"the swollen stem of E. inflatum is due to high concentrations of carbon dioxide in the solid stem and seems to be related to gas regulation. Some insects utilize the swollen stem as a larder, but the inflation is not caused by the larval feeding of gall insects.

It is known that some Native American tribes that once inhabited the surrounding areas of the Las Vegas Valley (most commonly Paiute) would remove the stalk of E. inflatum at the base, and then cut the inflated bulb in half, producing a makeshift pipe. A mixture of Indian Tobacco and Mistletoe would be smoked primarily for leisure purposes. Source Wikipedia
