Man, I went round and round with those cigarettes back in the day. I was up to a couple of packs a day, sometimes more.
What did the trick was when I finally accepted that smoking is sinful behavior and I started asking the Lord to forgive me for sinning each time I smoked. And the Lord gave me revelation that He created my lungs to breathe AIR, not smoke (that's real deep

)
I could not keep sinning and remain in right standing with the Lord so I quit smoking.
Clean living is sooooooo much better than playing with sinful behavior.
