What happens next: if you qualify, the health care professional submits your certification to IDPH. You then register through the IDPH patient registry with ID and proof of Illinois residency, choose a 1-, 2-, or 3-year card ($50, $100, or $125; reduced for qualifying veterans and SSI/SSDI recipients), and receive provisional access while IDPH reviews your application. Shop only at dispensaries that serve medical patients.
