An Illinois-licensed health care professional can certify your qualifying condition for the IDPH Medical Cannabis Patient Program. Here's what changes when you cross into Iowa.
Illinois's Medical Cannabis Patient Program is run by the Illinois Department of Public Health (IDPH).
An Illinois-licensed physician, APRN, or physician assistant certifies your qualifying condition.
Apply online with ID and proof of Illinois residency, and choose a 1-, 2-, or 3-year card.
Shop at dispensaries that serve medical patients while IDPH reviews your application.
Show your registry card on your phone or in print, with photo ID.
The Quad Cities straddle the Mississippi. Moline and Rock Island are in Illinois; Davenport and Bettendorf are in Iowa, where the rules are far stricter.
Iowa doesn't recognize Illinois medical cards. Iowa law applies the moment you cross into Davenport or Bettendorf.
Iowa allows only limited products for registered Iowa patients — no flower or edibles, and up to 4.5 grams of THC per 90 days.
In Iowa, possessing marijuana outside the state program is a criminal offense, even in small amounts.
Rock Island Arsenal is a federal Army installation. Federal rules apply there, whatever your state card says.
Simple rule: keep it on the Illinois side, and never bring it to Arsenal Island. Carrying cannabis across state lines can also violate federal law.

Home grow for Illinois patients 21+
Patient state tax rate, with no cannabis excise tax

IDPH recognizes dozens of debilitating conditions. A sample:
Also: adults 21+ with a condition for which an opioid has been or could be prescribed can use the separate Opioid Alternative Patient Program, with renewable 90-day certifications. See the full list from IDPH.
Moline's dispensaries are along Avenue of the Cities and near John Deere Road. At least one describes itself as recreational only, so confirm a store serves medical patients before you go — that's how you get the patient tax rate.
The state's dispensary list highlights the ones that serve patients.

“I work in Davenport and live in Moline. My medicine never leaves the Illinois side — it's the easiest rule I follow.”
— Tony M., Moline“I checked which stores served patients before my first visit. The tax difference showed up on my very first receipt.”
— Kristin D., East MolineNo. Iowa doesn't recognize Illinois cards, Iowa's program doesn't allow flower or edibles, and crossing state lines can violate federal law.
The Arsenal is federal property, where federal rules apply. Federal workplaces also often have their own drug-testing rules — check with your employer.
No. IDPH registration requires Illinois residency.
A condition on IDPH's list, certified by an Illinois-licensed health care professional. Adults 21+ may also qualify through the Opioid Alternative Patient Program.
After you apply, IDPH issues a provisional registration so you can shop at medical dispensaries while it reviews your application.

$50 for one year, $100 for two, or $125 for three — or $25, $50, or $75 for qualifying veterans and SSI or SSDI recipients.
Registered patients skip the 10–25% cannabis excise tax and pay a 1% state rate — at dispensaries that serve patients.
No. The health care professional's fee is separate from the state fee.
Moline sits on the Mississippi in Rock Island County, one of the four core Quad Cities. It's home to John Deere's world headquarters, a busy riverfront, and the arena at The MARK, with Rock Island Arsenal just offshore. Moline residents follow the same statewide rules as every patient in Illinois's Medical Cannabis Patient Program.
The medical program operates under the Compassionate Use of Medical Cannabis Program Act (410 ILCS 130). Adult-use sales for those 21 and older began in 2020 under the Cannabis Regulation and Tax Act.
Public use is prohibited and driving impaired is illegal. Federally, state-licensed medical cannabis moved to Schedule III in 2026, but it remains a controlled substance, and adult-use cannabis remains in Schedule I. See IDPH for current rules.
