Becoming a Patient as a Minor:

If you are under the age of 18, you can still become a patient, but a parent or legal guardian must agree to act as a caregiver, and they will be responsible for the control of your use; from obtaining cannabis on your behalf, to administering dosages. There is a separate application form specifically for minor-patients.
