's rules and the listing terms govern, and the owner may prohibit cannabis (410 ILCS 705/10-35). Do not plan on delivery to your room either: Illinois dispensaries may not transport cannabis to residences or other locations where purchasers may be, and may not let anyone other than their own agents deliver it (410 ILCS 705/15-70). Pickup at the store is the only option.

Illinois allows lounges only where local government says yes. The Act lets a city, village or county authorize on-premises consumption at a dispensary or a retail tobacco store, and a site so authorized is not a public place under the Smoke Free Illinois Act (410 ILCS 705/55-25). The state does not issue lounge licenses itself: IDFPR's purchaser FAQ says the Department does not license on-site consumption lounges, and the oversight office's FAQ points visitors to local authorization.

Chicago has not passed a lounge ordinance. A 2019 proposal to add a new Chapter 4-52 licensing cannabis consumption business establishments and to amend the city's Clean Indoor Air chapter, O2019-9399, is marked Failed to Pass as of May 24, 2023 in the City Clerk's records, and the Clerk's list of cannabis matters shows no later lounge ordinance passed. We found no Chicago authorization for on-site consumption as of October 16, 2026, so plan on no legal lounge inside city limits.

Where a town has opted in, IDFPR's rules set the floor. A dispensary may run a lounge only with proof of local authorization and Department approval, at the dispensary's address or a contiguous building, in an area separated from the rest of the store by a door that locks. Entry is limited to adults 21 and older after an ID check, the lounge may not hold a liquor or gaming license, food is allowed with local permits, and ventilation must remove visible smoke and odor at the property line (68 Ill. Adm. Code 1291.340).

The Smoke Free Illinois Act exempts such a dispensary only if the smoking area is specially designated, limited to people 21 or older and kept behind a locked door or barrier (410 ILCS 82/35). We could not confirm from any municipality's own website which Illinois towns currently authorize a lounge, so check the town's ordinance and ask the dispensary whether IDFPR has approved its lounge before planning a visit around one.

No one may use cannabis in a motor vehicle in Illinois, driver or passenger (410 ILCS 705/10-35), and the Vehicle Code separately bars a driver from using it in the passenger area of any vehicle on a highway (625 ILCS 5/11-502.15). That covers a rental car, a taxi and an Uber or Lyft. In Chicago, using cannabis in any motor vehicle also carries the city's fine of $50 for a first offense (Chicago Municipal Code 7-24-099).

Carrying it has rules too. A driver may possess cannabis anywhere in the vehicle, and a passenger in the passenger area, only in a secured, sealed or resealable, odor-proof, child-resistant container that is inaccessible; a knowing violation is a Class A misdemeanor, punishable by less than a year in jail and a fine of up to $2,500 (625 ILCS 5/11-502.15, 730 ILCS 5/5-4.5-55). Since June 12, 2026 the inaccessible part does not apply to cannabis bought from a licensed dispensary that stays in its secured, sealed, odor-proof, child-resistant original packaging (410 ILCS 705/15-85).

Driving under the influence of cannabis is a DUI, and Illinois also sets a THC level: 5 nanograms or more of delta-9-THC per milliliter of whole blood, or 10 nanograms per milliliter of another bodily substance, within 2 hours of driving or being in actual physical control of a vehicle (625 ILCS 5/11-501, 11-501.2). Officers may use validated roadside chemical tests and standardized field sobriety tests in cannabis cases. A registered medical patient is exempt from the THC-level rule unless impaired, and lawful use is never a defense.

A first DUI is a Class A misdemeanor (625 ILCS 5/11-501), and a refusal to take roadside cannabis tests is admissible as evidence (625 ILCS 5/11-501.2). The oversight office warns that edibles may take 30 minutes or more to be felt and that many people do not feel the full effect for 2 to 4 hours, so settle the ride home before you consume. Stores may now offer drive-through and curbside pickup once IDFPR approves the setup (410 ILCS 705/15-85), so the packaging rule applies from the moment the bag is handed over.

Plan to reach the airport with none. O'Hare and Midway, both run by the Chicago Department of Aviation, are places where you can expect to be seen, which makes their terminals, garages and curbs public places under the Act, so using cannabis there is barred (410 ILCS 705/10-35), and Chicago's public-use fine applies (Chicago Municipal Code 7-24-099). We found no page on the airports' own website describing cannabis rules or disposal boxes, so do not count on a place to leave it.

The flight is governed by federal law. TSA says its officers do not search for illegal drugs, but if any illegal substance is discovered during screening, TSA will refer the matter to a law enforcement officer, and the final decision on any item rests with the TSA officer. The FAA's 2022 compliance letter calls marijuana a Schedule I controlled substance and says its cultivation, manufacturing and distribution are prohibited on federally obligated airport property regardless of state law. Federal simple possession carries up to a year in prison and a minimum $1,000 fine (21 U.S.C. 844).

Illinois protection stops at the state line, and the oversight office says cannabis should not be transported across state lines. In Wisconsin, possessing THC without a prescription is punishable by a fine of up to $1,000, up to 6 months in jail or both for a first conviction, and is a Class I felony for a second (Wis. Stat. 961.41(3g)(e)). Indiana borders Chicago's southeast suburbs and holds the Indiana Dunes; its code could not be read for this guide, so its penalties are not stated here.

Missouri legalized adult use in its constitution: adults 21 and older may purchase, possess and transport 3 ounces or less of dried, unprocessed marijuana or its equivalent (Missouri Constitution, Article XIV, Section 2). That does not make the drive legal. Carrying cannabis from Illinois into Missouri still moves it across a state line, and under federal law, adult-use marijuana outside a state medical license remains a Schedule I controlled substance (DEA final rule, April 28, 2026; 21 U.S.C. 844).

No. Illinois's oversight office says cannabis is not permitted on federal property, including military bases, federal parks and federal buildings, and its FAQ lists federal property among the places where possession is prohibited. Federal regulations bar possession of a controlled substance in National Park Service units (36 CFR 2.35), and simple possession under federal law carries up to a year in prison and a minimum $1,000 fine for a first offense (21 U.S.C. 844). State legalization offers no cover on federal ground.

The Park Service sites most reachable from Chicago are Pullman National Historical Park in the city, Lincoln Home National Historic Site in Springfield and Indiana Dunes National Park across the Indiana line, whose laws and policies page points visitors to Title 36 of the Code of Federal Regulations and the Superintendent's Compendium. Because Indiana Dunes sits in Indiana, cannabis bought in Illinois and carried there has also crossed a state line.

The 2026 federal rescheduling does not change this. A Drug Enforcement Administration final rule effective April 28, 2026 placed FDA-approved drug products containing marijuana, and marijuana subject to a state-issued license to manufacture, distribute or dispense it for medical purposes, in Schedule III. The rule states that any other form of marijuana remains a Schedule I controlled substance, which is where adult-use purchases from Illinois dispensaries fall.

State parks are not federal, but they are not open for use either. The Act counts all areas of any park, recreation area or wildlife area owned, leased or managed by the State or a unit of local government as public places (410 ILCS 705/10-35), so use is barred in state parks, county forest preserves and city parks alike. This guide does not describe tribal land rules, because no tribal government or Interior Department source on Illinois tribal land could be read.

No. Illinois dispensaries may not transport cannabis to residences or other locations where purchasers may be for delivery, and may not let anyone who is not one of their dispensing organization agents deliver or transport cannabis to purchasers (410 ILCS 705/15-70). The only exception in the statute is the pickup area described below. A website or app that offers to bring cannabis to a hotel, home or office is not making a licensed Illinois delivery, because the Act authorizes none.

What changed in 2026 is pickup. Since June 12, 2026, a dispensary may offer pickup or drive-through service (410 ILCS 705/15-85), dispensing from a drive-through window or from a pickup location in close proximity to its restricted access area, defined as an area contiguous to the dispensary's real property, such as a sidewalk or parking lot (410 ILCS 705/15-100). The store must confirm the same age and ID requirements as an in-store sale first, and IDFPR's fact sheet says stores need the Department's review and approval before offering either service.

The sale still happens at the store. The agent verifies age with an electronic ID scan and records the sale in the State's verification system (410 ILCS 705/15-85), and a visitor's order counts against the non-resident limit of 30 grams of flower, 5 grams of concentrate and 500 milligrams of THC (410 ILCS 705/10-10). Store hours may now run from 6 a.m. to 2 a.m. local time where local zoning allows, up from a 10 p.m. close (410 ILCS 705/15-70).

Only if you are a registered medical patient who lives in Illinois. An Illinois resident 21 or older who is registered under the Compassionate Use of Medical Cannabis Program Act may grow up to 5 plants taller than 5 inches per household, and 'resident' means domiciled in Illinois for 30 days before cultivating (410 ILCS 705/10-5). Visitors and adult-use customers may not grow, and the oversight office's FAQ says the same: only registered qualifying medical cannabis patients may grow, up to 5 plants.

The patient rules are specific. Plants must be in an enclosed, locked space, out of ordinary public view, on residential property the grower lawfully possesses or with the owner's consent, and a landlord may prohibit cultivation by a tenant. No dwelling or property may hold more than 5 plants at once, and only resident patients, or an agent during brief absences, may tend them (410 ILCS 705/10-5). Patients may buy seeds from dispensaries, and since June 12, 2026 clones as well (410 ILCS 705/10-5, 15-70).

Growing without that status is an offense under the Cannabis Control Act: 5 plants or fewer is a civil violation with a fine of $100 to $200, and 6 to 20 plants is a Class 4 felony, which carries 1 to 3 years in prison and a fine of up to $25,000 (720 ILCS 550/8, 730 ILCS 5/5-4.5-45, 5-4.5-50). A patient who grows more than the allowed number or sells or gives away homegrown cannabis loses home cultivation privileges and faces the same penalties (410 ILCS 705/10-5).

Chicago adds a local wrinkle. In a city of more than 500,000 people, voters in a precinct may petition for an ordinance making it a restricted cannabis zone that prohibits home cultivation, cannabis businesses or both (410 ILCS 705/55-28), and the City Clerk's records show Chicago precincts designated this way, at least one of them expressly barring home cultivation. A Chicago patient should check the precinct before planting anything.

Illinois taxes adult-use cannabis by product type. The cannabis purchaser excise tax is 10 percent of the purchase price for cannabis other than infused products with an adjusted delta-9-THC level at or below 35 percent, 25 percent for such cannabis above 35 percent, and 20 percent for cannabis-infused products such as edibles (410 ILCS 705/65-10). The adjusted level adds the delta-9-THC percentage to 0.877 times the THCA percentage (410 ILCS 705/65-5), and the Department of Revenue says concentrates and vapes are taxed by THC level, not at the 20 percent rate.

Sales tax comes on top. Adult-use cannabis pays the 6.25 percent state Retailers' Occupation Tax and local sales taxes at the general merchandise rate, plus any municipal cannabis tax of up to 3 percent and a county cannabis tax of up to 3 percent inside a municipality or 3.75 percent in unincorporated areas, all administered by the Department of Revenue. A separate 7 percent cultivation privilege tax on a grower's first sale is the cultivator's obligation, not the shopper's (410 ILCS 705/60-10).

In Chicago both local cannabis taxes apply: the city's 3 percent on gross receipts (Chicago Municipal Code 3-51-030) and Cook County's 3 percent at any location in the county (Cook County Code 74-862), both collected since July 1, 2020. The Department of Revenue's rate file puts the total sales tax on adult-use cannabis in Chicago at 16.50 percent from August 1, 2026, up from 16.25 percent, against 10.50 percent on general merchandise. A pre-roll under 35 percent THC therefore carries the 10 percent excise plus 16.50 percent in sales taxes.

Totals differ by town. The same file lists 14.50 percent on adult-use cannabis in the Kane County part of Aurora, 14.00 percent in the Will County part of Naperville and 14.75 percent in Rockford, while some locations in business districts are priced by address. Medical cannabis is taxed at the lower qualifying food and drug rate, 2.50 percent in Chicago, and is exempt from the excise and the local cannabis taxes (410 ILCS 705/65-10). From September 10, 2026, adult-use stores may opt into a medical license to sell to patients at the medical rate (IDFPR).

No. Illinois's medical program is run by the Department of Public Health, which says it issues registry cards to Illinois residents who meet program requirements, and the Opioid Alternative Patient Program is limited by statute to Illinois residents 21 and older (410 ILCS 130/62). We found no provision honoring another state's card. A visiting patient buys as an adult-use customer instead: 21 or older, under the non-resident limit, and paying adult-use taxes (410 ILCS 705/10-10).

For residents, the program is broad. A patient's adequate medical supply is 2.5 ounces of usable cannabis per 14 days, with a waiver available when a certifying health care professional states in writing that 2.5 ounces is not enough (410 ILCS 705/1-10). An applicant who submits a completed online application with a written certification receives a provisional registration for 90 days, during which a dispensary may sell up to 2.5 ounces per 14 days (410 ILCS 130/55). Registered patients under 21 may buy at stores licensed for medical sales (410 ILCS 705/15-85).

Public Act 104-463 reshaped how patients shop. From September 10, 2026, any adult-use dispensary with an active license in good standing may opt into a medical dispensary license that lets it sell to patients at the medical tax rate up to their allotment, and the law bars later separating the two licenses (IDFPR SB3222 fact sheet). Products sold to patients must carry a federally mandated warning label applied before sale. On IDFPR's October 7, 2026 list, 169 of the 289 active adult-use licenses also show a medical dispensary credential.

The program dates to 2013: the Department of Public Health says Illinois became the 20th state to authorize medical cannabis cultivation and dispensing in August 2013, and the law now carries the title Compassionate Use of Medical Cannabis Program Act (410 ILCS 130/1). Since June 22, 2021 the Department no longer mails cards; patients print or download them from their online account. Medical purchases also skip the purchaser excise tax and the local cannabis taxes (410 ILCS 705/65-10).

Most visitor trouble is local or misdemeanor-level. Using cannabis in public or in a vehicle in Chicago brings a fine of $50 for a first offense and $100 for a repeat within 30 days (Chicago Municipal Code 7-24-099). Carrying cannabis in a vehicle outside a sealed, odor-proof, child-resistant container, or a driver using it in the passenger area, is a Class A misdemeanor, punishable by less than a year in jail and a fine of up to $2,500 (625 ILCS 5/11-502.15, 730 ILCS 5/5-4.5-55). A first DUI is also a Class A misdemeanor (625 ILCS 5/11-501).

Going over the limit removes the Act's protection, and the Cannabis Control Act takes over by weight: 10 grams or less is a civil violation with a $100 to $200 fine; more than 10 and up to 60 grams is a Class B misdemeanor, punishable by up to 6 months in jail and a $1,500 fine; more than 60 and up to 100 grams is a Class A misdemeanor; and more than 100 and up to 500 grams is a Class 4 felony (720 ILCS 550/4, 730 ILCS 5/5-4.5-60). Public Act 104-463 moved the 30-gram break points to 60 on June 12, 2026.

Selling is treated more harshly than possessing. Manufacturing, delivering or possessing with intent to deliver 2.5 grams or less is a Class B misdemeanor, more than 10 and up to 60 grams is a Class 4 felony, and the class rises with weight from there (720 ILCS 550/5). Nothing in the Act permits transferring cannabis to anyone under 21, and a parent who knowingly allows underage guests to use cannabis at home commits a Class A misdemeanor with a minimum $500 fine (410 ILCS 705/10-15).

Under-21 possession is a civil law violation (410 ILCS 705/10-15), and using false identification to buy is a Class A misdemeanor that can cost a driver's license (410 ILCS 705/10-20). In Chicago, a vehicle used to buy or sell cannabis unlawfully can be impounded, with a $2,000 administrative penalty plus towing and storage fees, or $3,000 within 500 feet of a public park or school (Chicago Municipal Code 7-24-225). Buying from an unlicensed seller can therefore cost the car as well.

Check the name against IDFPR's list. The Department's Combined License List, updated October 7, 2026, counts 289 active adult-use dispensing organization licenses, each with the license holder, the store's trade name, address and phone, issuance date and a credential number ending in AUDO; stores that also hold a medical credential show a second number ending in DISP. The state oversight office also runs a dispensary map, updated as of October 8, 2026, and IDFPR offers a license look-up.

A licensed store looks a certain way. IDFPR's consumer guide says every dispensary displays an IDFPR-issued license, checks the identification of everyone who enters, keeps a locked door between the entrance and the sales area that only staff can open, and has opaque or tinted exterior windows. Flower is not on display, no nicotine is sold, and products are labeled and tested by a lab certified by the Department of Agriculture. Since June 12, 2026 agents may show their badge electronically on request instead of wearing it (IDFPR SB3222 fact sheet).

Hours and pickup changed in 2026. A dispensary may now operate between 6 a.m. and 2 a.m. local time, subject to local zoning, where the closing cap had been 10 p.m. (410 ILCS 705/15-70), and may offer approved drive-through or curbside pickup (410 ILCS 705/15-85). Stores may not dispense from vending machines, deliver to homes or hotels, or sell cannabis items bundled for one price, and each cannabis item must be listed separately by quantity and price on the receipt (410 ILCS 705/15-70).

Hemp shops are not dispensaries. Smoke shops and gas stations selling hemp-derived THC are not licensed dispensing organizations and do not appear on IDFPR's list, and from November 12, 2026 the new Illinois Hemp Act caps a final consumer hemp cannabinoid product at 0.4 milligrams of total THC per container (Public Act 104-463). The oversight office says only licensed cannabis businesses may sell cannabis, so a seller who is not on the list is outside the Act's protection.
