Two lawsuits have been filed in federal court seeking to overturn Massachusetts’ four-month ban on the sale of vaping products.

Gov. Charlie Baker last week announced a temporary ban on the sale of all vaping products — whether containing nicotine or THC — in light of a nationwide outbreak of severe, vaping-related lung illnesses. The ban was approved by the state’s Public Health Council.

Mass Dynamics, Boston Vapor and Vick’s Vape Shop filed a lawsuit on Sunday against Gov. Charlie Baker and Public Health Commissioner Monica Bharel in U.S. District Court in Boston. Mass Dynamics is based in Weymouth; Boston Vapor is based in New Hampshire and has Massachusetts stores; and Vick’s Vape Shop is in Medford.

The lawsuit argues that federal law preempts Baker’s ban because the U.S. Food and Drug Administration already regulates e-cigarettes and other vaping products.

By implementing the ban, plaintiff’s attorney Craig Rourke wrote in the complaint, “the Commonwealth placed itself squarely in opposition to the FDA’s expert determination that the Plaintiffs’ products were approved and regulated under federal law.”

The shops are arguing that Baker’s ban impedes interstate commerce and infringes on their constitutional rights by preempting federal regulations.

They say the court needs to act, both to protect their rights as businesses and to protect consumers who “will be forced to return to smoking cigarettes or obtain unregulated [electronic nicotine delivery systems] products and e-liquids by other means.”

Another lawsuit was filed in federal court on Tuesday by the Vapor Technology Association and additional businesses. That lawsuit argues similarly that Baker is impeding interstate commerce and also infringing on businesses’ First Amendment rights by banning the display of vape products.

That lawsuit argues that the ban “has shuttered and will irreparably destroy Massachusetts’ $331 million nicotine-vapor-products industry, and the livelihoods of the 2,500 workers that it employs.”

The Vapor Technology Association lawsuit argues that the ban “makes no distinction between the black-market vaping products at the center of that outbreak, and the FDA-regulated products produced by legitimate manufacturers.”

A separate lawsuit by the company Vapor Zone has been filed in state court.
