Beverly Crusher tries her first chewing gum.
Chewing gum was a flavored Earth concoction, which Humans chewed but did not consume.
In 2375, during a game of baseball in the holosuite, Julian Bashir was confused by the notion of a food that one simply chews. Miles O'Brien told Julian that his chewing gum was Scotch flavored. (DS9: "Take Me Out to the Holosuite")
