How the Illinois list works
Illinois qualifies patients for medical cannabis by diagnosis. The Illinois Department of Public Health keeps a list of 58 debilitating conditions, last updated August 14, 2026, and the Compassionate Use of Medical Cannabis Program Act adds terminal illness with a prognosis of six months or less. A registered practitioner has to confirm you have one of them. There is no open-ended "any condition the doctor thinks appropriate" clause.
The grouping below is ours, to make the list scannable. IDPH publishes the conditions as one ungrouped list, and the wording in the right-hand column follows IDPH's.
The full list, grouped
| Group | Conditions on the IDPH list |

| Statutory category | Terminal illness with a diagnosis of 6 months or less (in the Act, not on the IDPH list page) |
Wording that changes who qualifies
A few entries carry qualifiers that do real work, and they're easy to skim past.
- Severe fibromyalgia, not fibromyalgia in general. The practitioner has to judge severity.
- CRPS is listed as Type II specifically. Reflex sympathetic dystrophy appears as its own entry.
- Spinal cord injury is defined as damage to the nervous tissue of the spinal cord with objective neurological indication of intractable spasticity.
- PMOS qualifies when it comes with chronic pain.
- Seizures are listed broadly, "including those characteristic of epilepsy."
Chronic pain is the broadest entry on the list, and the most used. In IDPH's FY24 annual report it made up 36.39% of the condition breakdown, ahead of PTSD (15.54%), migraines (10.24%), osteoarthritis (7.92%) and cancer (4.72%). Our guides on chronic pain and the Illinois card, PTSD certification and migraines cover those three.
Recent additions
The women's-health group appears to be the newest part of the list. The current IDPH page includes endometriosis, ovarian cysts, uterine fibroids, female orgasmic disorder, PMOS with chronic pain and sickle cell disease. We couldn't confirm the exact date each was added from an official source, so if you were turned away for one of these in the past, it's worth asking again. The endometriosis and women's health guide covers that group, and the arthritis guide covers the two arthritis entries.
Common conditions that aren't on it
Anxiety, depression and insomnia don't appear on the list. That's a firm no for the condition by itself, though some people with those symptoms also have a listed diagnosis such as PTSD or chronic pain. Our anxiety and the Illinois list post goes through it honestly. If you don't qualify, adult-use purchase at 21 is still legal in Illinois.
Next step
If your condition is on the list, the next move is a certification from an Illinois practitioner registered with IDPH. Bring records that document the diagnosis. The application walkthrough covers the rest, and the full set of condition guides covers the other entries.
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.

Is anxiety a qualifying condition in Illinois?
No. Anxiety is not on the IDPH list. PTSD is, and so are several conditions that often come with anxiety symptoms. A practitioner can only certify a listed condition.
Does Illinois have an 'other conditions' category?
No. The only addition outside the IDPH list is the statutory category of terminal illness with a diagnosis of six months or less.
What was the most common qualifying condition?
Chronic pain. In IDPH's FY24 condition breakdown it was 36.39%, followed by PTSD at 15.54% and migraines at 10.24%.
Who decides whether my condition counts?
The certifying practitioner. They must be an Illinois-licensed physician, APRN or physician assistant registered with IDPH, and they decide whether your diagnosis matches a listed condition.
