Frequently asked questions How do I become a Caregiver in Georgia? If you are in need of a medical cannabis card for a minor or are an adult’s legal caregiver/guardian, you may qualify for a Georgia Low THC Registry Card and access cannabis on their behalf. The process of becoming a Caregiver in Georgia is similar to theprocess for a patient, except the caregiver must be aged 21 or over. This means that the caregiver will also need to provide the physician and the Ministry of Health of Georgia proof of identity and residency, and will need to pick up both their own and the patient’s card. This also costs $25.
