While two of you believe that Trident is ok, some others say that they've either had reactions or heard that the conveyer belts MAY be dusted with flour (but I haven't had the time to check up on this yet). I had 6 replies assuring me that Wrigley's gums are gluten free according to the: CSA Cooperative Gluten-Free Commercial Products Listings Celiac Sprue Association/USA PO Box 31700 Omaha, NE 68131-0700 (cost: $8.00) 3 people believe that all altoids are gluten-free, but one person was not sure about the cinnamon.
