It took a heart attack over 9 years ago to cause me to quit smoking.... part of my heart failure was contributed to smoking tobacco. if that doesn't cause a person to quit smoking nothing short of death will. I tried the vaping I coughed more than when I was a menthol cig nut.... I'll say this I'd probably still be smoking if I didn't have the heart attack...Don't wait to have anything abnormal checked on.... one day could make the difference in treatment and recovery on to remission versus a trip to the Funeral parlor.
