7 things to know about Illinois's medical marijuana program
Illinois runs its medical cannabis program through the Department of Public Health. A licensed health care provider certifies that the patient has one of the state's listed debilitating conditions, and the exam can be done by telemedicine. The patient then applies through the IDPH online portal using a State of Illinois iLogin account, links the provider's certification and pays a fee of $50 for one year, $100 for two or $125 for three. Veterans and SSI or SSDI recipients pay half. Although adult-use cannabis is also legal, registered patients pay far lower taxes, can buy more, and can grow up to five plants at home.
