A trade group that represents New York medical marijuana growers in a lawsuit against the state has changed law firms.

The New York Medical Cannabis Industry Association, which represents the top five companies awarded a license to grow and dispense medical marijuana in July 2015, had retained national law firm Harris Beach when it filed a lawsuit against the state in Albany County Supreme Court in May, New York Medical Cannabis Industry Association v. NYS Dept of Health, 2848-17.1, seeking to stop the state’s Department of Health from awarding licenses to five more companies. The association claims that growing the operations would cannibalize the medical marijuana industry, which is struggling in New York.
