Hawaii medical marijuana FAQ: answers from the official program
Answers to the questions Hawaii patients ask most, based on the Hawaii Medical Cannabis Registry Program's own guidance.
Can I get certified for medical cannabis in Hawaii by telehealth?
Yes. The Department of Health says your provider relationship can be set up through an in-person or a telehealth visit. The provider must still have a genuine treating relationship with you.
How much does a Hawaii 329 card cost?
The state application fee is $38.50 for in-state patients. Changes to an existing registration cost $16.50.
I'm visiting Hawaii — can I use my medical card from home?
You need to register as an out-of-state patient online and pay $49.50. The card lasts up to 60 days or until your home card expires, and you can apply twice per year.
Can I grow cannabis at home in Hawaii?
Yes. Registered patients may grow up to 10 plants at the grow site listed on their card. A registered caregiver may also grow for the patient.
How much can I buy at a dispensary?
Patients can buy up to 4 ounces in any 15-day period and up to 8 ounces in any 30-day period. Total possession is capped at 4 ounces of usable cannabis.
