I don't know about this one. Cigarettes specifically certainly have enough chronic downsides to outweigh their upsides for me, but nicotine in general serves as a pretty good, light dopamine hit, with relatively few acute downsides. You don't intoxicated, it doesn't take long to ingest, and it's available enough to not become life-consuming. It's not a coincidence that it's a very common habit.

I say this as someone who used to use cigarettes, but took up vaping nicotine instead when I realized it didn't make my clothes reek and scratched the same itch. Everybody has habits around dopamine management. Some people snack, some people spend too much time on social media, some people gamble (in casinos or in brokerages). Personally, I'm prone to snacking, and I eventually realized I could either smoke and be attractive, or snack and get fat. It was an easy enough choice.
