Glantz is among a handful of public health advocates who fear that tobacco companies will end up gaming the regulatory process to enhance the reputation of their products.
Altria - the parent company of industry leader Philip Morris, which might have an easier time maintaining dominance in a more regulated market - endorses the bill.
"Our goal, under the federal regulation, would be to design the best products we can for someone who wants to enjoy tobacco without the health risks," said company spokesman William Phelps. Other manufacturers oppose the legislation.
