It depends. Registration is voluntary for adult patients (age 18 and older); however, unregistered patients will not receive registration benefits, such as tax exemptions.
Patients aged 18 to 20 must register and have a recognition card to purchase products from a medically-endorsed store. These patients may not purchase cannabis from a store without a medical endorsement.
Registration is required for minor patients (under age 18) and their designated provider (parent/legal guardian).
