• 燻蒸くんじょうCommon
  noun, suru verb, transitive verbDespite the gloss 'smoking (out)', this is not about tobacco: it means fumigation, or driving out insects or pests with smoke. It is seldom the word you want for the everyday sense of 'smoking'.

Use 喫煙 for the act of smoking tobacco; 燻蒸 means fumigation or smoking pests out with smoke, so it is not the word for a person's smoking habit.
