Vaping isn't great, but three things: 1) based on comprehensive, independent reviews of the scientific evidence by both Public Health England (the English Government Public Health agency), the Tobacco Advisory Committee, and other agencies, it's understood to be 95% safer than smoking. 2) second-hand vape is 99% safer than second-hand cigarette smoke, and 3) vaping doesn't stink in the same way and it doesn't linger as long.

That being said, the fastest growing nicotine intake method is nicotine pouches like Zyn, which are even safer than vaping, have no second-hand effects, and don't have any noticeable odor. They also have much less waste and most of it (the fabric pouch and shredded fibers) are biodegradable. Other than nicotine gum and lozenges, I consider that to be the best ideal substitute for smoking by far.

At that point, it's barely much of a concern at all. Nicotine pouches are safer than alcohol, and I don't care if people enjoy nicotine. I just don't like the parts of smoking that affect other people: health burden, second-hand health burden, and smell.
