Chain smoking
(重定向自Chainsmoke)

Chain smoking is the practice of smoking several cigarettes in succession, sometimes using the ember of a finished cigarette to light the next. Often the term chain smoker refers to a person who smokes relatively constantly, not necessarily chaining each cigarette. The term applies primarily to cigarettes, although it can be used to describe incessant cigar and pipe smoking as well. It is a common form of addiction.
