Why artificial sweeteners and not something else?
We certainly have considered alternate sweeteners, but have found that they are not nearly as effective at masking the bite and harshness of the nicotine.
Fortunately, despite a long history of use in food and pharmaceuticals, neither maltitol, sorbitol, acesulfame potassium, sucralose, or saccharin have been associated with negative health effects at the (small) amounts that any person would realistically consume from our product. In fact, some of the sweeteners you prefer (e.g. xylitol, erythritol) are in the same class of sweeteners as ours: sugar alcohols.
We assure you that we take great care in selecting the ingredients we use and how we formulate the product, and would only include sweeteners that have established evidence and history of safe use in humans at the quantities used in our product.
