Sweden is unusual in that it has a culture of using snus, a non-smoking tobacco preparation, and in fact it is unique among the EU member states in having it actually be legal (it's banned EU-wide, but Sweden got an opt-out in the accession negotiations). Neighbouring Norway also has legal snus but Norway isn't a full EU member.

This probably contributes to the low smoking rates, but it also means that Swedish politicians love acting like the tobacco industry is their best friend,[1][2] because it's in the national interest to protect this uniquely Swedish tradition or whatever. And recently, the so-called white snus (Swedicism; English name is nicotine pouches, only Sweden considers this a kind of snus) like ZYN is a way for the Swedish tobacco industry to get a new generation of young people hooked in nicotine, interestingly including ones outside Sweden.
