About Us

Doctor420Hawaii provides medical cannabis & marijuana certifications for qualifying patients in Hawaii. We have assisted more than 4,000 patients to lawfully possess marijuana and cannabis products for medicinal use since 2003.

Doctor420Hawaii is a Medicinal Cannabis Evaluation Center providing 329 marjuana card certifications.

We are NOT an authorized retailer or distributor of medical cannabis or marijuana products. Please contact the state licensed dispensary nearest you to purchase marijuana.   We will accept out-of-state identification to obtain a 329 card as long as the patient can provide both a local physical AND mailing address.   Certifications take a minimum of four (4) weeks to process and must be renewed every year to stay current.   Please take a moment to review the 329 card eligibility requirements on our website before contacting us. 

Our office is located in Hilo on the Big Island, and we travel to O'ahu, Maui, Molokai, and Kauai to hold monthly clinics for our patients. Contact our office today to see if you are eligible for a 329 marijuana card and/or to become a caregiver.

Effective Change, LLC is a Hilo Medicinal Cannabis Evaluation Center


Island of Hawai’i residents searching for medicinal cannabis, also known as the 329 card, can contact Effective Change, LLC in Hilo for a certified medical marijuana evaluation. This medical cannabis evaluation center with a heart is physician-owned and physician-run and services all main Hawai’i islands.


A core, diverse team of four leads Effective Change in Hilo: Matthew Brittain, LCSW, Dr. Christopher Lawinski, M.D., as well as Jonelle and Tatiana. As a team, they bring to bear far-reaching expertise from the areas of general medicine, cannabis cultivation, human forensics, and mental health to provide patients with the most comprehensive and compassionate care possible. Effective Change prides themselves on their ethnic diversity: African, Caucasian, Filipino, Hawaiian, and Korean! They’ve got it all, and they love to share and support all things cannabis.


The good people at Effective Change in Hilo have faithfully served Hawai’i residents longer and more carefully than any other medicinal cannabis evaluation center in Hawai’i. Hilo patients, and others residing on the Big Island - curious or otherwise interested in the palliative potential of medicinal cannabis - can contact the warm and friendly team at Effective Change with any questions or concerns.



Effective Change has been around for nearly two decades. The team has advocated for cannabis since 1999 when a bill proposing legalization made its way into the legislature. To take things further, Matthew Brittain, Effective Change’s founder, became one of Hawai’i’s leading medical cannabis advocates since helping found the business in Hilo in 2002.


Effective Change took on the mantle of cannabis certification coordination in 2002 when one of the founding fathers of the Hawai’i cannabis program, Dr. Wenner, passed away. Effective Change stepped in to provide continuity of care to many of his patients. Effective Change has gradually expanded its services ever since, including O’ahu and Kaua’i in 2006, Moloka’i in 2007, and Maui in 2010.



The first step to acquiring a medicinal cannabis recommendation in Hawai’i is to contact a state-approved physician like Dr. Lawinski at Effective Change in Hilo. Once the doctor has certified the patient for medicinal marijuana use, Effective Change can then register the patient with Hawai’i’s Medical Marijuana Registry Program. Once this process is complete, Hawai’i’s Department of Health will issue the patient a 329 Registration Card which then grants the patient legal access to dispensaries statewide.


Local Legislation:

Out-of-state residents are unable to obtain medicinal cannabis recommendations because Hawai’i requires its patients to have state-issued identification, which one cannot receive without a permanent Hawai’i address. Medical marijuana legislation in Hawai’i also requires that prospective medical cannabis patients suffer from chronic, debilitating diseases in order to qualify for certification. For a closer look at Hawai’i’s qualifying conditions, check out the Department of Health’s website.


For those approved by the state to use medical marijuana, be mindful of its “adequate supply” laws as well as the prohibition of administration in public. The cannabis communities of Hilo, and elsewhere, should keep their eyes peeled for Senate Bill 548 which would legalize marijuana for recreational use islandwide.


Service Locations:

Islandwide. Effective Change now proudly serves every Hawaiian island excepting Lana’i. As the state’s sole islandwide medicinal cannabis certification center, no county or town is out of reach. From the populous Honolulu to the beautiful Haleiwa, if you’re on O’ahu, Effective Change has your back. From Kaawa to Nanakuli and Kapolei, the team at Effective Change will meet with you to help improve your happiness and wellbeing.


Location Information:


Hawai’i, a tropical paradise just a few thousand miles west of the westernmost coast of California, is home to some of the most sensational tropical vistas known to man. If you were to find yourself in Hilo on the Island of Hawai’i, be sure to trek through the Hawai’i Volcanoes National Park. Hikers, campers and beachgoers alike, the Big Island has something for everyone. From Mauna Kea Summit to Hapuna Beach, you can’t go wrong. Whether you’re trekking the Kilauea Iki Trail or letting the calm sands of Manini’owali Beach warm your toes, the Island of Hawai’i will never cease to amaze.
