National Chewing Gum Day is observed worldwide every September 30, celebrating one of the most popular confections. This holiday honors the history of chewing gum, which dates back centuries, with early versions made from natural tree resins. The commercial production of chewing gum began in the mid-19th century, initiated by John B. Curtis, who created "State of Maine Pure Spruce Gum." The modern chewing gum industry was established by Thomas Adams, who developed a product based on chicle in 1870. Celebrations typically involve buying and sharing favorite chewing gum, reminiscing about childhood bubble gum experiences, and participating in bubble-blowing contests. Additionally, people may enjoy bubble gum-flavored treats and share their celebrations on social media using the hashtag #NationalChewingGumDay.
