Chain smoking is the practice of
smoking several
cigarettes in succession, sometimes using the ember of a finished cigarette to light the next. The term chain smoker often also refers to a person who

Clinical use
Chain smoking is given as an example of excessive
addictive behaviour in the
Diagnostic and Statistical Manual of Mental Disorders. It may be used as a form of
aversion therapy for smokers who are unused to such heavy smoking, inducing them to give up altogether.
