MARION, Ill. — A southern Illinois doctor who works at a clinic where many patients try to access the state’s medical marijuana program has been subpoenaed in a state and federal investigation.

State officials told the Southern Illinoisan ( ) that the investigation is in response to alleged improper controlled substance prescriptions from Dr. Bodo Schneider.

Illinois Department of Professional and Financial Regulation spokesman Terry Horstman said the terms of the subpoena require Schneider to provide medical records to the state regulatory agency by Oct. 7.

Horstman said an administrative law judge was informed of the subpoena during the most recent status hearing in the case involving Schneider on Sept. 16. The administrative law judge was also told that Schneider rejected an offer by the department’s State Medical Licensing Board at an informal meeting Aug. 19.

Another status hearing in the case is scheduled for Oct. 24.

Schneider is the medical director of clinics in Marion in southern Illinois and Orland Park in suburban Chicago. He is one of only a few doctors in southern Illinois participating in the state’s medical marijuana program by certifying the conditions of qualified patients.

Illinois regulators say Schneider charged patients for marijuana recommendations at his offices without a legitimate doctor-patient relationship. The state says the acts he’s accused of are grounds for suspending or revoking his Illinois medical license.

Schneider has said he has followed all of the state’s rules for the medical marijuana program.

Doctors don’t prescribe medical marijuana, but they sign off on whether an individual has one of the conditions the Illinois law allows for eligibility to receive an identification card to be used at a dispensary.

People wanting access to the program have flooded Schneider’s office as the region’s major health systems have told their physicians not to participate, citing legal vulnerability since marijuana, including medical cannabis, is still illegal at the federal level.
