Abstract: A wearable system for dispensing a substance is disclosed. The wearable system includes a base element, at least one reservoir surface defining a reservoir disposed in the base element, at least one first opening disposed along on an outward facing portion of the base element and providing fluid communication with the reservoir, and a rolling element disposed in the at least one first opening such that a first portion of the rolling element is outside the base element and a second portion of the rolling element is inside the base element.

Abstract: A fluid-based electronic cigarette system, including a first electronic cigarette that including at least a first housing with a first interfacing surface. In addition, the first electronic cigarette includes a first reservoir and a first mouthpiece. Also, the system includes a second electronic cigarette, which contains at least a second housing. The second housing has a second interfacing surface, a second reservoir, and a second mouthpiece. In addition, an assembled configuration is formed when the first interfacing surface removably connects to the second interfacing surface. In the assembled configuration, a unitary mouthpiece formed by the first mouthpiece and the second mouthpiece.
