An Illinois-licensed health care professional can certify your qualifying condition for the IDPH Medical Cannabis Patient Program — with clear answers about Missouri and Scott Air Force Base.
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 Illinois dispensaries that serve medical patients while IDPH reviews your application.
Show your registry card on your phone or in print, with photo ID.
Belleville sits minutes from St. Louis, where adult-use cannabis is legal — and right next to Scott Air Force Base, where federal rules apply.
Missouri doesn't accept out-of-state medical cards, so there's no medical pricing or patient access for Illinois patients.
Anyone 21+ can buy adult-use cannabis in Missouri, paying Missouri's adult-use taxes like any other customer.
Missouri sells to people under 21 only through its own medical program, so Illinois patients under 21 can't buy there.
Carrying cannabis across the Mississippi, in either direction, can violate federal law.
Federal rules apply on base, whatever your state card says. Service members are subject to military drug policy, which prohibits marijuana use regardless of state law. Civilian employees and contractors should check their federal workplace and drug-testing rules.
Simple rule: get certified and shop in Illinois, keep it in Illinois, and never bring it on base.

Belleville's historic downtown square and fountain, ringed by shops and restaurants — lovely on an evening stroll.
“I work in St. Louis, but my card only matters on this side of the river. I buy here at the patient rate and keep it at home.”
— Denise H., Belleville“I'm a veteran with PTSD. I got the reduced state fee, and I never bring anything near the base.”
— Marcus W., O'FallonNo. Missouri doesn't accept out-of-state medical cards. Adults 21+ can buy there only as adult-use customers.

Belleville, the seat of St. Clair County, is one of Illinois's oldest cities, known for its German heritage, its historic Public Square and fountain, and its place in the St. Louis metro. Scott Air Force Base sits just to the east. Belleville 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.
