Are cigarettes really addictive?

I dont understand why people smoke. I tried smoking a few times (because im a dumb and dont ever do it) but i didnt really get those effects on me. My friends say it makes you feel great and kinda high. Yes, but for 10 fvcking seconds. After that all youve left with is that terrible taste in your mouth. People say they feel really bad if they dont smoke for a while. However I never got that feeling. Are people real about cigarettes? Are cigarettes really addictive? Do they really make you feel great?
