Barb,
In case you missed this thread I started last week, check out the link in my post. It might help you understand the addictive nature of nicotine and why it is so hard for people to stop.

I discuss smoke cessation almost daily with my patients and I agree with some statistics that I recently read that 80% of the people that smoke, want to stop. I think that the 20% that don't, either think that they won't get cancer or they enjoy smoking so much, they really don't care! Do you know that there have been cases of people smoking through their trach hole after having throat cancer? Hard for us non-smokers to understand.
