Dr. Pepper Chewing Gum (Amurol, 1980s)
In the 1980s, Amurol (the company behind Big League Chew) produced Dr. Pepper chewing gum. This gum had a liquid center full of Dr. Pepper. (This liquid center gum was made popular by Freshen Up gum.) At the same time, there were a multitude of soda flavored liquid center gums, including A&W and 7Up.
A few years ago, Hubba Bubba, a division of Wrigley’s, redid the gum but without the liquid center. This gum can often be found up for auction on eBay or for sale on Amazon.
