Authorized representatives of state or local law enforcement agencies (e.g.; police, sheriffs, district attorneys, state troopers, marijuana enforcement division representatives) may request verification of an individual’s registry card or application.


How to submit a verification request:

The law enforcement representative shall submit to the Registry's Fraud Prevention Unit a written request on agency letterhead by mail, hand delivery or fax to 303-758-5179. Verification requests by phone or email are not accepted. The request must include:

  • A statement to the effect that they were presented with a registration card or complete application packet by an individual whose name appears on the documentation OR that the person in question was contacted by law enforcement and claimed to be a patient/primary caregiver on the Registry, but was not in possession of their registration card/application packet;

  • The name on the registration card; and

  • The registration card number.


Supporting documentation required for the following reasons: 
  • Application packet used as proof of registration: If a complete application packet is presented to law enforcement, a copy must accompany the request for verification. A complete application packet includes an application, the physician’s certification, and a certified mail receipt or other proof of mailing to the Registry.
  • Patient information is submitted to law enforcement by an attorney representing the patient or caregiver: If the law enforcement officer or district attorney received the card or paperwork from an attorney representing the patient or caregiver, the representing attorney must also provide proof of their legal relationship to the patient or caregiver. This may include a court pleadings subpoena or a letter of representation on the attorney’s letterhead with a signed, notarized waiver from the client. This documentation must be provided to the Registry along with the verification request.
The Registry’s response to verification requests:
We will provide a written response that includes the following information:
  • Confirmation of the patient’s status;
  • Date the application was received or the registration card was issued;
  • The date the card expired or will expire; and
  • The name of the person to whom the card was issued.



Policy Number 2012-07 provides procedures, costs and contact information for submission of subpoenas.

Authorized employees of state or local law enforcement agencies shall immediately notify the Medical Marijuana Registry when any person in possession of a Medical Marijuana Registry identification card has been determined by a court of law to have willfully violated the Colorado Constitution or the referenced statutes, or has pled guilty to such offense.

Notices may come in the form of:
a. Notice of Conviction, Court Finding, or Final Disposition related to a court conviction, or
b. Law enforcement Summons or Citation with a signed admission of guilt in lieu of a court appearance.
Notice must be received in writing by fax (303-758-5179) or mail to:
