“If people have difficulty overcoming both nicotine dependence and long-term habit change, then surely the solution is to help them avoid most of the health risks with only a minimal alteration in their nicotine-seeking habits. This implies a nicotine replacement device which looks like a cigarette and delivers cigarette-like boli of nicotine, but does not deliver the tar and carbon monoxide which cause he vast majority of smoking-related disease … the development and promotion of such a product [and its eventual replacement of tobacco] could have massive beneficial public health implications lasting into the 21st century.”
