dr.-pepper-eliquid-flavor Doc Popular e Liquid combines 23 flavors in order to create a soda-flavored eLiquid that is similar to root beer and cola. It has a unique spicy, yet sweet flavor that tastes just like the real thing. It is the perfect vape that provides a great mix of flavor and throat hit. Try adding Vapor4Life’s Cherry eLiquid (Bold) or Vanilla eLiquid (Smooth) for a little more sweetness for your eCig tank or Smileomizer.
