Using its patented technology, the Volcano draws in filtered air, heats it to vaporization-ready temperatures, and passes it over your favorite herbal blends, resulting in pure vapor with none of the carcinogens that accompany combustion. In addition to cleaning up your inhalations, the process intensifies the active ingredients of your herbal matter by over 75%, bringing you incredible efficiency. As the vapor forms, it fills up the attached balloon where it can be enjoyed immediately or stored for up to eight hours.
