Spruce gum is a chewing material made from the resin of spruce trees. In North America spruce resin was chewed by Native Americans and was later introduced to the early American pioneers and was sold commercially by the 19th century by John B. Curtis amongst others. In the 20th century commercial spruce tree processing turned to paper manufacturing to meet demand from the newspaper industry thereby reducing the availability of spruce for other purposes including spruce gum.
