Tis true. Since the FDA has taken oversight of tobacco it is requiring manufacturers to disclose all ingredients in their products. Understandably, the Europeans are loathe to disclose proprietary information so they are taking a pass on doing business here.
Its the typical double edged sword. The Feds want to erase tobacco use in the USA under the guise of protecting children from tobacco products that smell good. In this case, mission accomplished. So now the projected tax dollars on said products will be a shortfall. Want to guess how that gap will be filled?
