The Volcano Medic Complete Kit is a great option for medical cannabis patients due to the way it uses hot air versus conduction or convection heating. Not only does this help to reduce the risk of methanol and acetic acid, the way in which it uses a balloon helps to create a safer inhalation process since the patient does not come into contact with the electricity or heat created from the generator. Plus, the mouthpiece has a check valve which helps to prevent exhalation into the valve balloon, minimizing contamination. The kit comes complete with the Volcano Complete Kit heater, five valve balloons with mouthpieces, three lip pieces, a filling chamber, filling chamber ring, normal screen set, liquid/concentrate pad set, air filter set, herb grinder, cleaning brush, and a user manual.
