If you try smoking out of PVC pipe, microplastics will be the least of your concerns. PVC is a thermo hardening plastic, which means it doesn’t simply melt but instead starts to decompose when heated. As it decomposes it releases fun stuff like toxins, carcinogenics and chlorine gas.
In the past PVC was everywhere, these days it’s mostly gone. There has been a big push to reduce the use of PVC as much as possible. For sewage it’s still used a lot because the risks are low, but a lot of other places it’s gone.
Um hate to break it to you, but we use PVC conduit a lot in the electrical industry. It’s the only conduit rated for underground use (except galvanized rigid, but that shit’s stupid expensive, and it’ll still rust out eventually).

It’s also the go-to for irrigation piping.
But doesn’t the sewage end up somewhere eventually where we would rather not have it be full of extra toxins
Thankfully sewage is not very hot once it is down in the pipes so they don’t leech out the gross stuff.
Actually, it’s an extremely aerobic environment full of organic compounds and bacteria, that is remarkably active and generates a lot of heat.
So much heat that where I live it is harvested to heat buildings.
