Registered Qualifying Minor Patient 18 to 20 Years of Age Application Instructions

Minor Patient Registration Reapplication Instructions

** Important Notice: Minor Medical Cannabis Patients' cards are valid until they expire, regardless of the patient turning 18 years of age. **

Once the minor medical cannabis patient turns 18 years of age, they have two options:

  • If the patient would like an adult medical cannabis card, they can cancel their current card and apply again as an adult. Cancellation requests will have to email IDPH at In the email, include the patient's name, date of birth, caregiver name, caregiver date of birth, and the minor qualifying patient’s and the minor caregiver’s registration card numbers.
    Email Example for Cancellation Request:
    John Doe
    Jane Doe
  • Once the Minor Qualifying Patient’s card has expired and the patient is over 18 years of age, the patient (previous minor qualifying patient) can re-apply as an adult in the Illinois Cannabis Tracking System (ICTS). For Instructions, refer to the MCPP Patient Application instructions.
    Note: Before starting an MCPP Patient Application, contact your health care provider. Health care provider certifications are only valid for 90 days from the date of the in-person/telemedicine examination.

Parent of a disabled child who is unable to complete the application for themselves. Unlike with the pediatric application process, you cannot apply as a legal guardian for the patient. The application process must be done with all the patient information, and you will have to add yourself on as a caregiver.

Note: When re-applying as an adult patient, the application might auto-populate with the parent/guardian information instead of the patient’s information (double-check). Make sure you are using the actual patient’s name, otherwise the health care provider’s certification will not link.

Example A: Auto Populated Caregiver Information (Minor Caregiver Information)


Example B: Updated Application with Patient Information (Patient 18 to 20 years of age)
