In Missouri, patients are allowed to designate caregivers to grow or purchase, transport and help administer their marijuana. The caregiver must have this Patient Authorization Form filled out by the patient they’re going to care for. The caregiver will then complete their online application via the registry portal and pay the $26/50 application fee. If the caregiver is planning to cultivate for the patient, there’s an additional $53 fee and a separate additional application.
