Maui Grown Therapies, which has a medical marijuana dispensary in Maui Lani, on Tuesday received a historic go-ahead to begin selling its products.

The Health Department issued a formal notice to proceed to Maui Grown Therapies after the dispensary completed laboratory testing and passed its final onsite inspection Monday.

It is the first of eight dispensaries in the state to receive the go-ahead to begin selling medical cannabis products.

“It’s been a long, winding road to get here and we’re extremely excited,” said Maui Grown Therapies co-founder Dr. Gregory Park. “Getting to this day required hard work, cooperation and patience, but it’s worth it to be able to bring this alternative therapy to our Maui community.”

He also thanked Maui County state Sen. Roz Baker and state Rep. Delia Bellati for their leadership and the Health Department “for establishing high compliance standards for this emerging industry.”

The first sale is expected to be made Tuesday morning at the dispensary in the Maui Lani Village Center, 44 Paa St., according to company spokeswoman Teri Freitas Gorman.

She said earlier this month that Maui Grown Therapies would begin selling flowers, capsules and oil concentrates and expand offerings later.

Maui Grown Therapies will ease into operations with a short “soft opening week” during which patients who have gone through pre-opening intake will be able to purchase by appointment. On Monday, walk-in business and regular operating hours –10 a.m. to 7 p.m. Monday to Saturday — will begin.

Maui Grown Therapies has registered nearly 300 patients through open houses since April, Freitas Gorman said earlier this month. There are almost 4,000 registered medical marijuana patients on Maui.

“This is an important day for qualified patients and caregivers on Maui who now have assurance the medical cannabis they purchase at Maui Grown Therapies has been thoroughly tested and is safe for them to use,” said Health Department Director Dr. Virginia Pressler. “Implementing a new health program is always challenging, and the dispensary program was no exception.

“With legal guidance from Department of the Attorney General, the DOH team paved the way for this new industry in Hawaii and has set a new standard for dispensary programs other states can emulate.”

The eight dispensaries statewide were awarded their licenses in May and were legally allowed to begin selling a year ago. However, the regulation and certification procedures needed to be established by the Health Department before sales could begin.

Registered patients and their caregivers may purchase up to 4 ounces of medical cannabis during a 15 consecutive day period and purchase a maximum of 8 ounces over a 30 consecutive day period, the Health Department said. All use of medical cannabis must be on private property and may not be used in a car while on the road, at work, at the beach, on hiking trails or in any other public space.

It is illegal to use or possess medical cannabis on any federally-owned property such as military installations and national parks. When bringing medical cannabis home after purchasing it from a dispensary, the medical cannabis must be in a sealed container and not visible to the public.
