Is it normal that smoking makes me more social?

I don't like having to smoke just to get me to open up more and gives me a boost to be more active and have more of a get-up and go fuck it attitude. Why can't I just be that way without smoking cigarettes? My lungs are still considered virgin lungs, I only ever social smoked, which means I can go weeks, months, even years apart from smoking another. Even light cigarettes give me a high. Can an introvert even be able to be more social and active without help from a cigarette?
