I e-mail a B.Brown at the RJ Reynolds WWW site.<[log in to unmask]> and was
referred to the Consumer relations department at 1-800-252-3500.

They said  all there cigarettes except Winston have 6% additives..
Winston is 100% tobacco.  She said they would send me information via
mail on Doral's and Winstons but that is all they will say for now.  She
(did not get the name) will talk to others about the filters and
additives..   I will post any  mail I receive from them.
