Candy for Ashkenazi

Question

R. Abadi, An Ashkenazi friend would like to use the Sweet-N-Low candies on the list. She has a medical condition allowing her the use of kitniyot. Are there any other Sepharadi-specific inyanim involved, (ie., chozer v'neor) that would be a problem for her, or is it only a kitniyot issue? Same question re: sugar-free Wrigleys Gum. Thanks, and kol hakavod for your hard work.
