I don't know if I could choke down a cigarette. About 3 months after I switched to vaping, I tried a cigarette, just to see if I was done with them. I couldn't finish 2 puffs, it was completely disgusting. Haven't tried one since. I still have an unopened "trophy" pack - it'll be 8 years old in a couple months.
I had to relight that cigarette a bunch of times and it was so long ago I am not sure exactly how much of it I finished. Just remember I could not get the stink off me!
