What cigarettes have no preservatives?

Apparently Winstons have no additives. I am not sure if that is true any more. Dunhill had no additives in Canada but they started putting in Glycol or something like that. I am not sure about the international ones.

Dunhill in the UK advertise no additives. So far as I'm aware these are the only non-additive cigarettes you can buy easily in the UK without going to specialist tobacconists.

Marlobors are fullllllllll of additives. That's why they taste so good (until around 10m after you've finished your cigarette and you get that sulphur-breathe. mmm nice). I would stay away.. The amonia content is very high in that brand. I also find these the hardest to give up - crazy withdrawal symptoms.

Usually the brands like to boast that they are additive free. you will see something on their packs. (Update as at Aug 08) -

American Spirit Nat Sherman Dunhill (red or blue; the usual options at places like supermarkets / newsagents in the UK)
