The e-cigarette industry warned Thursday that the FDA’s move to regulate its products will end up shutting down entire businesses and product lines, and said it’s pushing for Congress to avoid that outcome with a legislative tweak to the rule.

The Food and Drug Administration issued a final rule on Thursday outlining how it will regulate e-cigarettes and other products such as cigars and hookahs. The rule has a grandfather date that says any e-cigarette product made after February 2007 must be submitted to the FDA, which will review the ingredients, product design and health risks.
