There are numerous other options for supporting smoking cessation that do not risk lung injury.

Counter-point: For someone who's used to smoking or vaping, the craving to "take a puff" can be a very strong, maybe stronger than the chemical dependence on nicotine itself.

Sure, and removing one appealing option that many people like still means some people will keep smoking who would have quit.
