No the other way around. Smoking hits you very fast, almost instantly because it’s very fine particles that pass into the bloodstream. Vaping is much slower because it’s vaporized droplets that get absorbed slowly through mucus membrane, and it’s less effective (like 50% effective after 30 min vs. 100% after 5 min). Nicotine salt e-liquid “improves” that a bit to hit faster, to help people stop smoking. You can find articles and papers on this.
You mean we should just cut emissions and not try to remove CO2? Or am I missing something in the article?
I don’t think we can do enough off that list to make enough difference. And we’re already hitting positive feedback cycles so we need some way to remove CO2. I doubt either of those things will happen, but theoretically we need both now.
