Overview Of What's Needed

Step 1: Submit Application / Purchase ID Card

You must have a valid, accessible email account. Complete and submit the online application form on the MMCC Registry website.

Note: You will need to pay a $50 charge for a Medical Cannabis ID card, which will be valid for 3 years.

Step 2: Obtain Certification

Medical cannabis cannot be purchased without a valid written certification from a provider registered with the MMCC. Certifications are valid for a maximum of one year. To obtain your certification, you will take your MMCC patient ID number and medical information to a registered physician. The physician will provide you with a written certification.

Please note: If you do not purchase medical cannabis within 120 days of issue, the certification expires and you will need to obtain a new certification from your provider.

Step 3: Visit Dispensary

After your registration has been approved by MMCC and your provider has issued you a valid written certification, you are ready to visit a licensed Maryland dispensary to purchase medical cannabis.

An electronic copy of a clear, recent photograph. We strongly recommend using a free, highly-rated passport photo app widely available for download via the App Store, Google Play Store or anywhere apps are available.

Generally, the photo should look like a driver’s license or passport photo. Specifically, it must be a clear, color photo of the patient’s unobscured face taken within the last six months to reflect the patient’s current appearance and feature a plain white or off-white background. The patient must be clothed, directly facing the camera with both eyes open and should have either a neutral facial expression or a natural smile. The patient must not be wearing a hat, head covering, sunglasses or dark glasses.

The file must be an image file (.jpg) no larger than 3 MB in size and may not be digitally enhanced or altered in a way that changes the patient’s appearance.

If your photo does not meet the stated guidelines, your application will be returned.

For more examples of acceptable and unacceptable photos, visit the Passport Photos page of the US Department of State website. NOTE: Please do not use the photo cropping tool on the Passport Photos page; simply view the photos provided as samples of what is and is not acceptable.

Patients in hospice care may elect to submit a letter from the attending hospice physician in lieu of a recent photo. The letter must be from the Attending of Hospice Record (AOHR) physician on hospice letterhead stating that the patient is a hospice patient under his or her care. It may be uploaded in either .jpg or .pdf format.

  1. Complete and submit an online application. Visit the MMCC Registry website​and click Create Account under the Patients heading.
  2. Verify your email address. As soon as you have completed and submitted an online application form, a verification email will be sent to the email address you provided on your application. You mustclick the verification link in the email message to verify your email account. Without performing this step, your application is not complete and will not be reviewed by the Commission.

Completed applications will be reviewed by MMCC and you will receive a follow up email advising whether or not your application has been approved. Please retain the approval email for your records. It contains your Username, which you will need to log in to the Patient Registry, as well as your MMCC Patient ID Number, which your physician will need to issue your written certification for medical cannabis. Once you have a written certification, you will also need to provide your Patient ID Number when visiting a licensed dispensary to purchase medical cannabis.

  1. OPTIONAL: Designate a Caregiver. Once your application has been approved, you can log into the Patient Registry to access your account and designate a caregiver (on the Add/Remove Caregiver tab). Please note that the caregiver must be registered (submitted an application and received MMCC approval) prior to being designated.

Next Steps

After receiving MMCC approval, you are ready to visit a provider registered with MMCC to obtain a valid certification. Once fully registered and in possession of a valid certification, you will be able to print your temporary MMCC patient ID card, this will be required to purchase medical cannabis from a licensed Maryland dispensary.​

Please be sure to have your MMCC Patient ID Number with you when you visit your provider and the dispensary.​​​​
