Chewing gum is a soft, cohesive substance designed to be chewed without being swallowed. Humans have used chewing gum in some form for at least 100,000 years. The first flavored chewing gum was created in the 1860 year by John Colgan, a Louisville, Kentucky medical pharmacist. Colgan mixed with powdered sweet sugar the aromatic flavoring tolu and a powder obtained from an extract of the balsam tree (Myroxylon), creating small sticks of flavored chewing gum he named “Taffy Tolu”. Various myths hold that swallowed gum will remain in a human’s stomach for up to 7 years, as it is not digestible.
