Hey OP, I'm 27 and started smoking about 2 months ago.
After half a box it had started to feel very relaxing. I was able to observe how the whole body moves slightly due to heart pulse and it seemed like the weight of the world was lifted off my shoulders. It still happens when smoking after abstaining for 12+ hours, after meals or any hard work.
Part of the reason to start was to get accustomed to smoke, after trying weed and not seeing what's the big deal about it. Second and third time it felt much much better.
Today I still smoke mainly due to low self esteem, more heavily when depression hits and it seems right to punish self in some way. Besides, it does feel somewhat nice.
If you're curious, go for it. Part of the reason why we're here is to try out new things.
