Illinois’ medical cannabis program is generating a fraction of the tax revenue it once did, raising questions about whether the state is doing enough to make cannabis affordable and accessible to registered patients. While the adult use market has expanded across the state, access to medical cannabis and its associated tax benefits remains a concern, particularly for patients who lack reliable transportation or live far from a qualifying medical dispensary.
According to the Illinois Department of Financial and Professional Regulation’s 2026 Annual Cannabis Report, revenue from medical cannabis sales tax has declined substantially since fiscal year 2021. That year, Illinois collected approximately $6.3 million in medical cannabis sales tax revenue. By fiscal year 2026, that figure had fallen to $2.5 million.
Meanwhile, adult use cannabis continues to generate substantially more tax revenue. In fiscal year 2026, Illinois collected approximately $188.6 million in adult use sales tax revenue and $223.8 million through the Cannabis Purchaser Excise Tax. Total dispensary state tax revenue reached approximately $422.6 million.
The difference highlights how much state cannabis revenue now comes from the adult use market compared with the medical program. However, declining medical cannabis tax revenue alone does not establish that patient numbers or medical cannabis consumption have fallen by the same amount. Tax revenue and retail sales are different measures, and the figures cover different reporting periods.
Illinois originally licensed 55 medical cannabis dispensaries, compared with approximately 288 adult use dispensary locations. Based on those figures, adult use locations outnumber the original medical dispensary network by more than five to one.
That imbalance matters because medical cannabis patients should not have to pay more simply because they cannot conveniently reach a location authorized to serve them as medical customers.
There has been progress toward expanding access. In June 2026, Governor JB Pritzker signed Senate Bill 3222, which allows adult use dispensaries to register as medical cannabis dispensaries. On September 10, the state announced that 37 existing adult use dispensaries had received medical licenses, allowing them to serve both adult use customers and registered medical patients at the same location. The law creates an opportunity for additional adult use dispensaries to seek medical licenses as well.
Under the new licensing framework, registered medical cannabis patients can purchase cannabis at the medical tax rate from participating dispensaries that have received the required medical authorization, up to their authorized allotment. This is an important step toward reducing barriers to medical access.
However, expanding the number of qualifying dispensaries does not automatically eliminate geographic barriers. Patients still need a conveniently located dispensary that is authorized to serve them as medical customers. Those who cannot reach one may have to shop at an adult use only location, where they do not receive the same medical tax treatment.
For patients who depend on cannabis for medical purposes, this can create an unnecessary financial burden. People living on fixed incomes or managing other healthcare expenses may already struggle to afford the products they rely on. Their ability to save money should not depend on whether they can drive to another community, arrange a ride or travel a significant distance to reach a qualifying dispensary.
The latest medical cannabis sales figures show that the program continues to serve a substantial market. According to the Illinois Department of Public Health’s Medical Cannabis Patient Program reporting, monthly medical cannabis retail sales reached $12,759,858.42 in September 2026, based on the figures provided. That included $6,439,200.19 in dry flower sales and $6,320,658.23 in concentrates and infused products.
Monthly medical cannabis sales remained relatively consistent throughout the first nine months of 2026, generally ranging from approximately $12.5 million to $13.6 million. January sales totaled $13,363,063.05. May recorded the highest monthly total in the figures provided, at $13,571,646.50. September sales totaled $12,759,858.42.
These monthly sales figures demonstrate that medical cannabis continues to represent a meaningful market in Illinois, even as the state’s reported medical cannabis sales tax revenue has declined. They should not be directly compared as though they measure the same thing. Retail sales represent the value of products purchased, while tax revenue reflects money collected under the applicable tax structure. The fiscal year figures also cover a different period from the calendar year sales totals.
The question is not whether Illinois should continue expanding its adult use market. It is whether the state can support that market while ensuring registered medical cannabis patients retain meaningful financial advantages and practical access to the products they need.
Illinois should prioritize expanding medical purchasing options in communities where patients lack convenient access to a qualifying dispensary. The state should also evaluate how its licensing framework, patient verification process and tax policies affect people who depend on medical cannabis but cannot easily travel to a participating location.
The expansion authorized by Senate Bill 3222 is a positive step, but access must be measured by more than the number of licenses issued. Patients need nearby locations where their medical registration is recognized and the appropriate tax rate is applied without unnecessary confusion or barriers. Clear information about participating dispensaries would help patients understand where they can shop and receive their medical tax benefits.

Affordability is especially important for patients who purchase cannabis regularly. Even modest tax differences can add up over weeks and months, placing additional pressure on household budgets. A medical cannabis program that exists on paper but remains difficult or expensive to access does not fully serve the people it was created to help.
Illinois has established a major adult use cannabis market that generates hundreds of millions of dollars in state tax revenue. That success should not come at the expense of patients who rely on cannabis for medical purposes. The state has an opportunity to strengthen its medical program by making qualifying dispensaries more accessible and ensuring registered patients can receive the tax benefits associated with their status.
Medical cannabis access should be about patients, not just market expansion. If Illinois wants its medical program to remain meaningful, it must make cannabis more affordable and accessible regardless of a patient’s ZIP code, transportation options or proximity to a qualifying medical dispensary.
