Both of these links go to self-reported data about how addicted people feel themselves to be, which I don't think is credible at all. It's very common for addicts to falsely believe that they're not addicted and could quit whenever they want.
This is an incredible and outright lie.
Actually try reading the page I linked, there are plenty of links to scientific studies, scientific reviews, and high-quality resources, as well as lots of careful notes about serious confounds in the usual studies. This includes in exactly the sections I linked.
By all means still be cautious and not careless about using the stuff, that is a perfectly sane position. But I think it is very clear that e.g. patches and gum are highly unlikely to have anything even approaching the risk profile of classic tobacco products.
