Poland will not adopt it in foreseeable future because it makes no sense: the Polish currency (zloty) acts as a kind of bumper in difficult times. It's very simple: something bad happens like a crisis or a war, investors immediately sell assets deemed as risky (such as zloty), zloty goes down by x%, and automatically Polish products and services become more attractive by x%. This all happens by itself. So for the Polish economy it's a no brainer.
For people themselves, they're not so keen either as they know well adopting euro was abused in other countries to increase prices (and not just round them up a bit). So basically nobody wants it, even if there are a few real benefits of joining, such as potentially lower mortgage rates which are among the highest in the EU).
