About Us

The Medical Marijuana Registry is a confidential, statewide program that allows patients with qualifying, debilitating medical conditions to receive a registry identification card for legal access to medical marijuana. Cards are available to Colorado residents and valid only in Colorado. 

We only issue registry identification cards and maintain the database of registered patients. For questions about medical marijuana centers or caregiver cultivation sites please visit the Marijuana Enforcement Division at the Department of Revenue for more information.
