Theres an awesome thing about being an adult and making independent choices- you can make your own. If you don't want to smoke, that's great, you are not obligated to smoke.
If you do want to? Awesome, your money and your life and as long as you aren't being a butt (smoking around lots of people and in very tight spaces) that's your choice. It is not your place to call other adults stupid for making a choice that you are not. Their bodies, their health, absolutely none of your business
I would say for me its a habit not an addiction (I watch myself pretty carefully to try an avoid it developing into an addiction). I grew up with a smoker so I've always been exposed it and the first time was when i was 19 or 20... I primarily smoke when I'm out with friends and being social, or having a VERY bad anxiety night (which are fortunately very rare) or hookah with my roommates. Idk. I maybe go through a pack every few months so its not a normal thing
