I don’t have a link for you or anything but just want to point out that it’s not just roads that are covered over time, otherwise archeology would be basically non-existent. For example, if ancient Roman stuff is commonly found in the UK ~5 ft or more under the ground, it makes sense that the roads would also be 5 ft under ground.
A lot of the roads that the Roman’s used are routes that are still in use today. If you’re going to pave a road from point A to point B, and there is already an old road there, might as well just build the new road right on top of the old one. You even out the sides of the road when building it, add some natural/artifical sedimentation over the next hundred years, and boom, the road and the whole area around the road is a few inches higher than it used to be.
This happens a few times over a few centuries and you end up with something that looks like the above. I’m not saying that that is an actual slice of a real road, but I don’t think that it necessarily means that it’s not possible.
Yes, they do offer them in varying levels of nicotine. I decided about a month ago to stop vaping after doing it daily for 10 years. Ordered some patches and some gum, and while I was waiting on those I tried the pouches. They do work and you can get them in lower strengths to wean yourself off.
If your goal is to quit nicotine entirely, be careful that you don’t just fully swap one addiction for another. I’m still working on getting off of the pouches, but it’s getting better, and my lungs feel so much better now.
