Chainsmoker

Chain smoking is the practice of smoking several cigarettes in succession, sometimes using the ember of a finishing cigarette to light the next. The term chain smoker often also refers to a person who smokes relatively constantly, though 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 as vaping and the smoking of other substances such as cannabis. It is a common indicator of addiction.
