Gov. Josh Green signed two bills Tuesday aimed at regulating tobacco use and electronic smoking devices in Hawaii.

Senate Bill 2175, now Act 189, prohibits the sale, offer for sale or distribution of disposable electronic smoking devices beginning Jan. 1, 2027. Violators may face fines of up to $100 per day for each violation.

House Bill 1573, now Act 190, strengthens oversight of electronic smoking devices and e-liquids sold in Hawaii by requiring manufacturers to certify that their products comply with federal and state law.

The measure requires manufacturers to provide documentation showing U.S. Food and Drug Administration authorization for their products. It also requires the state Department of the Attorney General to create and maintain a public directory of compliant products.

Manufacturers that fail to meet certification requirements, as well as entities that sell or offer products not included in the directory, will be subject to penalties.

“Hawaii has been a leader in this fight for years,” Green said in a news release. “It is more important than ever to preserve the health of our environment and ensure the health of our keiki. We have seen the effects and now we are taking action.”

State officials said disposable electronic smoking devices have created health and environmental concerns because they often contain single-use plastic and lithium batteries. The materials have been linked to landfill fires, litter, pollution and water contamination.

Lawmakers and advocates said the measures are also intended to reduce youth access to unauthorized and flavored vaping products.

“For years, the tobacco industry has used flavors, packaging and marketing tactics to attract young people to vaping products,” said Rep. Scot Matayoshi, chair of the House Committee on Consumer Protection & Commerce. “These tactics have addicted another generation to nicotine, with all of the health, economic and educational consequences that come with it.”

Matayoshi said the new law helps close loopholes by requiring manufacturers to verify that their products meet federal requirements before they can be sold in Hawaii.
