What's new?

The Illinois Department of Public Health's Division of Medical Cannabis added the feature to the patient registry, Illinois News Joint reported on Oct. 26. Now the registry shows each recorded purchase and how much it took off your limit. The state posted desktop and mobile user guides and a 12-page FAQ, all dated Oct. 29, 2026.

How do I find it?

The state's guides list three steps:

1. Log in to your Medical Cannabis Patient Registry account (the state uses its ILogin sign-in).
2. Scroll to the bottom of your patient dashboard.
3. Click "Available Allotment & Purchase History."

It works in a phone or computer web browser. If the login fails, the FAQ says to use the email you use with other State of Illinois programs. Logins from the registry's old system no longer work, so you may need to register again with the email you had there.

What does the purchase history show?

Each row has five columns, the FAQ says:

• Date: the date and time of checkout
• Dispensary: the store's official licensed business name, which may differ from the name on its sign
• Item: the product name, which should match the package label
• Quantity: how many of that item were recorded
• Ounces used: how much the purchase took off your allotment

It doesn't show prices. For those, the FAQ says to ask the dispensary, giving your patient number and the date and time of the sale.

How do purchases count against my limit?

Most medical patients have a 2.5-ounce allotment, or 70.87 grams, over any 14-day period, the FAQ says. Patients may apply for a waiver of up to 10 ounces. Only the health care provider who certified you can request a change, and IDPH reviews it. Purchases older than 14 days still appear in the 30-day history but no longer count against your limit.

Products count differently. The FAQ converts each one to the dried flower it stands for:

• Flower counts its own weight. An eighth (3.5 grams) takes off 3.5 grams.
• Edibles and drinks count total THC in grams times 3.33. A 100-milligram package takes off 0.333 grams.
• Concentrates such as vape cartridges count times 2.66. The FAQ's example: a 1-gram cartridge takes off 2.66 grams.

One FAQ answer describes the concentrate multiplier as applying to total THC and another as applying to product weight. The state's worked example matches weight. If your numbers don't line up, ask your dispensary.

The system calculates to three decimal places but shows two, and it rounds your remaining allotment down. A balance of 2.499 shows as 2.49, the FAQ says, so a dispensary may be able to sell you slightly more than the screen shows without going over.

Why is a purchase missing or wrong?

Dispensaries have to report each sale to the state, and the FAQ says there can be delays before it shows up. It lists other common causes:

• The purchase was more than 30 days ago.
• It was made under an old patient number. The history shows only your current number.
• The dispensary typed the wrong patient number or recorded the sale as adult-use.
• You shop at a store that isn't licensed for medical sales. Not all are.

The state says to start with the dispensary. Dispensaries can correct errors, but their audit rules require documentation, so fixes can take time. Report a dispensary that doesn't appear at all to both the store and the state's Cannabis Regulation Oversight Office at FPR.CROO@Illinois.gov.

What can caregivers see?

Caregivers see the same allotment and history as their patient. That includes every purchase made on the patient's number by any authorized caregiver, the FAQ says, without showing which caregiver made it. If you're both a patient and a caregiver, you pick which dashboard to view, and the two histories stay separate.

Who else can see my purchases?

According to the FAQ, the history is available only to you and your registered caregivers. Each dispensary sees its own sales receipts, including patient numbers, but not purchases at other stores. Medical dispensaries can look up your available allotment by patient number. The history pulls the last 30 days each time you open it and isn't stored in the registry. Don't share your login. You may share the history itself with whoever you choose.

Who do I contact?

• Questions about a specific purchase: the dispensary
• Login, waiver or account problems: IDPH at DPH.MedicalCannabis@illinois.gov or 855-636-3688
• Feedback about the system, or a missing dispensary: IDPH or FPR.CROO@Illinois.gov
