Illinois Recreational Marijuana: Laws, Taxes, and Dispensary Information

What to Know About Recreational Marijuana in Illinois

Last updated: August 2026

Illinois legalized recreational marijuana for adults 21 and older, with legal adult-use sales beginning January 1, 2020. The state was the first in the country to legalize adult-use cannabis through its legislature rather than a voter ballot initiative.

How Much Recreational Cannabis Can You Have in Illinois?

As of June 12, 2026, Illinois residents age 21 and older can legally possess:

• 60 grams of cannabis flower
• 10 grams of cannabis concentrate
• 1,000 milligrams of THC in cannabis-infused products

Adults 21 and older who live outside Illinois can possess up to 30 grams of flower, 5 grams of concentrate, and 500 milligrams of THC in cannabis-infused products. These limits are cumulative, meaning you can possess products from each category up to that category’s legal limit.

Where Can You Legally Use Cannabis in Illinois?

Illinois recreational weed can generally be used on private property when the property owner allows it. Illinois law prohibits cannabis use in public places, motor vehicles, government property, and other restricted locations. Smoking cannabis is also subject to the Smoke-Free Illinois Act.

If you’re driving with cannabis purchased from a licensed dispensary, keep it in its original packaging inside a secured, sealed, odor-proof, child-resistant container. Cannabis cannot be used in a motor vehicle or transported across state lines.

How Much Is the Illinois Weed Tax?

The Illinois weed tax on adult-use cannabis depends partly on what you buy and its adjusted THC level. Illinois currently applies a Cannabis Purchaser Excise Tax of:

• 10% for cannabis at or below 35% adjusted THC
• 25% for cannabis above 35% adjusted THC
• 20% for cannabis-infused products

Adult-use purchases are also subject to Illinois’ 6.25% general merchandise tax, along with applicable local sales taxes and any cannabis-specific taxes imposed by the municipality or county. That means the total tax you pay can vary depending on the product and where you buy it.

Municipal cannabis taxes can reach 3%. County cannabis taxes can reach 3% within municipalities or 3.75% in unincorporated areas. Because local rates can change, check the Illinois Department of Revenue Tax Rate Finder for the current rate where you’re shopping.

Buying Recreational Marijuana in Illinois

If you’re 21 or older, you can buy Illinois recreational marijuana from a licensed dispensary with a valid, unexpired government-issued photo ID that shows your date of birth. You don’t need to live in Illinois to shop at a dispensary. Illinois law requires dispensaries to verify a recreational purchaser’s age and ID before completing the sale.

Buying from a licensed Illinois dispensary also means the cannabis comes through the state’s regulated market. If you want to shop with EarthMed, you can browse recreational menus for our Addison, Rosemont, and McHenry locations online before you visit.

Medical vs. Recreational Cannabis in Illinois

You don’t need a medical cannabis card to buy adult-use cannabis in Illinois once you’re 21. For registered medical cannabis patients, though, the rules and taxes differ. Medical cannabis is subject to Illinois’ 1% State Retailers’ Occupation Tax rate, with certain local transit taxes also applying. Adult-use cannabis is subject to the higher taxes explained above.

Registered qualifying medical cannabis patients also have rights that recreational customers don’t, including limited home cultivation under Illinois law.

Illinois Recreational Cannabis FAQs

Can I grow recreational marijuana at home in Illinois?

No. Illinois home cultivation is limited to registered patients who have qualifying medical cannabis conditions. Recreational customers cannot legally grow cannabis at home.

Can I give cannabis to another adult in Illinois?

Yes, Illinois allows adults 21 and older to give cannabis to another adult 21 or older as a genuine gift, as long as no money or other compensation is exchanged and possession limits are followed. Only licensed cannabis businesses may sell cannabis.

Does an Illinois dispensary keep my personal information when it scans my ID?

Illinois law limits what dispensaries may do with identification information. A dispensary may scan a government-issued ID to verify your age and the ID’s validity, but identifying information obtained through that process generally cannot be retained, used, shared, or disclosed except as authorized by law.
