If you are under the age of 18, a physician can certify that you have a qualifying medical condition requiring a medical cannabis card, however, those under 18 do require a designated caregiver to be approved. Your physician certifications and designated caregiver application must be turned in at the same time. The first caregiver application is free of charge, but any additional caregivers will incur an additional cost. In addition, minors can only use cannabis-infused products and are not permitted to purchase smokeable products.
