On the other, maintained nicotine addiction at a population level may significantly hinder
tobacco endgame efforts," he says.
That all depends on the goal of the endgame, doesn't it?
If the goal is to reduce the toll of disease and death from smoking, then maintained nicotine addiction does not interfere with the goal, as long as the delivery mechanism isn't smoke.
If the goal is to eliminate all use of
tobacco and nicotine world-wide, then yes, the endgame is hindered. But if that's the case, how likely is that particular goal to be successful if e-cigarettes are stamped out? Name one drug whose use has ever been eliminated world-wide.
