Four Terrabis Dispensaries in Illinois Begin Serving Medical Patients

Terrabis began serving registered medical cannabis patients on September 21, 2026, at four of its five Illinois dispensaries: Woodstock, Dixon, Plainfield and Grayville. The company’s Mundelein location will join the medical program pending local approvals, the company said in an announcement.

Registered patients shopping at the participating dispensaries will receive priority service, help navigating the Illinois medical cannabis card process through a step-by-step guide on the company’s website and virtual consultations with licensed physicians through Leafwell, and a penny pre-roll or gummies with a first purchase for new medical patients, according to the announcement.

The expansion follows new Illinois rules allowing more adult-use dispensaries to serve registered patients. Governor JB Pritzker signed SB 3222, now Public Act 104-0463, on June 12, 2026, amending the Cannabis Regulation and Tax Act and the Compassionate Use of Medical Cannabis Program Act, according to a fact sheet from the Illinois Department of Financial and Professional Regulation. Most provisions took effect immediately upon signing, but the change authorizing licensed dispensaries to opt in for a medical dispensary license became available starting September 10, 2026, as a rolling application process rather than a limited window.

On that date, Pritzker and the department issued medical cannabis dispensary licenses to 37 existing dispensaries, which may serve both adult-use customers and medical patients at the same location, according to a department news release. Under the new law, an adult-use dispensary holding an active license in good standing may apply for a medical cannabis dispensary license, and once approved may sell cannabis to registered patients at the medical tax rate, up to the patient’s authorized allotment. The law also prevents dispensaries from separating an adult-use license from its medical license, either in the facility itself or in the ownership, and all cannabis products sold to medical patients must carry a federally mandated warning label applied before the sale. The department said the change also lets newer dispensaries issued under social equity lotteries serve medical patients.

“Expanding access to medical cannabis is an important step toward ensuring Illinois patients have more options to obtain the medicine they rely on,” said Mario Treto Jr., the department’s secretary. More dispensaries mean better options and increased convenience for medical patients while maintaining the regulatory safeguards that protect patients, he said.

Drive-Thrus, Hours and a 35-Mile Gap

Each Terrabis location is set up to remove a different barrier patients face depending on where they live, the company said. In Woodstock and Grayville, patients can use drive-thru service. Grayville opened what the company describes as the state’s first dual-window dispensary drive-thru earlier in September 2026, and Woodstock opened McHenry County’s first.

In Dixon, the nearest medical dispensaries had been 35 miles or more away, and the company said patients in Lee County and the surrounding area can now meet their needs locally. The Dixon City Council amended its local cannabis ordinance in September 2026 to permit drive-thru service, and Terrabis is working with the city and the state on plans for a drive-thru window.

The Plainfield dispensary operates from 6 a.m. to 2 a.m. Tuesday through Saturday, hours the company said extend well past most dispensaries in the area. A drive-thru is planned there as well, pending local and state approvals, and the company said it intends to bring drive-thru service to all five of its Illinois dispensaries as approvals allow.

SB 3222 permits dispensaries to offer drive-through windows and curbside pickup once their systems have been reviewed and approved by the department, a process that begins with a request including an updated floor plan, an updated security plan and standard operating procedures, according to the fact sheet. The law also allows dispensaries to expand their hours of operation to 2 a.m. with local municipal approval.

Two-Week Patient Drive With Leafwell

Terrabis has worked with Leafwell since its Missouri days and carried the partnership into Illinois, offering discounted certifications and periodic patient drives, the company said. Beginning September 21, 2026, Terrabis and Leafwell are hosting a two-week online patient drive offering 30% off new medical card registrations and renewals, bringing the cost to $69. A standard discount will remain available through Leafwell after the drive ends.

CEO Dan Ambrosino said a patient who cannot afford the certification or cannot find a nearby provider is not in the program regardless of what the law says, and that lowering that first barrier is the most direct thing the company can do for the medical community.

Terrabis entered the cannabis industry as a medical operator in Missouri in 2021, serving registered patients before adult-use sales existed in that state, and it continues to operate four Missouri dispensaries. The privately held multi-state operator has a corporate office in Chicago, dispensaries in Illinois and Missouri, and a product manufacturing facility in Kansas City, Missouri.

“We built this company serving medical patients, and that has never stopped being the core of what we do,” Ambrosino said. Bringing medical service to four more Illinois communities means more patients can get that support and tax savings without a long drive, he said.
