Definitions

  • the present application relates to the field of smoking sets, and in particular, relates to a smoking set.
  • Smoking articles such as cigarettes and cigars burn tobacco to produce smoke during use. Attempts have been made to provide substitutes for these tobacco-burning articles by producing products that release compounds without burning. Examples of such products are so-called incombustible products which are incombustible when heated and release compounds by heating instead of burning tobacco.
