Just as Gov. William Weld was signing the nation’s first state law requiring cigarette makers to disclose the additives they use in each brand, four tobacco companies sued Friday to block the effort.
The companies say federal law preempts the new state law.
They also argue that the additives are trade secrets that give cigarettes their distinctive flavors and aromas, and disclosing those secrets could hurt their business.
Ilene Hoffer, Gov. Weld’s spokeswoman, said, “This bill merely extends that same kind of information disclosure to tobacco companies without even requiring them to put the information on the package.”
