Registration renewal

Cardholders must renew registration every year. When it is time to renew, we will send a renewal packet including:

  • Renewal instructions
  • An application form that shows your current registration information
  • An Attending Physician's Statement
  • Current registration expiration date
To renew your registration, submit:
  • Application form - Review and return the application form you received with your renewal packet. Check that all information is correct, including caregiver and grower/grow site (if applicable). If you need to make changes, mark them on the form. Changes will not apply to your current registration. To make a change to your current registration, see above for making changes.
  • Copies of valid photo ID (pdf) for patient and designated caregiver and grower. See samples of valid ID.
  • Completed Attending Physician's Statement Disabled veterans who meet the qualifications per 333-008-0040 (2)(a) or (b) do not have to submit an Attending Physician Statement annually to the program.  Please see Frequently Asked Questions page for qualifications.
  • Fee payment. Note: Effective 4/1/2016, the grower fee is $200.
  • If you are registering a minor, submit the Declaration of Person Responsible for a Minor to Participate in Oregon Medical Marijuana Program with the renewal application

Do not submit your renewal application too early. An Attending Physician Statement must be signed within 90 days of your current registration expiration date. If you send your renewal application more than 90 days before your current card expires, your Attending Physician's Statement will not be valid.

If the OMMP does not receive your complete renewal application by the current registration expiration date, your registration card will no longer be valid and you will no longer be protected from civil and criminal penalties.


A patient may request the expiration of his/her cards be extended if he/she is facing a personal hardship.

To request an extension:

Submit the Extension Request form before your current registration expiration date.

In order for an extension to be granted, the extension request must be:

  • Received on or before the date the cards expire
  • Signed by the patient
  • The only extension request granted to the patient in the last 3 years

Withdrawing from the program

A cardholder may withdraw from OMMP at any time by submitting a signed request.

  • All cards must be returned to the OMMP within 7 calendar days of the date that the OMMP was notified of the withdrawal.
  • It is the responsibility of the patient to notify his/her caregiver and/or grower that his/her card is no longer valid.
