Other studies have shown vaping to be even worse than smoking.

Do they? I have not come across any that do, including the report you link, which makes it clear that vaping is significantly less damaging.

E-cigs don't burn, so people aren't as exposed to those toxins. A 2015 expert review from Public Health England estimated e-cigs are 95% less harmful than the real thing.

That figure is controversial and might be a little high, says Kenneth Warner, a tobacco policy researcher at the University of Michigan. But, he adds, "The worst critics of e-cigarettes would probably argue they're a half to two-thirds less dangerous. But from a practical view, they're probably on the order of 80% to 85% less dangerous, at least."

Some states and communities that ban smoking in public places also ban vaping. But, Warner says, while the danger from secondhand vapor isn't zero, "it's probably very low."

Vaping is less anti-social than smoking. But wouldn't it be easier for the rest of us if these addicts just injected their nicotine, like all the other druggies?
