Thank you so much for everyone who answered!
So, definetely I bought a very weak tobacco.
Today I got a cuban cigar (Petit Quintero, of Cienfuegos, Cuba), and when I was almost finishing it, it got me. I felt everything that you guys said.
A sensation as if the whole weight of my body had gone away. I didn't feel dizzy, or something like that, but all I wanted to do that moment was lie down and stay there.
Was a feeling that I never experienced before, maybe similar to when my blood pressure drop, but without dizziness.
A few minutes later, I started to feel a little nauseated, as if I was going to be sick, but it didn't last long.
I didn't eat anything today, and I smoked the cigar at the end of the day, so I guess that helped...
As for the cigar itself, it was not an interesting experience for me as the pipe. I probably won't buy another one. But I definitely need to buy some better quality tobacco for my pipe.
As some of you have said, smoking a pipe is more for the experience, for the "ritual" of smoking it.
It was interesting to feel what I felt today, but it is not something I would look for. That feeling of "weightless" was very good, but not the feeling of nausea afterwards...
Thanks again to everyone who responded!
