What OAPP is
The Opioid Alternative Patient Program lets an Illinois resident 21 or older buy medical cannabis for 90 days at a time if they have a medical condition for which an opioid has been, or could be, prescribed. A physician licensed in Illinois certifies it. Each 90-day registration costs $10 and can be renewed.
The legislature created the program in Public Act 100-1114, signed August 28, 2018, and it launched on January 31, 2019. It is still active. IDPH's FY24 annual report counted 1,093 OAPP participants enrolled that year, so it's a small program next to the regular registry.
OAPP next to the regular card
| OAPP | Regular medical card (MCPP) | |
|---|---|---|
| Who qualifies | Condition for which an opioid has been or could be prescribed | One of 58 listed conditions, or terminal illness |
| Minimum age | 21 | 18 (minors through a caregiver) |
| Who certifies | Illinois-licensed physician only | Illinois physician, APRN or PA registered with IDPH |
| Registration length | 90 days | 1, 2 or 3 years |
| Fee | $10 per 90 days | $50, $100 or $125 |
| Purchase limit | 2.5 oz per 14 days | 2.5 oz per 14 days |
| Residency | Illinois residents | Illinois residents |
On price alone, four OAPP periods cost $40 a year against $50 for a one-year card. The $10 difference buys you three fewer renewals. If your condition is on the regular qualifying conditions list, the regular card is usually the simpler choice; the fee comparison covers its terms.
Who OAPP suits
OAPP fits people whose condition isn't on the 58-condition list but who are, or could be, prescribed an opioid for it. Pain after surgery or an injury is the obvious example. It also fits someone who wants a short trial before committing to a multi-year registration.
It doesn't fit anyone under 21, and it doesn't fit someone whose practitioner is an APRN or PA, since only physicians may certify OAPP patients. If chronic pain is your diagnosis, it's on the regular list too; see our chronic pain guide for that route.
Need the certification first?
IDPH won't open your application until an Illinois practitioner certifies you. Book an online evaluation with a licensed practitioner; code DRWDY85872 takes 5% off. The practitioner, not the booking site, decides whether you qualify.
Book an Illinois evaluation →Veterans
Since September 30, 2019, veterans who receive VA care and have a current opioid prescription have been eligible for OAPP. Veterans also have the reduced fee and a VA records route on the regular program, covered on the veterans page.
Renewing every 90 days
IDPH's OAPP page describes the registration as renewable, with the window opening 30 days before it expires. The general renewal page, though, lists opioid registrations among the types it doesn't handle, so follow the OAPP-specific instructions. If anything is unclear, email [email protected] or call 1-855-636-3688 (Monday to Friday, 9 a.m. to 4 p.m.). The regular program's cycle is explained on the renewal page for comparison.
Getting started
You'll need a physician licensed in Illinois who will certify you for OAPP specifically; ask before you book, because not every certifying practitioner is a physician. The certification page explains who can certify for each program and where things stand on remote exams. From there, the application runs through the same IDPH system and ILogin account described in the application guide.
