Barb - I share your feelings. I never smoked but have had loved ones who did and it has been so difficult for me to understand why some people seem to quit so easily and others cannot. My son, for whom I've been a caregiver is a non-smoker. He's the one that got cancer whle my other son (five years older) who has been a long time smoker has never had cancer of any kind! (so far) From what I've learned, nagging the person doesn't help so I'm still learning and when I find the "right moment", I share with my older son what I've learned about cancer and its effects.
