Abstract: A dual vaporizer mixing system has a vapor generator with a first chimney and a second chimney. The first chimney generates a first vapor column having a first flavor, and the second chimney generates a second vapor column having a second flavor. A regulator is connected to the vapor generator and receives vapor from the vapor generator. A mouthpiece is connected to the regulator and receives vapor from the regulator. A flavor selector is swivel mounted to a swivel joint. The swivel joint is formed on the regulator. The flavor selector has a first flavor selection that allows passage of the first vapor column through the regulator. The flavor selector has a second flavor selection that allows passage of the second vapor column through the regulator.
