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.cccc

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 Honolulu Medicinal Cannabis Evaluation Center


Hawai’i residents of the beautiful Honolulu now have access to the superb patient-first services of Effective Change’s certified medicinal cannabis evaluation center. Effective Change runs on compassion and heart. This physician-owned medicinal marijuana evaluation center covers every corner of Hawai’i, from Honolulu to Moloka’i and beyond.


A diverse team leads Effective Change’s Honolulu outreach from their offices in Hilo: Matthew Brittain, LCSW, Dr. Christopher Lawinski, M.D., as well as Jonelle and Tatiana. Collectively, their experience includes deep knowledge from general medicine, cannabis cultivation, human forensics, and mental health; this is what they draw from to provide patients with the most compassionate and comprehensive care possible. Effective Change also prides themselves on their ethnic diversity: Caucasian, Filipino, African, Hawaiian, and Korean! United by a singular vision, they love supporting and sharing all things cannabis.


Effective Change has served Hawai’i residents longer and with more care and compassion than any other medical cannabis evaluation center in Hawai’i. Honolulu patients, and others residing about Hawai’i should contact the welcoming team at Effective Change with any questions or concerns.



The team behind Effective Change has been advocating for cannabis since 1999 when a legalization bill appeared before Hawai’i’s legislature. Three years later, in 2002, Matthew Brittain founded Effective Change to push progress yet further.


Effective Change became a cannabis certification coordination center when one of the founding fathers of Hawai’i’s cannabis program, Dr. Wenner, passed away. They understood that his patients needed continuity of care, so they took up the mantle and continued to blaze the trail. Later, Effective Change would grow to expand its services: 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 Honolulu is to contact Dr. Lawinski at Effective Change. Once Dr. Lawinski has certified the patient for medicinal marijuana use, he or she must register with Hawai’i’s Medical Marijuana Registry Program — the very same program to which the Effective Change family belongs. Once finished with this process, Hawai’i’s Department of Health will send the patient a 329 Registration Card. With the 329 Registration Card in hand, the patient may then legally purchase medicinal cannabis treatments from 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 acquire without a permanent Hawai’i address. Medical marijuana legislation in Hawai’i also states that prospective medical cannabis patients must suffer from chronic ailments in order to qualify for certification. For a complete list of Hawai’i’s qualifying conditions, check out the Department of Health’s website.


For those okayed by the state for medical marijuana use, be mindful of its “adequate supply” laws as well as the prohibition of usage in public. The cannabis communities of Honolulu, and elsewhere, should keep eyes on Senate Bill 548, a bill which would legalize marijuana for recreational use statewide.


Service Locations:

Effective Change now proudly serves every main Hawaiian island. As the state’s only statewide medicinal cannabis certification center, no Hawaiian shore is too far. From Palolo to the beautiful Waikīkī, if you reside on O’ahu, the cannabis certification coordination experts at Effective Change can help. From Hawai’i Kai to Kailua and Kaneohe Bay, the compassionate hearts at Effective Change will meet with you to help you on your way to a happier, greener life..


Location Information:

Honolulu, O’ahu, the tropical gem of the Pacific Ocean, boasts some of the best and most diverse treks through natural wonders on this side of the world. Dive with the sharks off the Haleiwa coast, surf the westside waves in Waianae, or hike the trails of Koko Crater. History was made here; learn about Pearl Harbor from the USS Arizona Memorial or the Pearl Harbor monument in Honolulu. From the delicious sands of Waikiki to the wondrous schools of marine life in Hanauma Bay, Honolulu has something for everyone. Sportfishing, offroading in an ATV, hiking, lounging, or just flat out living life, the island of O’ahu cannot disappoint.
