Shiazo steaming is not smoking
Shiazo simulates smoke but does not generate it. The mode of operation of Shiazo is the same as for the so called electronic cigarettes. In both cases an evaporation of fog liquids takes place.
Hereby no solid particles are released, but only fine liquid particles in the form of vapour. Shiazo does not generate smoke, because smoke is defined as a combustion product of organic substances with a mixture of solid particles and air. Shiazo is also free of nicotine. By using Shiazo with an electronic charcoal instead of real charcoal also no PAH, heavy metals or carbon monoxide occurs either.
Therefore Shiazo is comparable to an electronic cigarette and in addition to that it is completely free of nicotine..
