Colorado Medical Marijuana Registry Home Page

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.

The Department hosted a Town Hall Meeting  on March 28 at the state Capitol. The purpose of the meeting was to introduce proposed legislation to address Office of the State Auditor’s recommendations regarding contractors and caregiver limits, introduce a new department policy on the review of medical necessity, and provide the opportunity for public comment to the proposed legislation as well as the department's new policy on medical necessity review.  A copy of the draft Legislative Audit Committee bill presented at the meeting and a summary of public comments are available for review. A letter was sent on April 1, 2014 to inform all physicians active on the Registry  about the change in Department procedures. Please send feedback to physicianreview@state.co.us.
Effective February 1, 2014, the application fee is $15 . 
The Board of Health approved the Department's recommendation for a reduced fee at the December 18, 2013 meeting. Meeting minutes and details of the proposal are available on their website.
