Currently, card issuance by the DOH is around 21 to 28 days, with some taking longer. We DO NOT know the status of cards with the DOH. You can check your application status and follow its progress online at your own Dept of Health MEDMJ account. 

(if you need your card ASAP, feel free to come in during any card hours, after prescreening) 

How to get a marijuana card in Hawaii? The quick overview!

  1. All new patients should Pre-Office screen.  ( To get contact information, sign up above. Filling out the above Contact Information fields and submittting them to me is NOT prescreening. 
  2. Patients complete the Dept. of Health online registration process before being seen in the office( Please fill out the DOH online registration carefully as there are way too many errors being made, and the system does not allow us to edit any patient application. See the above link for the common errors. The State DOH expects perfection! These registrations bounce from your queue to my queue once submitted. 
  3. Patients must be seen in the clinic and visit with Dr Barton to complete the DOH registration certification( The DOH application registration is sent to the DOH queue for state processing once certified. Clinic hours and fees: We do NOT use a traditional appointment system.
  4. The state will mail your card directly to you in about 3 to 4 weeks.
  5. My Name on state forms is David Barton


Summer is over, so the need for the Thursday Office Clinic is over. The card hours for Oahu will be Wednesday afternoon and Saturdy morning only.

Please remember, you are not legal until your DOH online registration has been certified by the doctor, after your clinic evaluation.

In view of the numerous incomplete and error filled online registrations needing fixing, make sure to check the status of your DOH registration to make sure it has been submitted to the DOH after your clinic visit. Once submitted to the DOH, all unfixed errors will be addressed by the DOH through your email contact information.

I would also like to post a warning to patients about so called "vet support" groups, who have formed just to sell vets cannabis. Although they may have a sincere interest in helping vets, you should not have to pay any of them a fee to facilitate the issuance of a medical cannbais card! I have absolutely no business relationships with such groups.
