Attorneys general from more than two dozen states want federal regulators to impose restrictions on electronic cigarettes, including a ban on the more than 7,000 flavors now available.
In a letter Friday to the Food and Drug Administration, they say limits on advertising and prohibiting flavors besides tobacco and menthol will help protect minors.
New York Attorney General Eric Schneiderman says that while they contain no tobacco, e-cigarettes have all the same addictive qualities as regular cigarettes.
In April, the federal agency proposed treating e-cigarettes as tobacco products, putting them under its regulatory control.
Cigarette maker Altria says the FDA should determine appropriate product standards and marketing restrictions based on science and evidence, respect adult consumer preferences and not automatically apply cigarette restrictions to e-vapor products.
