I will add my story. I smoked for over 40 years. It was difficult and emotional. I did taper down to three cigarettes a day. My choice of time. It bothered me that I was weak and could not quit. I kept two in a drawer when was time to quit. It was a great day when I threw them away. For a long time I wanted to go back but didn’t. That’s about 25 years ago. I do have copd but every day my lungs get stronger. I know there is no cure but there’s a healing process. Our bodies were made to heal but due to poor choices mine will never be complete. Today to begin is better than tomorrow. God be with you.
