A marijuana industry group sent letters to seven governors in the Northeast on Thursday, imploring them to push for cannabis legalization to aid in economic recovery amid the coronavirus pandemic.

The National Association of Cannabis Businesses (NACB) said a regionally coordinated legalization strategy would help generate much-needed tax revenue from legal marijuana sales.

“Governors in the northeastern U.S. have been working tirelessly and effectively to contain the coronavirus crisis, and the NACB has great respect for their efforts,” Mark Gorman, NACB executive vice president, said in a press release. “We are also enthusiastic for their leadership of efforts to coordinate the resources and strategies needed to emerge from the lockdown.”

NACB members from the marijuana and hemp industries include Hoban Law Group, SheppardMullin, CohnReznick, Cannabis Talk 101, Rise Recruitment, Mabre, CannabisConnect The Hemp Mine, EmeraldMetrics and Green Star Growing, according to the group’s website.
