Am I a smoker?

I made stupid in the moment mistakes at a couple parties. I tried a puff of a smoke at a house party. And this wouldn't be horrible but then I tried it a couple months later at school, and then I did that about two or three more times in the next couple months. And after that I used a hookah at another party, and then I tried chew. Now I am seriously trying to never do any of it again because nicotine genuinely scares me. I'm scared next time I'm at a party I'm going to do it and next thing you know I'll be 45 coughing my lungs out like my family members. I have never heard any stories of people trying it a couple times and then never doing it again and being free of it. I don't want to be addicted and have to struggle with quitting for the rest of my life. Will I start craving them now? Has anyone been smoke free and happy without them even after trying it a couple times?
