I had the same experience, I think I even tried a few times over the course of years after I’d forget how bad the previous experience was. Each time it was the same, “Why the fuck do people do this? This fucking sucks.” And I grew up in a household where my Dad smoked constantly throughout his life, I had been around cigarette smoke for awhile.
There’s other addictions I can understand, and even have myself, but smoking is such a harmful, nasty addiction that I can’t get how anybody can willingly do that to themselves repeatedly.
